Description
Technical Field
The invention relates to a performance equipment control technology, in particular to a multi-professional collaborative editing and control method for films, televisions and stages.
Background
One of the more prominent problems in the programming of shows is the coordination and synchronization control among the various specialties (audio, video, lighting, mechanical, etc.). In a large performance, each specialty is relatively independent, and a relatively large team is needed to ensure smooth arrangement and performance of the performance. In the process of scheduling professional programs, much of the time is spent in coordinating and synchronizing the specialties and much more time is likely to be spent than actually focusing on the programs themselves.
Since each specialty is relatively independent, the control modes are quite different. If the audio and video of a site is to be edited synchronously, the video is controlled by the lamp console, the audio is controlled by multi-track playback editing, the audio is easily positioned to any time to start playback, but the video can only start from the beginning (the frame number can be manually adjusted to the corresponding position by an operator, but the video cannot be started along with the time code), and the control method has insufficient flexibility for site performance control.
In addition, after the positions of the sound boxes of the professional sound box system of the conventional movie and stage are fixed, the sound images are roughly set at the central position of the stage through the left and right channel main loudspeakers or the left, middle and right main loudspeakers on the two sides of the stage.
Therefore, it is a key technical problem to be solved urgently in the technical field to solve the problems of editing and synchronous control of the performance programs and flexible control of the sound image running effect at present.
Disclosure of Invention
the invention aims to provide a multi-professional collaborative editing and control method which can simplify multi-professional control of performances in occasions such as movies and stages and can flexibly and quickly set sound images of a sound amplification system.
in order to solve the technical problems, the invention adopts the technical scheme that: a multi-professional collaborative editing and control method comprises the following steps: displaying a time axis on a display interface of the integrated console; adding and/or deleting tracks for controlling corresponding performance equipment, wherein the tracks comprise one or more of audio tracks, video tracks, light tracks and device tracks; editing track attributes; adding materials; editing material attributes; and the integrated console sends out corresponding control instructions according to the attributes of the tracks and the material attributes of the tracks.
Compared with the prior art, the beneficial effects are as follows: the playback master control embodies the concept of 'performance integrated management'. From a technical point of view, the coupling of the several units is very low, they can work independently without mutual influence, and the only prominent connection is "time", i.e. when and what is played out. From the user's perspective, the relationship of "time" is what they are most interested in. If the states of the several units can be collectively viewed and managed, the user will be relieved of many unnecessary troubles. Such as coordinating synchronization issues among the various units, professional cross-referencing and contrast correction during program editing, etc.

Detailed Description
The following describes the sound image trajectory control according to various embodiments of the present invention with reference to the drawings.
the embodiment provides a multi-professional collaborative editing and control method for movies and stages, which can simplify multi-professional control of performances in occasions such as movies and stages and can flexibly and quickly set sound images of a sound amplification system. The method realizes centralized arrangement and control of a plurality of professional materials through a multi-track playback editing module of an integrated console.
As shown in fig. 1, the film, television and stage oriented multi-professional collaborative editing and control method includes the following steps:
s101: displaying a time axis on a display interface of the integrated console;
S102: adding and/or deleting tracks for controlling corresponding performance equipment, wherein the tracks comprise one or more of audio tracks, video tracks, light tracks and device tracks;
S103: editing track attributes;
S104: adding materials;
S105: editing material attributes;
S106: and the integrated console sends out corresponding control instructions according to the attributes of the tracks and the material attributes of the tracks.
As shown in fig. 2 and fig. 12, the multi-professional collaborative editing and controlling method optionally includes multi-track audio playback control (corresponding to the following audio control modules), and at this time, the method includes the following steps:
S201: adding an audio track, and adding one or more audio tracks (areas) 1 and 2 which are parallel and aligned to the time axis on a display interface, wherein each audio track corresponds to an output channel.
S202: editing audio track attributes, wherein the audio track attributes comprise track locking and track muting. The track mute property can control whether audio materials and all sub-tracks on the track are muted or not, and the track mute property is the master control of the audio tracks. The track locking attribute can control individual attributes of the track except for muting and adding hidden sub-tracks, and other attributes and material positions and material attributes in the audio track cannot be modified.
s203: adding audio material, adding one or more audio materials 111, 112, 113, 211, 212, 213, 214 in the audio tracks 1, 2, and generating audio material corresponding to the audio material in the audio tracks, wherein the length of the audio tracks occupied by the audio material is matched with the total duration of the audio material. Before adding the audio materials, an audio material list is obtained from an audio server, and then the audio materials are selected from the audio material list to be added into an audio track. After the audio materials are added into the audio track, the audio attribute files corresponding to the audio materials are generated, the integrated console controls the instruction sent to the audio server by editing the audio attribute files instead of directly calling or editing the source files corresponding to the audio materials, and therefore the safety of the source files and the stability of the integrated console are guaranteed.
