Description

  The present invention relates to a sound setting support device that supports setting work related to a sound adjustment device when an event such as a concert is held.

For performances such as concerts, an acoustic system including a microphone, an acoustic adjustment device, an amplifier, a speaker, and the like is used. For such a performance, an acoustic plan such as assignment of microphones and speakers is created in advance, and input / output channels and devices are set according to an acoustic plan diagram (pre-setting diagram) based on the acoustic plan.
The acoustic plan diagram shows each instrument's input and output channels, such as which instrument is assigned to the input channel and which microphone is used, which signal is assigned to the output channel, which speaker is used, and which amplifier is used. And the input / output devices assigned to it, and most important attributes are described therein. By using this acoustic plan diagram, it is possible to make a plan that does not fail beforehand and share information with other staff.

In order to mix and process the sound input from one or more input systems and output it to one or more output systems, the acoustic system has an acoustic adjustment console (mixing console, analog mixer or digital). A sound adjusting device such as a mixer is provided.
The sound adjustment console is provided with controls such as multiple faders, and various parameters related to signal processing (for example, parameters such as head amplifiers, equalizers, compressors, etc.) are set for each channel. It was normal for the user to set from scratch on site.
For example, in the case of an analog mixer, the operator manually sets the head amplifier level, PEQ (parametric equalizer) frequency and level, sending to the MIX bus, fader level, pan, etc. for each channel.
Therefore, when there is a change of artist, it is very cumbersome because the settings are recorded by taking notes of the setting values one by one or shooting with the camera, and re-setting while looking at them again. Met.

Further, in the digital mixer, an encoder and an actuator are attached to an operation element such as a fader, and the operation state of the operation element can be automatically detected and set. According to such an apparatus, it is possible to create a certain setting, save it in the scene memory as it is, and call (recall) the saved data for setting (Patent Document 1, Non-Patent Document 1). . For example, during a concert rehearsal, the mixing state set by the operator for each stage condition can be stored in advance in a memory, and the state can be reproduced by recalling it.
Also, the settings of the digital mixer main body can be controlled from the personal computer connected to the digital mixer main body, the setting data in the digital mixer main body can be stored in the personal computer, and the saved data can be set (recalled) in the digital mixer main body. Is also known (Non-Patent Document 2).
JP 2005-217458 A DM2000 instruction manual, P.D. 157, [on line], Yamaha Corporation, [Search May 8, 2007], Internet, (URL: http://www2.yamaha.co.jp/manual/pdf/pa/japan/mixers/DM2000J .pdf) M7CL Editor Instruction Manual, [on line], Yamaha Corporation, [Search May 8, 2007], Internet (URL: http://www2.yamaha.co.jp/manual/pdf/pa/japan) /mixers/m7cleditor_ja_om.pdf)

As described above, when an analog mixer is used as the acoustic adjustment device, initial setting of each operation element must be performed manually by an operator, and complicated operations are required.
In addition, the scene memory function of the digital mixer can save and reproduce the settings at a certain moment on the mixer. However, what event, what instrument is input to which channel, which Attribute (usage status) information such as what speaker was assigned to the output channel was not saved.
In addition, some library functions of digital mixers include recommended presets for equalizers and compressors for each instrument, but this is only a rough estimate, and the characteristics of individual instruments, the preferences of each operator, and the event It did not reflect the optimal value of the site or the know-how of the site.
Furthermore, when an event such as a concert is held, an acoustic plan was created, but this acoustic plan and the setting value of the acoustic adjustment device were not linked.
However, for example, for a certain instrument and microphone, the same setting value is always entered as the initial value. Therefore, if the setting value used in the past can be easily called by specifying the instrument and microphone, It is possible to greatly reduce the labor for initial setting and the like.

  Accordingly, an object of the present invention is to provide an acoustic setting support device that can greatly improve the efficiency of setting work related to an acoustic adjustment device.

