python - Good sound libraries? -

-

i need take audio signal, , extract overlapping audio frames it. need convert these frequency data (fft stuff / spectrogram) , analyze frequency information.

for example, if have 1 minute mp3 file, want split file smaller files, 00:00.000 00:03.000, 00:00.010 00:03.010. need see frequency breakdown of each sub-file.

which programming languages have audio tools me this? there linux command-line tools use? bonus points node.js (yeah right) or haskell, i'm familiar with.

haskell:

http://hackage.haskell.org/package/hsndfile. it's math, i'd imagine, hmatrix , soforth.
