sound_recording

Dear Sirs
I plan to record sound by using a microphone. I have MATLAB 7.4 version. I use simulink-data acquisition toolbox. Sample rate is 8 Khz. I want to record sound for eight hours continously. However I can not record more than one hour because of memory allocation problem.
My question is that MATLAB writes data to RAM?
Can I manage write data to hard disk?

As I understand, yes, all the matlab variables in the workspace will be
stored in RAM (typically in contiguous memory locations for that vector).
I suggest that you should maybe have a while loop that periodically saves
the files to the hard disk and flushes unused variables. Consider
pre-allocating for speed.

try *wavwrite*

Read the matlab documentation.

Good luck,
