# config for high-resolution MFCC features, intended for neural network training.
  # Note: we keep all cepstra, so it has the same info as filterbank features,
  # but MFCC is more easily compressible (because less correlated) which is why
  # we prefer this method.
  --use-energy=false   # use average of log energy, not energy.
  --sample-frequency=16000 
  --num-mel-bins=40    
  --num-ceps=40   
  --low-freq=40    # low cutoff frequency for mel bins
  --high-freq=-400 # high cutoff frequently, relative to Nyquist of 8000 (=7600)
