Full or relative name of file to play. This file can be:
    Remarks:
    <Option>: Optional integer constant
    Runtime mode of sound:
    soundWaitThe code is locked as long as the sound is not entirely played.
    soundLoopThe sound is played in a loop.
    Caution: The file to play must be found on disk and not in the library (WDL file).
    soundDefault
    (Default value)
    The code continues to run as soon as the sound is started.

    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.
    Remark: Until Windows 7, the sound is played on the inside speaker of the PC. From Windows 7, the sound is played on the sound card.
    <Frequency>: Unsigned integer
    Frequency of the sound in Hertz.
    Remark: For the versions earlier than Windows 7, only the audible frequencies can be used (between 37 and 32767).
    <Duration>: Unsigned integer
    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,
    • Versions 23 and later
      the direct indication of duration (1 s or 10 ms for example).
      New in version 23
      the direct indication of duration (1 s or 10 ms for example).

    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.
