Thread Subject: creating a large wav file

Subject: creating a large wav file

Hello:
I would like to receive a cue about how to modify the
relevant audio .m files in order to receive audio signals
through the input line and to create a wav file, but without
using too much memory to hold the temporary data.
Presently you can record using wavrecord, but the output
goes to a variable.
Any hint will be appreciated; I suspect that people which
deals with instrumentation might have a ready made solution.
Regards
Carlos

You can use the soundcard support built into the Data
Acquisition Toolbox to process and store the data as it
comes in, and you can control the fidelity and bitdepth of
the recording to meet your storage needs.
