Abstract

PROBLEM TO BE SOLVED: To provide a device and a method for realizing highly flexible reproduction control in slide show reproduction.SOLUTION: In the reproduction control of a slide show to perform sound reproduction with image reproduction, selection and reproduction of a sound file that stores a silent sound enables a pseudo-halt processing of a reproduced sound. For example, in response to an input of an instruction to halt a reproduced sound, or in response to the arrival of the reproduced sound at an Out Time, reproduced-sound conversion processing is executed to convert the sound subject to reproduction to a silent sound. In addition, by referring to repeat reproduction setting information of the reproduced sound, repeated reproduction of the reproduced sound is executed if the repeated reproduction is set to be executed, or the reproduced-sound conversion processing is executed to convert the sound subject to reproduction to a silent sound in response to the arrival of the reproduced sound at an Out Time if the repeated reproduction is set not to be executed.

Description

  The present disclosure relates to an information processing apparatus, an information processing method, and a program. In particular, the present invention relates to an information processing apparatus, an information processing method, and a program for performing playback control of an image and sound in an image (slide) playback process.

As one form of image reproduction processing, there is a slide show in which a plurality of images (slides) are sequentially switched and displayed. In many cases, when reproducing an image (slide) by a slide show (also called a browsable slide show), a process of reproducing audio data such as music is performed.
Recently, a Blu-ray disc, that is, a BD (Blu-ray Disc) is widely used as a data recording medium. The data recorded on the BD is recorded in a BD format defined in advance, and reproduction according to the defined format is executed during reproduction.

Specifically, the following data is defined in the BD standard.
(A) a playlist file having a playlist for playback control that defines the playback order of the content;
(B) a clip file consisting of a clip AV stream file which is a content storage file storing AV stream data to be reproduced, and a clip information file having reproduction position information of the clip AV stream file,
These data are recorded on the BD, and at the time of reproduction, content reproduction using these data is executed.

Furthermore, as a playback control application corresponding to the BD standard, there is BD-J which is a playback program in Java (registered trademark) format.
Even when the slide show which is the continuous reproduction of the image (slide) is performed by applying the BD-J, it is necessary to perform reproduction according to the BD standard.
However, in the slide show reproduction using the BD-J according to the BD standard, there is a problem that processing such as user operation or stop of sound corresponding to a predetermined elapsed time cannot be performed.

Note that the following patent document is an example of a conventional technique disclosing slide show reproduction processing.
Japanese Patent Laid-Open No. 2007-173927 discloses that when playing a slide show with music, each image (slide) is associated with each music data, and the switching timing of the image (slide) according to the playback time of each music data. A configuration is disclosed in which when the music data is shorter than the standard, the image data is reproduced in a silent state and the music data is switched in accordance with the switching of the image (slide).

  In this process, a so-called image and music are switched and played back in synchronization. This configuration assumes that image data and music data are in a one-to-one correspondence and are played back automatically. For this reason, the user cannot perform processing such as stopping the sound at an arbitrary timing.

  Japanese Patent Laid-Open No. 2008-182718 discloses a browsable slide show (Browsable Slide Show) to which data recorded on a BD-ROM is applied. In this process using BD, it is necessary to use BD-J in order to switch audio in accordance with user operation. However, in the BD standard, an instruction to stop playback of asynchronous audio is not defined in the format. The process of stopping the sound in response to a user operation cannot be performed.

An image file (00000.m2ts) 402 storing image data corresponding to a plurality of slides,
A plurality of audio files (00001.m2ts to 0000n.m2ts) 403a, b, c,.
These data are used.
In addition, the JAR file is used for playlist file selection processing and other reproduction control.
An image file (00000.m2ts) 402 is a file in which still images to be displayed during slide show reproduction are recorded as moving image data having a certain length. Time corresponding to the display time of each image is recorded in the play list file (00000.mpls) 401 as a play item (PlayItem).

In the playlist file (00000.mpls) 401, playback control information for slide show playback is recorded. For example, it has still mode setting information set corresponding to each play item.
A play item whose still mode setting is “02” is automatically set to a reproduction stop state when the reproduction item reaches the reproduction end point position. That is, the display as a still image is continued.

