WebTo load audio data, you can use torchaudio.load. This function accepts path-like object and file-like object. The returned value is a tuple of waveform ( Tensor) and sample rate ( int ). By default, the resulting tensor object has dtype=torch.float32 and its value range is normalized within [-1.0, 1.0]. WebThe aim of torchaudio is to apply PyTorch to the audio domain. By supporting PyTorch, torchaudio follows the same philosophy of providing strong GPU acceleration, having a focus on trainable features through the autograd system, and having consistent style (tensor names and dimension names).
