Notes:
Versions 16 and later
You cannot directly read an audio file found in a directory or in a sub-directory of the application. We advise you to read the audio files stored on the storage card (SysDirStorageCard to find out the path of storage card and SysStatusStorageCard to find out its name).
The audio file to read can also be included in the application via the generation wizard. To read it, all you have to do is 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>)

<Result>: Boolean

True if the sound was played,
False otherwise.

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.

Component : wd240obj.dll