This still mode is defined on the BD-ROM format, and is attribute information indicating whether or not to continue the still display of the displayed image.
The play item set to still mode = 00 does not continue the static display.
The play item set to still mode = 01 continues the static display for a finite time.
The play item set to still mode = 02 continues the static display for an infinite time.
Note that the display release when the static display is continued for an infinite time is by an explicit operation from the user.

As shown in FIG. 5, the playlist file (00000.mpls) 401 includes a play item for image control (= main path) and a sub path for sound control (= sup play item).
In the following explanation,
Play list storage data for image control is “play item”,
The playlist storage data for voice control is “sub-pass”,
Will be described.

As shown in FIG.
The play list file (00000.mpls) 401 includes a plurality of play items for image control, that is, play items 1, 2, 3,.
The play item 1 has reproduction control information of one image data [image 1 (Slide 1)] in an image file (00000.m2ts) 402 storing a plurality of images. The reproduction control information includes information indicating a reproduction start position (In Time) and a reproduction end position (Out Time) of the image file (00000.m2ts) 402. Information corresponding to the playback start time and playback end time of each image is recorded in the playback start point (In Time) and playback end point (Out Time). Specifically, a value corresponding to about 1 second in 45 kHz units is set.

  Similarly, play item 2 has reproduction control information of [image 2 (Slide 2)] in image file (00000.m2ts) 402, and play item 3 has [image 3 in image file (00000.m2ts) 402. (Slide3)], each play item has reproduction control information for each image, and reproduction control for each image is performed by each play item.

Further, the playlist file (00000.mpls) 401 stores a plurality of audio control sub-paths, that is, sub-paths 1, 2, 3,.
The sub path 1 includes reproduction control information of audio data of the audio file (00001.m2ts) 403a. The sub-bus also includes a playback start position (In Time) and a playback end position (Out Time) of the audio file (00001.m2ts) 403a.

  Similarly, the sub path 2 has the reproduction control information of the audio file (00002.m2ts) 403b. The sub path 3 has the reproduction control information of the audio file (00003.m2ts) 403c. Hereinafter, similarly, each sub path has reproduction control information for each audio file, and reproduction control for each audio is performed by each sub path.

  As shown in the play item 3 shown in the figure, it is possible to set a plurality of sub paths for one play item, and the play item and the sub path do not have to have a one-to-one correspondence.

[5. Specific examples of playback control information for playlist files applied to slide show playback]
Next, details of the reproduction control information included in the playlist file applied to the slide show reproduction process of the present disclosure will be described with reference to FIGS.

As shown in FIG. 6, the playlist file (00000.mpls) 401 contains
(1) Play item correspondence information 411,
(2) Subpath configuration information 412,
These pieces of information are recorded. These pieces of information are used as control information applied to slide show reproduction.

First, (1) play item correspondence information 411 will be described with reference to FIG.
The play item correspondence information 411 is data in which control information corresponding to each play item set as control information corresponding to each image (slide) displayed in the slide show reproduction is recorded.

As shown in FIG. 6, the following data is recorded for each play item.
(1) Play item identifier (play item ID)
(2) Clip information file identifier storing the image (slide) to be played (file name of the clip information file)
(3) Playback start point (In Time)
(4) Playback end point (Out Time)
(5) Reference subpath identifier (reference subpath ID)

  The playback start point (In Time) and playback end point (Out Time) correspond to the playback start point and end point of each image (slide) in the clip AV stream file of the image (slide) to be played back.

  The reference subpath identifier (reference subpath ID) is a subpath identifier (ID) that is reproduction control information corresponding to audio data that can be reproduced together with an image (slide) reproduced by a play item.

For example, in the example shown in FIG.
For the play item of play item ID = 1, reference sub-path ID = 1, 2,
For the play item with play item ID = 2, reference sub-path ID = 1, 3,
For the play item with play item ID = 3, reference sub-path ID = 1, 4,
For the play item with play item ID = 4, reference sub-path ID = 1, 5,
For the play item with play item ID = 5, reference sub-path ID = 1, 2,
These correspondence data are set.

The audio data that can be reproduced together with the image (for example, image 1) reproduced by the play item with the play item ID = 1 is audio data associated with sub path 1 and sub path 2 controlled by sub path 1 and sub path 2. It means that there is.
The audio data that can be reproduced together with the image (for example, image 2) reproduced by the play item with the play item ID = 2 means that the audio data is controlled by the sub path 1 and the sub path 3.
The same applies hereinafter.