In order to achieve the above object, an acoustic setting support device according to the present invention is configured to support a setting operation related to an acoustic adjustment device that performs predetermined signal processing on an input signal from a microphone and supplies an output signal to a speaker. The support device, wherein at least one of the microphone and the speaker in the event of using the sound adjustment device is assigned acoustic plan data and the signal processing data indicating the signal processing content in the sound adjustment device, Storage means for storing together with attribute information of the event related to the setting work; means for acquiring the acoustic plan data and the signal processing data corresponding to the selected attribute information from the storage means; and the storage means The sound plan data acquired from the sound or sound modified from the sound plan data Means for outputting an acoustic plan based on the plan data, and means for creating setting data to be set in the acoustic adjustment device based on the signal processing data acquired from the storage means or signal processing data obtained by modifying the signal processing data And means for setting the acoustic adjustment device based on the setting data.
The attribute information includes at least information on the name of the facility where the event was held, the name or type of the event, the date and time of the event, the name of the performer of the event, or the operator name.
Further, the acquisition means can acquire signal processing data corresponding to attribute information approximate to the selected attribute information.
Furthermore, the means for creating the setting data may be configured by averaging the plurality of signal processing data when a plurality of signal processing data corresponding to the selected attribute information is obtained, or The setting data is created by averaging the most recent signal processing data of the signal processing data with a greater weight.
Furthermore, the database can be accessed from a plurality of the sound setting support devices.

According to the acoustic setting support device of the present invention, the name and type of the event actually used, the name of the facility, the date of the event, the appearance, and the various setting values (signal processing data) in the acoustic plan data and the acoustic adjustment device. Creation of an acoustic plan by linking to event attribute information such as a person name or operator name and storing it in the storage means, and the user acquiring and using an acoustic plan and signal processing data according to the application from the storage means And the initial setting of the sound adjustment device can be greatly reduced.
Since the event attribute information (event date, name, facility name, etc.) is a keyword that is easy for a user to search, an acoustic plan and signal processing data can be easily acquired by searching using the event attribute information. For example, at the event held every year, the setting values used last year can be called for reference, or the contents set by other users in the past at the event at the first venue can be called for reference.
Furthermore, the optimum data can be arbitrarily narrowed down from a plurality of corresponding data by keyword search. For example, even with the same event name, data can be acquired by adding the latest data or specific conditions (further restricting operators, etc.). On the other hand, the conventional technology only acquires one setting data directly by recalling the scene memory, so that it can be used to narrow down the intuitive, functional, or ambiguous search as in the present invention. There wasn't.
Furthermore, when the storage means is a database that can be accessed from a plurality of sound setting support devices, various people can access the database and accumulate data to set various people's know-how. It can be reflected in the network, and can be used from a remote location.

In addition, although not shown in this figure, attribute information of events related to the setting work of other sound systems and sound adjustment consoles such as names of performers or artists, appearance times of each performer or artist are described. .

Next, setting value data (signal processing data) indicating the operation state of the operator in the acoustic adjustment console 5 will be described.
The setting of the acoustic adjustment console 5 can be performed by operating the acoustic adjustment console 5 itself, or can be set using a control program of the acoustic adjustment console mounted on the computer 11. At the time of event rehearsal and actual performance, as described above, various signal processing parameters in each channel (input channel and output channel) are set by operating each operation element of the acoustic adjustment console 5.
FIG. 4 is a diagram illustrating an example of a display screen of the computer 11 when setting is performed from the computer 11 using the control program of the acoustic adjustment console, and setting of signal processing parameters in one selected input channel The screen when performing is shown.
In the figure, reference numeral 41 denotes an area for displaying the number and name of the input channel selected as an operation target. Here, a state in which channel 1 is selected is shown. The operator can switch channels using the SELECT button or the left and right triangle buttons. PATCH is used to select an input source to be assigned to this channel. In this example, input terminal # 1 (IN 1) is selected.

