Web1 jun. 2024 · mfccs_speech1 = librosa.feature.mfcc(y=speech1, sr=16000, n_mfcc=13, hop_length=800, n_fft=1600) But my last question is how Librosa is deciding the size of FFT for calculation ??? Like in Matlab code we have to put manually FFT size according to our window size. Here we are not giving the size of FFT, it should be 2048(in powers of 2). Web13 okt. 2024 · The length of my sample is 90000 and n_fft = 1024, hop_length = 128. According to the formula, the resulting n_frame must be roughly = 696.