S204: and editing the audio material attributes, wherein the audio material attributes comprise a starting point position, an end point position, a starting time, an ending time, a total duration and a playing time length. The starting point is a time axis time corresponding to the starting point (in the vertical direction) of the audio material, the ending point is a time axis time corresponding to the ending point (in the vertical direction) of the audio material, the starting time is an actual playing starting time of the audio material on a time axis, and the ending time is an actual playing ending position of the audio material on the time axis. Generally, the start time may be delayed from the start position and the end time may be advanced from the end position. The total duration refers to the original time length of the audio material, the time difference from the starting position to the end position is the total duration of the audio material, the playing time length refers to the playing time length of the audio material on a time axis, and the time difference between the starting time and the ending time is the playing time length of the audio material. The cutting operation of the sound image material can be realized by adjusting the starting time and the ending time, namely, only the part which is expected to be played by the user is played.
The start position and the end position can be changed by adjusting (laterally moving) the position of the audio material in the audio track, but the relative positions of the start position and the end position on the time axis do not change, that is, the length of the audio material does not change. The actual playing time of the audio material and the length thereof on the time axis can be changed by adjusting the start time and the end time of the audio material. A plurality of audio materials may be placed in an audio track, indicating that the plurality of audio materials may be played sequentially (via the corresponding output channels) during the time period indicated by the time axis. It should be noted that the audio material positions (temporal positions) within any audio track can be freely adjusted, but there should be no overlap between the audio materials.
Furthermore, the integrated console only controls the attribute files corresponding to the audio materials, so that the integrated console can also perform cutting operation and splicing operation on the audio materials. The cutting operation means that one audio material on the audio track is divided into a plurality of audio materials, each divided audio material has a corresponding attribute file, the source file is still intact, and the integrated console sends out control commands according to the new attribute files to sequentially call the source file to perform corresponding playing and sound effect operation. Similarly, the splicing operation refers to combining two audio materials into one audio material, combining their respective attribute files into one attribute file, and sending out a control audio server to call the two audio source files through one attribute file.
Furthermore, a plurality of groups of operation entity operation keys respectively corresponding to the audio tracks can be arranged on the integrated console, so that the attributes of the audio materials can be manually adjusted through the entity operation keys. For example, a material playback time adjustment knob that adjusts the position (time axis position) of the audio material in the audio track back and forth is added.
S205: adding audio sub-tracks 12, 13, 14, 15, 21, 22, adding one or more audio sub-tracks corresponding to one of said audio tracks, each of said audio sub-tracks being parallel to said time axis, said audio sub-tracks corresponding to the output channels of its corresponding said audio track.
each audio track may have an attached audio sub-track, the types of audio sub-tracks including a sound image sub-track and a sound effect sub-track. The sound image sub-track is used for carrying out sound image track processing on part or all of audio materials of the audio track, and the sound effect sub-track is used for carrying out sound effect processing on part or all of audio materials of the audio track. In this step, the following steps may be further performed:
S301: adding a sound image sub-track and sound image materials, adding one or more sound image materials 121, 122 in the sound image sub-track, and generating the sound image materials corresponding to the sound image materials in the sound image sub-track, wherein the length of the sound image sub-track occupied by the sound image materials is matched with the total time length corresponding to the sound image materials.
s302: editing the audio image sub-track attributes, wherein the editable audio image sub-track attributes comprise track locking and track muting.
S303: editing the audio and video material attributes, wherein the audio and video material attributes also comprise a starting point position, an end point position, a starting time, an ending time, a total duration and a playing time length, which are similar to the audio material.
Through the sound image material on the sound image sub-track, the sound image track processing can be carried out on the signal output by the output channel corresponding to the audio track to which the sound image sub-track belongs in the time period between the starting time and the ending time of the sound image material. Therefore, different types of sound image materials are added on the sound image sub-track, and different types of sound image track processing can be carried out on the signals output by the corresponding output channels; and by adjusting the starting position, the ending time, the starting time, and the ending time of each sound image material, the time at which the sound image trajectory processing starts and the time during which the sound image trajectory effect lasts can be adjusted.