Reference numeral 42 denotes an area for adjusting a send level of signals sent from the input channel to the MIX buses (1 to 16) and the MATRIX buses (1 to 8).
Reference numeral 43 denotes an area for setting the gain of the head amplifier (HA), the presence or absence of inversion of the signal phase (φ), the on / off of the high-pass filter (HPF), and the cutoff frequency.
Reference numeral 44 denotes an area for performing send setting and pan (PAN) setting from the currently selected input channel to the stereo bus / mono bus.

The various signal processing parameters can be similarly set using the parameter setting screen corresponding to each channel in (8, STREO / MONO channel).
As described above, the setting value data (signal processing data) for the input system channels includes, for each channel, the channel name, fader level, send level to MIX, send level to MATRIX, and head amplifier (HA). Parameters such as gain, HPF on / off and cut-off frequency), PAN, gate set value, compressor set value, EQ (equalizer) frequency and level are included.
The signal processing data for the output channel includes parameters such as PEQ (Lo, Mid, Hi, LPF, HPF), GEQ, compressor / limiter, fader position, delay, and speaker processing for each channel. ing.
Such signal processing data for each channel of the input system and the output system is registered in the database 14 as a parameter set. Each record is stored with the name “channel name”. When using the mixer, the “channel name” is always used for the channel to be used (for example, piano Hi / Lo, vocals, announcements, etc.). Records can be registered.

  As described above, when an event is held, the data of the acoustic plan diagram (FIG. 3) used in the event and the set value indicating the operation state (FIG. 4) of the operator of the acoustic adjustment console at that time Data (signal processing data) is stored in the database 14 from the computer 11. At this time, as described above, the acoustic plan data includes the event attribute information (event type, date, facility name, etc.), instrument name, microphone model name, amplifier model name, speaker, etc. In addition, other attribute information (performer or artist name, appearance time of performer or artist, acoustic operator name, etc.) is also stored in the database 14 with the acoustic plan data and signal processing data. Accumulated at the same time as accumulating.

In general, if the attribute is determined, the setting value (signal processing parameter) of the acoustic adjustment console is almost the same. For example, if the instrument and microphone of a certain channel are determined (for example, if the type of microphone that picks up the piano sound is determined), the settings for that channel will be almost the same, and the position of the knob on the operator will vary greatly. There is no.
Therefore, in the present invention, every time an event is held, acoustic plan data and signal processing data related to the event are linked to attributes and stored in the database 14, and new production time (including rehearsal) is also included. ), The database 14 is searched for the attribute, the corresponding acoustic plan data and signal processing data are called up, and the use of this data greatly increases the work of creating the acoustic plan and initial setting of the acoustic adjustment console. Try to reduce. In addition, the operator name and the sound planner name can also be searched, and the production intention and habit of these operators and creators can be used for setting work related to the sound adjustment device.

With reference to FIG. 5, attributes and parameters such as setting values determined according to the attributes will be described.
As shown in the figure, with regard to the attribute of facility, parameters such as system scale, number of speakers, arrangement, and amplifier level are determined for each facility (A hall, XX hall, XX arena, etc.).
For the attribute of event type, parameters such as the type of microphone to be used, the number of input channels, and the amplifier level are determined for each event type (category where the sound system is different, such as rock concerts, musicals, and lectures). come.
As for the attributes of performers and musicians, parameters such as input channel gain, PEQ, and monitor send level are determined for each performer (announcer A, musician B, etc.).

