# 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)