Sound image material is distinguished from audio material in that audio material represents audio data. The sound image trajectory data is output level data of each speaker node changing with time in order to make a sound image formed by the output levels of each virtual speaker node in the speaker distribution map run or remain unchanged along a preset path in a time period with a set length. That is, the sound image trajectory data includes output level change data of all the speaker nodes in the speaker distribution map within the set length time period. The type of the sound image track data comprises fixed-point sound image track data, variable-track sound image track data and variable-domain sound image track data, the type of the sound image track data determines the type of a sound image material, and the total time length of sound image motion corresponding to the sound image track data determines the time difference between the starting position and the ending position of the sound image material, namely the total time length of the sound image material. The sound image track processing means that the size of the actual output level of each sound box entity corresponding to each sound box node is adjusted according to the sound image track data, so that the sound image of the sound box entity system runs or keeps still along a set path within a time period of a set length.
S304: sound effect sub-tracks are added, the types of sound effect sub-tracks including volume and gain sub-tracks 13, 22, EQ sub-tracks 14, 15, 21, one volume and gain sub-track for each audio track, and one or more EQ sub-tracks. The volume and gain sub-tracks are used for adjusting the signal level of the output channel corresponding to the audio track, and the EQ sub-tracks are used for carrying out EQ sound effect processing on the output signals of the output channel corresponding to the audio track.
S305: editing the attribute of the sound effect sub-track, wherein the attribute of the sound effect sub-track comprises a track locking, a track muting and a track identification, and sound effect processing parameters corresponding to the type of the sound effect sub-track. For example, the sound effect processing parameter included in the volume and gain sub-track is an output level adjustment parameter, and the sound effect processing parameter included in the EQ sub-track is an EQ processing parameter. The sound effect of the corresponding output channel of the audio track to which the sound effect sub-track belongs can be adjusted by modifying the sound effect parameters of the sound effect sub-track.
S206: and storing data, or generating a control instruction for a source file corresponding to the audio material according to the attributes of the audio track and the sub-tracks thereof, the audio material and the attributes of the acoustic pixel material, and performing play control and acoustic image and sound effect processing control on the source file of the audio material according to the control instruction.
The control instruction comprises an audio source file for determining whether to call (play) the audio material, the starting time and the ending time (based on the time of a time axis) of the playing of the source file, and the audio and sound effect processing of the source file, and the specific control instruction corresponds to the attributes of each audio track and the auxiliary sub-tracks thereof, and the attributes of the audio material and the audio and video material. That is to say, the audio track does not directly call and process the source file of the audio material, but only processes the attribute file corresponding to the audio source file, and realizes indirect control of the audio source file by editing and adjusting the attribute file of the source file, adding/editing the audio image material, and the attributes of the audio track and the sub-tracks thereof.
For example, audio material added to an audio track will enter a playlist, and when the audio track starts playing, the audio material will be played; by editing the audio track attributes, the mute attributes of the audio track can be controlled, whether the audio track and the subsidiary sub-tracks thereof are muted (effective) or not can be controlled, and by editing the audio lock attributes, the audio lock attributes can be controlled, and besides individual attributes such as muting and adding hidden sub-tracks, other attributes, material positions and material attributes in the audio track can not be modified (locked state). Reference is made to the preceding description for more details.
As shown in fig. 4 and fig. 12, the multi-specialty collaborative editing and control method of the present embodiment may further select to add video playback control (corresponding to the following video control modules), and specifically includes the following steps:
s401: and adding a video track (4) (area) which is parallel and aligned to the time axis and corresponds to a controlled device (on a display interface), wherein a video server is adopted in the invention.

Before adding the video material, a video material list is obtained from a video server, and then the video material is selected from the video material list to be added into a video track. After the video material is added into the video track, the video attribute file corresponding to the video material is generated, the integrated console controls the instruction sent to the video server by editing the video attribute file instead of directly calling or editing the source file corresponding to the video material, and the safety of the source file and the stability of the integrated console are ensured.
S404: and editing the video material attributes, wherein the video material attributes comprise a starting point position, an end point position, a starting time, an ending time, a total duration and a playing time length.

The light material is light network control data with a certain time length, such as Artnet data, and the Artnet data is packaged with DMX data. The light materials can be generated in the following way: after the traditional lamp console has arranged the light program, the integrated console is connected to the light network interface on the traditional lamp console through the light network interface, records the light control signal output by the lamp console, and meanwhile, the integrated console needs to print a time code on the recorded light control signal in the recording process so as to carry out editing control on the light track.

