Documentation

What's included

  • Filter preemphasis, normalization, RMS calculation
  • Autocorrleation calculation
  • Laguerre root finding and polynomial division
  • Mel-Frequency Cepstral Coefficient (MFCC) calculation
  • Linear Predictive Coding (LPC) coefficient calculation
  • Formant path finder (McCandless algorithm, from Praat)
  • Pitch finding (Boersma autocorrelation method, from Praat)

Why is it broken?

Open an issue! There are many incomplete aspects to this library, as it is highly specialized to my personal projects. Once others begin using it, I expect that it will become more generalized.
