I need to take an audio signal, and extract overlapping audio frames from it. I then need to convert these to frequency data (FFT stuff / like a spectrogram) and analyze the frequency information.
For example, if I have a 1 minute mp3 file, I want split the file into smaller files, from 00:00.000 to 00:03.000, from 00:00.010 to 00:03.010. Then I need to see the frequency breakdown of each sub-file.
Which programming languages have good audio tools that could help me do this? Are there linux command-line tools I could use? Bonus points for Node.js (yeah right) or Haskell, which I'm most familiar with.
