Audio analysis in Python

Some signal-analysis-related Python scripts:

  • Several different methods of estimating the frequency of a waveform
  • Peak detection for spectra
  • Measure total harmonic distortion plus noise of a sine wave (THD+N)
  • Apply an A-weighting filter to audio files

I’m sort of intending to combine them all into one eventually.
