PNCC features

If you want to change the PNCC parameters, the following parameters are supported.

def pncc(signal=audio_wave, n_fft=512, sr=16000, winlen=0.020, winstep=0.010,
         n_mels=128, n_pncc=13):
Parameter Description
signal the audio signal from which to compute features. Should be an (N, 1) array
n_fft the FFT size. Default is 512.
sr the samplerate of the signal we are working with.
winlen the length of the analysis window in seconds. Default is 0.020s.(25 milliseconds)
winstep the step between successive windows in seconds. Default is 0.010.(10 milliseconds)
n_mels the number of filters in the filterbank, default 128.
n_pncc the number of cepstrum to return, default 13.