FIG. 7 shows a setting example of a clip associated with each sub-path, that is, a clip AV stream file storing audio data.
As shown in FIG. 7, the following audio data files are associated with each sub-path.
Subpath 1: Audio file (00001.m2ts) storing silent audio
Subpath 2: Audio file storing BGM audio (00002.m2ts)
Subpath 3: Audio file storing Japanese text audio (00003.m2ts)
Subpath 4: Audio file storing English text audio (00004.m2ts)
Subpath 5: Audio file storing music 1 (00005.m2ts)

For example, audio data that can be reproduced together with an image (for example, image 1) reproduced by a play item of play item ID = 1 is
Silent sound whose playback is controlled by sub-path 1,
BGM audio controlled by subpath 2,
One of these voices.
The other play items 2 to 5 are also associated with a combination of a silent sound whose reproduction is controlled by the sub path 1 and a sound reproduced by any one of the sub paths 2 to 5.

FIG. 8 shows a data configuration example of “sub-path configuration information 412”, which is another registration data of the playlist file.
In this sub-path configuration information 412, information on each sub-path as a control information for audio data is recorded. Specifically, the following information is recorded for each sub-path.
(1) Subpath identifier (subpath ID)
(2) Clip information file identifier storing the audio data to be played (file name of clip information file)
(3) Playback start point (In Time)
(4) Playback end point (Out Time)
(5) Repeat flag

The repeat flag is a flag indicating setting information as to whether or not repeated reproduction (repeat reproduction) from the reproduction start point is performed again when the reproduction end point is reached. For example,
Repeat flag = 0, no repeat playback,
Repeat flag = 1 indicates repeat playback,
The flag is set as described above.
A playback sequence using this flag will be described later.

[6. Reproduction control data recorded in the reproduction control program and specific examples of reproduction control]
As described above, the slide show reproduction process is executed as a process using a playlist specified by, for example, BD-J.
Various information described with reference to FIGS. 5 to 8 is recorded in the playlist file, and processing using these pieces of information is performed.
Furthermore, control data to be applied to slide show playback is also recorded in XML data, for example, in a BD-J file as a playback control program. When the slide show is reproduced, a process referring to the XML data is executed.

A configuration example of control data recorded in a BD-J file and a specific reproduction control processing example will be described with reference to FIG.
As shown in FIG. 9, the BD-J file 501 includes
(1) Page correspondence basic information 511,
(2) Page corresponding link voice information 512,
For example, these data are recorded.
Note that (1) page correspondence basic information 511 is essential information, but (2) page correspondence link audio information 512 is optional information set as necessary.

First, a configuration example of (1) page correspondence basic information 511 will be described with reference to FIG.
A page corresponds to one image (slide) displayed on the display device 104.
That is, for example,
Page 1 = Image 1 (Slide 1),
Page 2 = Image 2 (Slide 2),
Page 3 = Image 3 (Slide 3),
:
Page n = image n (slide n),
This is the correspondence.

The page is information that can be specified by the user. For example, the user can determine the image (slide) to be displayed on the display device 1104 by inputting the page designation information by operating the operation means (remote controller) shown in FIG. Also, page feed and page return can be performed by a switch operation of the remote controller. For example, an image (slide) displayed on the display device 104 is sequentially switched by this user operation.
Note that the images (slides) displayed on the display device 104 are sequentially switched with the input of a page feed command by a user operation or the elapse of the reproduction time of each preset image (slide).

In the (1) page correspondence basic information 511 shown in FIG. 9, the following information corresponding to each page is recorded.
(A) Page number
(B) Play item identifier (c) Sub-path identifier (d) Sub-path repeat flag

(A) The page number is an identification number of each page.
(B) The play item identifier is an identifier of a play item that is control data of an image (slide) set corresponding to each page.
(C) The sub-path identifier is a sub-path identifier that is set for each page and is audio control data that starts automatic reproduction at the page display start time.
(D) The sub-path repeat flag is a flag indicating the voice repeat (repeated reproduction) setting corresponding to (c) the sub-path identifier registered as the correspondence data.
Repeat flag = 0, no repeat playback,
Repeat flag = 1 indicates repeat playback,
The flag is set as described above.