further, a device control principle of the multi-professional system editing and control system is shown in fig. 17, and various device control signals output by the integrated console are output to corresponding controlled equipment through various protocol interfaces on the device adapter.
In addition, the integrated console may further include an acoustic image track data generation module for creating (generating) acoustic image track data (i.e., acoustic image material), and the acoustic image track data obtained by the module may be called by the multi-track playback editing execution module, so as to control the audio server track matrix module to control the acoustic image track. Further, the present embodiment provides a sound image trajectory control method, where the control host (e.g., an integrated console, an audio server) sets output level values of each speaker node of an entity speaker system, so that a sound image moves or is stationary in a set manner within a set total duration. As shown in fig. 18, the control method includes:
S181, generating acoustic image trajectory data;
S182, adjusting the output level of each sound box entity according to the sound image track data in the total time length corresponding to the sound image track data;
And S183, overlapping the input level of the signal input to each sound box entity and the output level of the corresponding sound box entity in the total time length to obtain the actual output level of each sound box entity.
the sound image trajectory data is output level data of sound box nodes changing with time in order to make sound images formed by output levels of the virtual sound box nodes in a virtual sound box distribution map on the integrated console run or keep still along a preset path in a time period with a set length (namely, the total duration of sound images). That is, the sound image trajectory data includes output level change data of all the speaker nodes in the speaker distribution map within the set length time period. For each sound box node, the output level of the sound box node changes along with the change of time in the set time period, and the output level may also be zero, a negative number or even negative infinity, and the negative infinity is preferably adopted.
Each loudspeaker node corresponds to a loudspeaker entity in the physical loudspeaker system, and each loudspeaker entity comprises one or more loudspeakers at the same position. That is, each speaker node may correspond to one or more speakers located at the same location. In order to make the physical sound box system reproduce the sound image track route more accurately, the position distribution of each sound virtual sound box node in the sound box distribution map corresponds to the position distribution of each sound box entity of the physical sound box system, especially the relative position relationship between each sound box node corresponds to the relative position relationship between each sound box entity.
The level actually output by the sound box entity is obtained by superposing the level of the input signal and the output level of the sound box node corresponding to the sound box entity in the sound image track data. The former is the characteristics of the input signal, and the latter can be regarded as the characteristics of the sound box entity. At any one time, different input signals have different input levels, and for the same loudspeaker entity, there is only one output level. It can be understood that the sound image trajectory processing is an output level processing for each sound box entity to form a preset sound image trajectory effect (including sound image standstill).
The superposition of the input level and the output level of the sound box entity can be processed before the audio signal is actually input into the sound box entity, or can be processed after the audio signal enters the sound box entity, which depends on the link structure of the whole sound amplifying system, and whether an audio signal processing module, such as a DSP unit, is arranged in the sound box entity.
Types of sound image trajectory data include: fixed point sound image data, variable orbit sound image trajectory data, and variable domain sound image trajectory. In order to facilitate the control of the speed and the process of sound images when the sound image track data are generated on the integrated console in an analog mode, the running path of the sound images is represented by the line segments sequentially connected among the plurality of sound image track control points which are distributed on the sound box distribution map, namely the running path of the sound images and the total running time of the sound images are determined by the plurality of sound image track control points which are distributed in a discrete mode.
The fixed point sound image refers to the situation that one or more selected sound box nodes in a sound box distribution map continuously output the level within a set length of time period, and the output level values of unselected sound box nodes are zero or negative infinity. Accordingly, the fixed point sound image data is output level data in which, during a time period of a set length, one or more selected speaker nodes in the speaker distribution map continuously output levels, and unselected speaker nodes do not output levels, or when the output level value is zero or minus infinity, each speaker node changes with time. For a selected speaker node, its output level is continuous (and may fluctuate up and down) during the set time; and for unselected enclosure nodes, its output level remains negative infinity for the set time.
The variable rail sound image is a situation that in a time period with a set length, in order to enable the sound image to run along a preset path, each sound box node outputs a level according to a certain rule. Accordingly, the variable rail sound image trajectory data is output level data of each sound box node changing with time in order to make the sound image run along a preset path in a time period with a set length. The running path of the sound image is not required to be very precise, and the duration of the sound image movement (running) is not very long, only the sound image running effect recognizable by the listener needs to be approximately created.
