Free Software
GNU Octave
install the package signal-1.0.7.tar.gz to get resample.m and other signal processing functions
resample.m in the newest version does not work - get older version from subversion
audio-1.1.1.tar.gz doesn't work on Windows - use playrec instread
- Octave-Forge - Extra packages for GNU Octave
- Playrec Multi-channel Matlab and Octave Audio
- Plotting from Octave with gnuplot (and to files)
- A frequency sweep using MATLAB
- FIR Digital Filter Design - mentions Octave and Mathlab
- MJ O'Donnell, Scholar, WiP, Digital Sound Modeling - here you can download mathlab demos
- Octave Programming Tutorial - From Wikibooks, the open-content textbooks collection
- MATLAB Programming/GNU Octave - From Wikibooks, the open-content textbooks collection