For example, when the user designates a display page using the operation means (remote controller) 103, the data processing unit of the information processing apparatus refers to the page correspondence basic information shown in FIG. 9 and plays that are set corresponding to the designated page information. A play item is selected according to the item identifier, and display of an image (slide) associated with the selected play item is started.
Further, a subpath is selected according to the subpath identifier set corresponding to the designated page information, and reproduction of audio data associated with the selected subpath is started.
When the audio data reproduction end point (Out Time) is reached, if the repeat flag is set to “with repeat setting”, the same audio data is repeatedly reproduced (repeat). When the repeat flag is set to “no repeat setting”, the reproduction of silent audio data is executed. This control sequence will be described later with reference to a flowchart.

In addition to (1) page correspondence basic information 511, (2) page correspondence link audio information 512 is recorded in the BD-J file 501. Note that (2) page-corresponding link audio information 512 is optional information set as necessary.
A data configuration example of the (2) page-corresponding link audio information 512 will be described with reference to FIG.

In (2) page corresponding link audio information 512 shown in FIG. 10, the following information corresponding to each page is recorded.
(A) Page number
(B) Voice link identifier (c) Voice link icon position information (d) Subpath identifier (e) Subpath repeat flag

(A) The page number is an identification number of each page.
(B) The voice link identifier is an identifier of a voice link icon displayed superimposed on an image (slide) corresponding to each page.
Note that the voice link icon is an icon that can be designated by a user operation (clicking or the like), and is an icon associated with a specific voice file.

[8. Processing sequence executed by information processing apparatus]
Next, a processing sequence executed by the information processing apparatus will be described with reference to flowcharts in FIG.

FIG. 14 is a flowchart for explaining basic processing in slide show reproduction processing.
In the following, processing according to each flow described below is executed in the data processing unit 201 of the information processing apparatus 101 shown in FIG. 2 according to a program (for example, BD-J) that predefines a processing sequence.

The flow shown in FIG. 14 is a flow for explaining the processing after the start of the slide show designation reproduction.
The playback of the slide show is selected by the playback control program (BD-J) to be applied to the playback of the slide show according to the input of the slide show playback designation command by the user, and further selected by the playback control program (BD-J). It is executed as a process using a playlist file for playback of a slide show.

As described with reference to FIGS. 6 to 8, the play item correspondence information 411 and the sub path configuration information 412 are recorded in the playlist file.
Further, as described with reference to FIGS. 9 and 10, the page correspondence basic information 511 and the page correspondence link audio information 512 are recorded in the reproduction control program (BD-J).

The process of each step of the flowchart shown in FIG. 14 will be described.
First, in step S101, the data processing unit of the information processing apparatus inputs a page switching command from the user.
This page switching command is issued by operating the operation means (remote controller) 103, for example. It is also possible to carry out by input processing such as operation information of the page transition icon in the display example shown in FIG.

When the page switching command is input, the data processing unit obtains a sub path ID corresponding to the reproduced audio after the page switching in step S102.
The acquisition of the sub path ID is performed as a process referring to the page correspondence basic information described above with reference to FIG.
This is performed as a process of acquiring the sub-path ID registered in the page correspondence basic information corresponding to the page ID after switching.

  Next, in step S103, the subpath ID corresponding to the reproduced audio before the page switching is compared with the subpath ID after the page switching acquired in step S102 to determine whether or not they match.

If they do not match, that is, if it is determined that subpath switching according to page switching is necessary, the process proceeds to step S104.
On the other hand, if they match, that is, if it is determined that it is not necessary to switch the sub path according to the page switching, the process proceeds to step S105.

When it is determined that the switching of the sub path according to the page switching is necessary and the process proceeds to step S104, the audio reproduction control using the sub path of the sub path ID acquired in step S102 is started.
That is, according to the page correspondence basic information described above with reference to FIG. 9, reproduction of the audio data of the audio file designated by the subpath with the subpath ID registered as the correspondence information of the page after switching is started. Thereafter, the process proceeds to step S105.

  In either case after the start of audio reproduction by the new sub-pass in step S104, or in the case where the audio reproduction process to which the same sub-path as the previous page is applied is continued due to No determination in step S103, Determine the repeat flag setting.

The playback audio repeat flag is determined with reference to the “sub-path repeat flag” recorded in any of the information in FIGS. As described above, the sub-path repeat flag is a flag indicating a voice repeat (repeated playback) setting.
Repeat flag = 0, no repeat playback,
Repeat flag = 1 indicates repeat playback,
The flag is set as described above.