There may be a tendency that the low frequency has been enhanced in the past year as compared to the previous year in accordance with the passage of time such as the past year or the past five years. This attribute uses the date information included in the sound plan data.
For each instrument such as piano, guitar, bass drum, etc., parameters such as input channel gain, PEQ, compressor, and limiter are also determined.
Parameters such as phantom ON / OFF, gain, and PEQ are determined depending on the type of microphone used (SM58, C-414, CMC65, etc.).
Also, although not shown in this figure, the PEQ setting value (A operator is nervous for howling), the amplifier level adjustment value (B operator is set to lower the high range), etc. are determined by the operator. There is.
In addition, for each event type, the compressor and limiter setting values (compressor / limiter must be deepened / enhanced for music objects, and must be set on the safe side for C events) may be determined.
In this way, by searching the database 14 using an attribute as a key, it is possible to obtain signal processing data including a setting value and other know-how that are optimal for the attribute.

Processing when an event such as a concert is held using the acoustic setting support device of the present invention configured as described above will be described with reference to FIGS. In addition, although the case where an acoustic plan figure is output is demonstrated here, you may make it output an acoustic plan in formats other than a figure format as mentioned above.
FIG. 6 shows the entire processing when an event such as a concert is held.
When creating an acoustic plan diagram (S1 is YES), the process proceeds to an acoustic plan diagram creation process in step S2.
FIG. 7 is a flowchart showing the flow of the acoustic plan diagram creation process.
In the acoustic plan diagram creation processing, first, the computer 11 is used to access the database 14 to search whether acoustic plan data having an attribute corresponding to the event to be held this time is registered (S11). For example, it is searched whether there is acoustic plan data of the same type of event using the same facility.
When acoustic plan data that matches the search conditions is registered (YES in S12), the corresponding acoustic plan data is downloaded (S13), the downloaded acoustic plan data is corrected as necessary, and the current event A sound plan diagram is created and displayed or printed (S14).

On the other hand, when the acoustic plan data matching the conditions is not found (NO in step S12), the information regarding the acoustic equipment of the facility serving as the venue, and the acoustic plan corresponding to the venue or used acoustic adjustment console The template shown in the figure is acquired (S15). Then, while referring to the information about the downloaded equipment etc., create an acoustic plan that shows the assignment of microphones to each input channel and the assignment of speakers to each output channel, etc., and this time using the template of the downloaded acoustic plan diagram An acoustic plan diagram for the event to be created is created and output (S16).
An acoustic plan diagram having a common format is created by downloading an acoustic plan diagram template corresponding to a facility to be used as a venue or an acoustic adjustment table to be used from the database 14 and creating an acoustic plan diagram using the template. Will be able to. Note that the acoustic plan diagram template corresponding to each facility or the acoustic adjustment console to be used may be stored in the computer 11 in advance by a method other than downloading from the database 14.
In this way, for example, in the event held every year, the sound plan data used last year can be called for reference, or for the first time at the event, the contents set by other users in the past can be called for reference. Can do.

Returning to FIG. 6, when creating setting data to be set in the acoustic adjustment console (step S3 is YES), the acoustic adjustment console setting data creation processing in step S4 is executed.
FIG. 8 is a flowchart showing a flow of setting data creation processing of the acoustic adjustment console.
In the setting data creation processing of the acoustic adjustment console, first, attribute information relating to the event to be held is selected as a key, and signal processing data in the database 14 is searched (S21). At this time, not only the above-described event attribute information such as event type (opera, rock concert, lecture, etc.) but also information such as the type of instrument used and the type of microphone used as a key, the database 14. And whether or not there is signal processing data having similar conditions.
As a result, when signal processing data matching the search condition is found (YES in S22), the signal processing data is downloaded (S23) and set in the acoustic adjustment console 5 based on the downloaded signal processing data. Setting data is created (S24). That is, the downloaded signal processing data itself or the signal processing data modified as necessary is stored in the memory in the computer 11 as setting data to be set in the acoustic adjustment console 5.
For example, when a vocal microphone as an attribute is selected, almost the same value may be given as a preset for gain setting and EQ everywhere, but the degree of reverb may be quite different. Therefore, in step S23, not only can all the set values be called up, but also the setting that a set value of a certain parameter is not called up can be selected.

