Tīmeklistorchaudio implements feature extractions commonly used in the audio domain. They are available in torchaudio.functional and torchaudio.transforms. functional … TīmeklisUses may notice that there is tiny difference when they run two rounds of feature extraction including MFCC, Fbank and PLP. This is because the random signal-level ‘dithering’ used in the extraction process to prevent zeros in the filterbank energy computation. The corresponding code is 'Dither' function in file feature-window.cc.
