[Dspforum] Did anyone use octave instead of matlab?

[Wenstrand, Doug S.]

Oh, I should also mention that if you choose to use another tool to save a wavefile, then matlab can just read that as well:
the function is wavread('filename') (right Joseph?) { I don't have matlab on this computer, so there is always the chance that I just said the function name wrong}

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.
