Free Software

GNU Octave

• Octave - Wikipedia
• Octave homepage
• Octave download

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
