[Dspforum] Did anyone use octave instead of matlab?

[Nenad Uzunovic]

I use octave and audacity. 

You can set audacity to record *.mat files. Then just use load() in either octave or matlab.

In audacity you need to open preferences then default output format then select other and in a pop-up window find matlab/octave

Hope this helps.
