MATLAB: Am I unable to obtain any output in the Command Window after I use the SOUND function in MATLAB 6.5 (R13) on Mac OS X 10.2.5

javamacMATLABsound

Why am I unable to obtain any output in the Command Window after I use the SOUND function in MATLAB 6.5 (R13) on Mac OS X 10.2.5?

If I run the example below on Mac 10.2.5:

load chirp
sound(y,Fs)
a=1
b=1

I can hear the sound but the values of "a" and "b" are not displayed in the Command Window until I perform an additional action – for example, hitting the Enter key or clicking the mouse.

The example above works fine on Mac OS X 10.2.4.

MATLAB: Does the SOUND function on MATLAB 6.5 (R13) for Linux produce poor quality sound

This bug has been fixed in MATLAB 7.3 (R2006b). For previous product releases, read below for any possible workarounds:

This issue exists in the sound quality generated by MATLAB 6.5 (R13) for Linux.

To workaround this issue, try the following:

1. Use the AUDIOPLAYER and AUDIORECORDER functions in MATLAB 7.0 (R14) and later versions to avoid this issue as follows:

load handel;
player = audioplayer(y, Fs);
play(player,[1 (get(player, 'SampleRate')*3)]);
stop(player);

For more information on the functions AUDIOPLAYER and AUDIORECORDER refer the links below:

http://www.mathworks.com/access/helpdesk/help/techdoc/ref/audioplayer.html

http://www.mathworks.com/access/helpdesk/help/techdoc/ref/audiorecorder.html

2. For releases previous to MATLAB 7.0 (R14), if the system is running MATLAB with Java Virtual Machine 1.3 or higher, try this as a possible workaround:

load handel;
p = com.mathworks.toolbox.audio.JavaAudioPlayer(y, Fs, 16);
p.play;
%p.stop;
%p.pause;
% etc.

Note that "y" must be scaled between the ranges of [-1 1] for the files to play clearly.

MATLAB: Does the printed/exported figure from MATLAB contain a large black rectangle

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

Apple's X11 software was released after MATLAB 6.5 (R13), and we were therefore unable to test MATLAB with this prior to shipping. MATLAB is not supported with Apple's X11 software.

MATLAB 6.5 is only supported to run with the XDarwin and OroborOSX versions with which it is shipped.
