nnAudio.Spectrogram

Module containing all the spectrogram classes

Classes

CQT	An abbreviation for CQT1992v2().
CQT1992	This alogrithm uses the method proposed in [1].
CQT1992v2	This function is to calculate the CQT of the input signal.
CQT2010	This algorithm is using the resampling method proposed in [1].
CQT2010v2	This function is to calculate the CQT of the input signal.
DFT	Experimental feature before torch.fft was made avaliable.
Griffin_Lim	Converting Magnitude spectrograms back to waveforms based on the “fast Griffin-Lim”[1].
MFCC	This function is to calculate the Mel-frequency cepstral coefficients (MFCCs) of the input signal.
MelSpectrogram	This function is to calculate the Melspectrogram of the input signal.
STFT	This function is to calculate the short-time Fourier transform (STFT) of the input signal.
iSTFT	This class is to convert spectrograms back to waveforms.
