[Dspforum] Did anyone use octave instead of matlab?

[Alan Ding]

I can't seem to get the wavrecord function in MATLAB to record from Line-in instead of Mic-in.  What are you guys using?  Audacity only outputs as .wav, .mp3, and ogg vorbis format?  I was able to use the spectrum functionality and output the frequency data in log format as a .txt.