The variable domain sound image is a situation that in a time period with a set length, in order to make the sound image run along a preset region, the output level of each sound box node is changed according to a certain rule. Accordingly, the variable-range sound image trajectory data is output level data of each sound box node changing with time in order to make the sound image run along the preset range for a set length of time.
As shown in fig. 19, the variable domain sound image trajectory data of the present embodiment can be obtained by:
s1901: setting a sound box node: and adding or deleting sound box nodes on the sound box distribution map 10.
S1902: and modifying the node attribute of the sound box: the attributes of the speaker nodes include speaker coordinates, speaker type, corresponding output channel, initialization level, speaker name, etc. The sound box nodes are represented by sound box icons on the sound box distribution map, and the coordinate positions of the sound box nodes can be changed by moving the sound box icons. The sound box type refers to a full-frequency sound box or an ultra-low frequency sound box, and the specific type can be divided according to actual needs. Each sound box node in the sound box distribution map is distributed with an output channel, each output channel corresponds to one sound box entity in the entity sound box system, and each sound box entity comprises one or more sound boxes located at the same position. That is, each speaker node may correspond to one or more speakers located at the same location. In order to reproduce the designed sound image running path in the sound box distribution map, the position distribution of the sound box entity should correspond to the position distribution of the sound box nodes in the sound box distribution map.
S1903: dividing the acoustic image area and setting an acoustic image running path:
a certain point is selected on the sound box distribution map as a center S0, sound box nodes are added at the center S0, then a plurality of concentric circle regions are divided by taking the center S0 as a circle center, and the concentric circle with the largest diameter can completely or partially cover the sound box nodes on the sound box distribution map. The region surrounded by the concentric circle with the smallest diameter is set as the acoustic image region Z1, the regions between adjacent concentric circles are set as the acoustic image regions Z2, Z3, Z4 … ZN (N is a natural number equal to or greater than 2), respectively, from the inside to the outside, that is, the region between the concentric circle with the smallest diameter and the concentric circle with the second to last smaller diameter is set as the acoustic image region Z2, the region between the concentric circle with the second to last smaller diameter and the concentric circle with the third to last smaller diameter is set as the acoustic image region Z3, and so on (see fig. 20).
A plurality of running paths radially spreading outward with the center S0 as a starting point are set, each running path being set as a straight line segment traversing each sound image region. These running paths may cover all or part of the nodes of the enclosures in the concentric circular region, preferably all of the nodes of the enclosures in the concentric circular region.
the end points of these running paths are the nodes of the sound boxes within or outside the concentric circle region, the start point of the running path is the center S0, and the end points are different according to the distribution of the nodes of the sound boxes in the running path direction: (1) if there is a sound box node located outside the concentric circle with the largest diameter in the running path direction, the end point of the running path is the sound box node located outside the concentric circle with the largest diameter and having the smallest distance from the concentric circle with the largest diameter in the running path direction. (2) If there is no speaker node outside the largest diameter concentric circle in the running path direction, the end point of the running path is the speaker node farthest from the center S0 in the running path direction.
These running paths have at least one speaker node, and may have two or more speaker nodes.
Referring to fig. 20, the sound box distribution map is provided with four concentric circles centering on S0, the four concentric circles are divided into 4 sound image regions Z1, Z2, Z3, and Z4, 13 sound image running paths are set, which are S1, S2, S3, S4, S5, S6, S7, S8, S9, S10, S11, S12, and S13, and all sound box nodes in the concentric circle region (the region included by the concentric circle with the largest diameter) have corresponding running paths. The running paths S2, S3, S5, S8, S9, S10, S11, S12, and S13 pass through only one speaker node, and the running paths S1, S4, and S7 pass through two speaker nodes.
Referring to fig. 21, further, when a certain point is selected as the center, a certain speaker node may be directly selected as the center. The sound box distribution map of fig. 21 is provided with 5 concentric circles centered on the sound box node S0 ', and divided into 5 sound image regions Z1', Z2 ', Z3', Z4 ', Z5', and a plurality of sound image running paths. The sound image running paths S1 ', S2 ' and S3 ' have 3 sound box nodes, respectively, and at the current time, the sound image track points P41, P42 and P43 on the sound image running paths S1 ', S2 ' and S3 ' are all located in the sound image area Z4 '.