If it is determined in step S105 that the repeat flag is set to repeat, the process proceeds to step S108, and the process of repeating (repeat) playback of the current playback sound is continued.
Note that this repeated reproduction can be stopped by inputting a voice stop command by the user. Or it is good also as a setting which stops a repeat reproduction | regeneration automatically according to the preset maximum repetition frequency.

On the other hand, if it is determined in step S105 that the repeat flag is set to no repeat, the process proceeds to step S106.
In step S106, reproduction switching to silent sound is executed at the position of the reproduction end point (Out Time) defined in the playlist file or at the position immediately before it.

That is, a process of switching to a sub path for switching the sub path and performing reproduction control of silent sound is performed.
As described above with reference to FIG. 7, one of the audio files (AV stream file) is set as a silent audio file. This is the audio file 403a of FIG. The sub path for reproducing the silent audio file 403a is sub path 1 in the setting shown in FIG.

As shown in the play item information 411 described with reference to FIG. 6, sub path ID = 1 is set as a sub path ID (reference sub path ID) for controlling an audio file that can be reproduced corresponding to all play items. Yes.
As described above, the silent sound can be reproduced in any period in which any image (slide) corresponding to each play item is displayed.

For example, when displaying an image (slide) corresponding to play item ID = 1, which is the first entry of the play item correspondence information 411 shown in FIG. The voice of subpath ID = 2 registered in (1) is reproduced (BGM voice in the example shown in FIG. 7).
This is defined by the page correspondence basic information 511 shown in FIG.

  If the repeat flag setting for the voice with the subpath ID = 2 is “with repeat”, the determination in step S105 of the flow shown in FIG. 14 is Yes, and the process proceeds to step S108, where the voice with the subpath ID = 2 (see FIG. In the example shown in FIG. 7, BGM sound) is reproduced repeatedly.

On the other hand, if the repeat flag setting for the voice with subpath ID = 2 is “no repeat”, the determination in step S105 of the flow shown in FIG. 14 is No, and the process proceeds to step S106, where the voice with subpath ID = 2 is set. The reproduction of the audio of subpath ID = 1 (silent audio as shown in FIG. 7) is started from (in the example shown in FIG. 7 the BGM audio).
The silent audio file is an audio file set in order to create a simulated state where sound output is stopped.

After the reproduction of the silent sound file in step S106 is started, the process proceeds to step S107.
In step S107, the silent sound is repeatedly reproduced in accordance with the setting of the repeat flag of the sub-path for which the reproduction control of the silent sound is necessary.
As a general rule, the setting of the sub-path for controlling the reproduction of silent sound is “with repeat”.

  As described above, in the information processing apparatus of the present disclosure, a silent audio file is set as one of the audio data files, and the silent audio file is included as one of the audio files that can be played back corresponding to each image (slide). It is configured.

For example, in the reproduction control according to the BD-ROM format, it is possible to switch the audio file controlled by the sub path, but there is a problem that the audio stop process controlled by the sub path cannot be performed.
For this reason, for example, at the time of slide show reproduction, the user has to always select and output BGM sound corresponding to the sub path associated with the play item while displaying the image (slide) corresponding to the play item, and the sound is stopped. Could not process.

  On the other hand, in the configuration of the present disclosure, a sound output stop state can be realized in a pseudo manner by setting a soundless sound file and switching the sound to the soundless sound file. As a result, the voice can be stopped by switching the voice file that can be executed as playback control according to the BD-ROM format.

Next, a voice stop processing sequence at an arbitrary timing by the user will be described with reference to the flow shown in FIG.
The flow shown in FIG. 15 is a process in which an image (slide) corresponding to a certain play item is displayed in the slide show reproduction, and the audio corresponding to the sub path set corresponding to the play item is being reproduced.

For example, the display process of the image (slide) corresponding to play item ID = 1, which is the first entry of the play item correspondence information 411 shown in FIG. 6, is executed, and the sub-path defined by the page correspondence basic information 511 shown in FIG. This is a state in which the audio of ID = 2 (BGM audio in the example shown in FIG. 7) is being reproduced.
In this state, in step S151 of the flow shown in FIG. 15, for example, an audio playback stop command is input by the operation of the operation means 103 by the user.

