Sound(<Name of WAV file> [, <Option>])

<Name of WAV file>: Character string (with quotes)

Full or relative name of file to play. This file can be:
a WAV file.
Versions 16 and later
an audio file corresponding to all the formats supported by the OS (wav, mp3, 3gp, ogg, etc.). A summary of the supported audio files is available from the following address: http://developer.android.com/guide/appendix/media-formats.html.
Remarks:
The wav files in 32-bit format are not supported by Android.
This parameter can correspond to a URL. In this case, it is necessary to add the INTERNET permission when generating the application.

Remarks:
Versions 16 and later
You cannot directly play an audio file in a directory or in a subdirectory of the application. It is recommended to play the audio files on the storage card (SysDirStorageCard to know the path of the storage card and SysStatusStorageCard to know its name).
The audio file to play can also be included in the application via the generation wizard. To play it, simply specify the file name (name + extension).
You cannot play a WAV file found in a HFSQL memo item.

Playing a sound of a given frequency during the requested time Hide the details

<Result> = Sound(<Frequency> , <Duration>)

Duration (in milliseconds) during which the sound is played. Caution: the sound is locking. This parameter can correspond to:
an integer corresponding to the number of milliseconds,
a Duration variable,

Remarks

Stopping a non-locking sound

A sound played in non-locking mode can be stopped by the following code, called on a user action for example (click, control modification, etc.):

Sound("")

Size of sound files

Using large WAV files may trigger several problems (not enough RAM to load the sound, system stopped depending on the Windows version, etc.). For large ".WAV" files (several dozen megabytes), we recommend that you use the MCI functions.

Locking sound

A sound is necessarily locking:

If the sound is stored in a WINDEV library (.WDL file).
If the sound comes from a binary memo.

Sound and component

Sound is a non-locking function by default. To use Sound in a component without locking the application, you must comply with the following constraints:

The file corresponding to the sound must not be found in the WDL or in the component.
The file corresponding to the sound must be found in the EXE directory of the application.
