I am trying to save content of alsa buffer to file for playing it in
Matlab.I choose Matlab for prototyping. I run full duplex ALSA based on code
http://www.bel.fi/~alankila/blog/2005/08/21/Full Duplex

I run alsa on Beagleboard. I want to save buffer content to a file, but it
failed with error: Segmentation fault when reach fclose(fp).
I want to know what kind of data that ALSA processes so I can implement my
LPC vocoder.

Thank you.

Best regards,
