WebSep 9, 2024 · In this paper, all audio datasets are 44.1 kHz mono wave files, and the dimension of Log-Mel spectrograms and MFCCs is 40 × 256 (T = 256, F = 40). The frame size is 40 ms and the overlapping frames are 50%. As shown in Table 2, the hyperparameters of the TFFS-CRNN model were enhanced with a random search strategy. … WebMel-scale spectrogram is a combination of Spectrogram and mel scale conversion. In torchaudio , there is a transform MelSpectrogram which is composed of Spectrogram and MelScale . waveform , sample_rate = get_speech_sample () n_fft = 1024 win_length = None hop_length = 512 n_mels = 128 mel_spectrogram = T .