S1904: editing the time attribute of the sound image area, including the time corresponding to the sound image area, the time from the current sound image area to the next sound image area, and the total running time of the sound image. Editing of the acoustic image region attribute is similar to editing of the variable rail acoustic image track point attribute. If the time corresponding to a sound image region is modified, the time corresponding to all the sound image regions before the sound region and the total time length of the sound image running need to be adjusted. If the time required from one sound image area to the next sound image area is adjusted, the time corresponding to the next sound image area and the total running time of the sound images need to be adjusted. If the total time length of the sound image running is modified, the corresponding time of each sound image area on the sound image running path and the time required by the sound image area to the next sound image area are adjusted.
S1905: recording variable domain sound image track data, and recording output level values of all the time points of all the sound box nodes in the process that sound images sequentially run through all the sound image regions along a set running path.
The output level value of the relevant sound box node at a certain moment can be calculated by the following method.
Suppose that: the total time length of the sound image running is set as T, the sound image track point on each running path moves from the starting point to the end point or from the end point to the starting point in the total time length T, and the sound image moving speeds of the running paths can be the same or different.
At a certain time t, the current sound image trajectory point Pj on a certain sound image running path P moves to the next sound image zone Zi +1 along a certain sound image zone Zi. On the route of the sound image running path P, the output levels of the adjacent speaker nodes k and the speaker nodes k +1 on the inner and outer sides of the sound image track point Pj are dBm and dBm +1, respectively, and the output levels of the speaker nodes other than the two speaker nodes on the sound image running path P are zero or negative infinity. The speaker node K and the speaker node K +1 are both speaker nodes located on the sound image running path, where the speaker node K is a speaker node located inside the sound image track point Pj (a side close to the center S0), and the speaker node K +1 is a speaker node located outside the sound image track (a side away from the center S0).
Then, at the present time t, in the course of the sound image trajectory point Pj on the sound image running path P running from the present sound image region Zi to the next sound image region Zi +1,
Output level dBm of sound box node k is 10 · loge η ÷ 2.3025851
Output level dBm +1 of the sound box node k +1 ═ 10 · loge β ÷ 2.3025851
L12 is the distance from the sound box node k to the sound box node k +1, l1P is the distance from the sound box node k to the current sound image track point Pj, and lp2 is the distance from the current sound image track point Pj to the sound box node k + 1. It can be seen from the above formula that each sound image track point on each running path has two speaker node output levels, but when the sound image track point is just located at a speaker node, only one of the speaker nodes outputs a level.
referring to fig. 20, the sound box distribution map is provided with 4 concentric circles with the center S0 as the center, and the center S0 is provided with sound box nodes. The concentric circles are divided into 4 sound image areas Z1, Z2, Z3 and Z4, and 13 sound image running tracks S1, S2, S3, S4, S5, S6, S7, S8, S9, S10, S11, S12 and S13 are provided, wherein the sound image running paths S1, S4, S7 and S10 respectively have 3 sound box nodes, and the rest sound image running paths respectively have only 2 sound box nodes.
At the current time, the current sound image trajectory points P31, P32, P33, P34 of the sound image running paths S1, S2, S3, S4 run into the sound image region Z4. If the sound image moving speed on each sound image running path is the same, these current sound image track points are located on a circle with S0 as the center. At this time, on each audio-video running path, only the audio amplifier nodes on the inner side and the outer side of the current audio-video track point have output levels, and the output levels of the other audio amplifier nodes are zero or negative infinity. Taking the current sound image trajectory P31 as an example, the inside adjacent speaker node is the speaker node located at the upper right in the sound image region Z2 in fig. 20 (the speaker node in fig. 20 is indicated by a small circle), the outside ringing speaker node is the speaker node located at the upper right outside the sound image region Z4, and this speaker node is also the end point of the sound image running path S1. At this time, only the aforementioned two cabinet nodes on the sound image running path S1 have level outputs, and the output level of the cabinet node located at the center S0 is zero or negative infinity.
When the output level values of the sound box nodes at each moment of the variable domain sound image track in the total time length T are recorded, the output level values can be continuously recorded or can be recorded according to a certain frequency. The latter means that the output level value of each sound box node is recorded once every certain time. In the present embodiment, the output level values of the respective speaker nodes when the sound image runs along the set path are recorded with a frequency of 25 frames/second or 30 frames/second. The output level data of each sound box node is recorded according to a certain frequency, so that the data volume can be reduced, the processing speed of the input audio signal during audio-video track processing is increased, and the real-time performance of the audio-video running effect is ensured.
