MATLAB: Is the default playback mode for the WAVPLAY function different in the MATLAB help and the documentation in MATLAB 7.0.1 (R14SP1)

asyncdefaultdocdocumentationhelpMATLABsyncwavplay

The MATLAB help for the WAVPLAY function, which can be viewed using the command:

help wavplay

lists the default playback mode as "sync", whereas the documentation which can be viewed using the command:

doc wavplay

lists the default playback mode as "async".

This change has been incorporated into the documentation in Release 14 Service Pack 3 (R14SP3). For previous releases, read below for any additional information:

This is an error within the documentation for MATLAB 7.0.1 (R14SP1) in the WAVPLAY function reference.

The correct default playback mode is "sync", meaning that a call to the WAVPLAY function will not return until the wav has played in its entirety.

This problem has been fixed in MATLAB 7.0.1 (R14SP1). If you are using a previous version, read the following:

This has been verified as a bug in MATLAB in the way that the BEEP command is executed on certain operating systems.

If you are not able to hear the system beep when you use the beep command, the following solution can be used to make a sound on your machine.

NOTE: This will not solve the problem of other functions that use BEEP, but it will allow you to have sound in your own applications.

The workaround involves creating another function (called, for example, beep2) which will play a sine wave.

function beep2
% Play a sine wave
res = 22050;
len = 0.5 * res;
hz = 220;
sound( sin( hz*(2*pi*(0:len)/res) ), res);

MATLAB: Do the BEEP or ERROR functions in MATLAB not produce a beep sound

The BEEP and ERROR functions produce the default system sound. If you have configured Windows not to produce any sound, BEEP and ERROR will be silent.

Please go to Control Panel->Sound and Audio Devices->Sound and ensure that “Windows Default Beep” sound is enabled.
