# 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.
