WebApr 5, 2024 · Below is an easy way this can be done. We clip the first 5 seconds of the audio file. start_sec = 0 end_sec = 5 wvfrm = wvfrm [:, start_sec*sr:end_sec*sr] wvfrm.shape [1] / sr. 5.0. Sample rate is simply the number of frames recorded per second. The waveform that torchaudio returns is a tensor of frames. WebAudio spectrograms have applications in signal analysis. For example, a spectrogram can help identify audio issues, such as low- or high-frequency noise, or short-impulse noises like clicks and pops, that may not be immediately obvious to the human ear. flavour in marathi