When there are a plurality of signal processing data matching the search condition in step S22, (1) a simple average value of the plurality of signal processing data is calculated. (2) signal processing data for a predetermined number of times from the newest one. (3) The weighted average is calculated by increasing the weighting of the most recent data, and the setting data of the acoustic adjustment console 5 may be obtained.
In the case of (2) and (3) above, it reflects changes in operation technology, changes in musicality with the passage of time, operator's proficiency level, aging / aging of facilities, etc. be able to.
Then, it is determined whether or not the creation of setting data has been completed for all the channels (S25). If not, the process returns to step S21 to further create setting data.

On the other hand, if there is no signal processing data matching the search condition (NO in S22), it is determined whether or not the search is further performed by changing the search condition (S26), and the search is performed again by changing the search condition. If so, the process returns to step S21.
Further, when the search condition is not changed (NO in S26), it is determined whether or not the setting data of the acoustic adjustment console 5 is created by the computer 11 using the control program (S27). Proceed to step S25.
When the setting data is created by the computer 11 (S27 is YES), the process proceeds to step S28, and as shown in FIG. 4, the setting data of the acoustic adjustment console 5 is created by using the control program. Store in memory. Then, the process proceeds to step S25.
In this way, setting data for the acoustic adjustment console 5 is created and stored in the memory of the computer 11.

  In the above description, when there is no data that matches the search condition, the search condition is changed and the search is performed again. Further, the signal processing having attribute information closest to the search condition from the database 14 is performed. Data may be obtained as a search result. For example, when the record that matches the input search condition does not exist in the database 14, the attribute information included in the record registered in the database 14 is stored in the server 13 connected to the database 14. Then, the degree of approximation with the search condition input from the computer 11 is calculated, and the record having the attribute information that is most approximated is selected and output as the search result. Thereby, even if it is a new operator, an event, etc., it becomes possible to set an optimal value efficiently using the data of the similar past operation conditions.

Returning to FIG. 6, when it is time to rehearse an event (S5 is YES), first, a microphone, an input channel, an output channel, and a speaker according to the acoustic plan diagram created in the acoustic plan diagram creation process of step S2 Various devices are set (S6). Then, the setting data created by the acoustic adjustment console setting data creation processing in step S4 is read from the memory of the computer 11, set in the acoustic adjustment console 5, and the initial setting of the acoustic adjustment console is performed (S7).
Then, the event or its rehearsal is started (S8).
Data (signal processing data) such as setting values of each controller of the acoustic adjustment console 5 is acquired for each of various stage conditions during the performance (for example, before the artist is changed), and the memory in the computer 11 is acquired. (S9). At this time, information indicating the acquired time and attribute information such as the name of the operator are also stored.
Then, after the performance is finished or at a desired timing, the acoustic plan data created in step S2 and the signal processing data obtained in step S9 are used as attribute information of the event (facility name, event name or type). And the date of the event, information indicating the time when the artist or performer appeared, information indicating the time when the signal processing data was acquired, and information such as the name of the operator) are registered in the database 14 (S10).
Thus, every time an event such as a performance is held, the sound plan data and signal processing data can be stored in the database 14 together with the attribute information of the event.

  In this way, every time an event is held, the acoustic plan data and various parameter data (signal processing data) used in the event are stored in the database 14 together with the attribute information of the event. When an event is held, it is not necessary to create a sound plan from a blank state by using the sound plan and signal processing data in the past holding, and initial setting of the sound adjustment console 5 is easily performed. be able to. By repeating the above processing, a more useful database can be constructed.

In the above description, the database 14 is accessed using the computer 11 connected to the acoustic system 1. However, the acoustic system 1 is provided with the same function as the computer 11. Also good.
In the above description, the acoustic plan data and the signal processing data are stored in the database 14 connected to the network. However, the present invention is not limited to this, and it may be stored in a simple mass storage device. Good.