The data processing unit 201 of the information processing apparatus 101 performs a process of switching to silent sound in step S152 in response to the input detection of the reproduction stop command. This process is executed as a switching process from the sub-path for reproducing the currently playing BGM to the sub-path for reproducing the silent sound file.
By this sub-path switching process, reproduction of silent sound is started and a pseudo sound stop state is set.

After the reproduction of the silent sound file in step S152 is started, the process proceeds to step S153.
In step S153, the silent sound is repeatedly reproduced in accordance with the setting of the repeat flag of the sub-path for which the reproduction control of the silent sound is necessary.
As a general rule, the setting of the sub-path for controlling the reproduction of silent sound is “with repeat”.

  As shown in this flow, the user can perform a process similar to the stop of the reproduced sound by switching from the currently reproduced sound to the silent sound at an arbitrary timing.

Next, a playback audio switching process sequence by the user will be described with reference to the flow shown in FIG.
The flow shown in FIG. 16 is a flow for explaining the processing after the start of the slide show designation reproduction.
The process of each step of the flowchart shown in FIG. 16 will be described.
First, in step S201, the data processing unit of the information processing apparatus inputs a playback sound switching command by the user.
This voice switching command is performed by operating the operation means (remote controller) 103, for example.

When the voice switching command is input, the data processing unit obtains the sub path ID corresponding to the playback voice designated by the user in step S202.
Next, in step S203, the subpath ID corresponding to the reproduced sound before switching is compared with the subpath ID corresponding to the switched sound acquired in step S202 to determine whether or not they match.

If they do not match, that is, if it is determined that subpath switching is necessary, the process proceeds to step S204.
On the other hand, if they match, that is, if it is determined that switching of subpaths is unnecessary, the process proceeds to step S205.

  If it is determined that the subpath needs to be switched and the process proceeds to step S204, the audio reproduction control using the subpath having the subpath ID acquired in step S202 is started. Thereafter, the process proceeds to step S205.

  In either case after the start of audio reproduction by the new sub-pass in step S204 or when the audio reproduction process to which the same sub-path as the previous page is applied is continued due to No determination in step S203, Determine the repeat flag setting.

The playback audio repeat flag is determined with reference to the “sub-path repeat flag” recorded in any of the information in FIGS. As described above, the sub-path repeat flag is a flag indicating a voice repeat (repeated playback) setting.
Repeat flag = 0, no repeat playback,
Repeat flag = 1 indicates repeat playback,
The flag is set as described above.

If it is determined in step S205 that the repeat flag is set to repeat, the process proceeds to step S208, and the process of repeating (repeat) playing the current playback sound is continued.
Note that this repeated reproduction can be stopped by inputting a voice stop command by the user. Or it is good also as a setting which stops a repeat reproduction | regeneration automatically according to the preset maximum repetition frequency.

On the other hand, if it is determined in step S205 that the repeat flag is set to no repeat, the process proceeds to step S206.
In step S206, playback switching to silent sound is executed at the position of the playback end point (Out Time) defined in the playlist file, or at the position immediately preceding it.

That is, a process of switching to a sub path for switching the sub path and performing reproduction control of silent sound is performed.
As described above with reference to FIG. 7, one of the audio files (AV stream file) is set as a silent audio file. This is the audio file 403a of FIG. The sub path for reproducing the silent audio file 403a is sub path 1 in the setting shown in FIG.

As shown in the play item information 411 described with reference to FIG. 6, sub path ID = 1 is set as a sub path ID (reference sub path ID) for controlling an audio file that can be reproduced corresponding to all play items. Yes.
As described above, the silent sound can be reproduced in any period in which any image (slide) corresponding to each play item is displayed.

In step S206, switching to a sub-path for controlling reproduction of silent sound is performed to start reproduction of silent sound, and the process proceeds to step S207.
In step S207, silent sound repeat (repeat) playback is performed in accordance with the setting of the repeat flag for the sub-pass that is required to control the playback of the silent sound.
As a general rule, the setting of the sub-path for controlling the reproduction of silent sound is “with repeat”.

In the process according to the flowchart shown in FIG. 16, the user can realize a pseudo sound stop process by switching to the silent sound when the reproduction sound can be switched at an arbitrary timing.
In this way, by setting a silent sound file and performing a switching process to the silent sound file, it is possible to realize a process similar to the playback sound stop process.
