It is provided for convenience, but we do recommend that you port your code to natively use ``torchcodec``'s ``AudioDecoder`` class for better performance: https://docs.pytorch.org/torchcodec/stable/generated/torchcodec.decoders.AudioDecoder. As of TorchAudio 2.9, :func:`~torchaudio.load` relies on :func:`~torchaudio.load_with_torchcodec`. Note that some parameters of :func:`~torchaudio.load`, like ``normalize``, ``buffer_size``, and ``backend``, are ignored by :func:`~torchaudio.load_with_torchcodec`. To install torchcodec, follow the instructions at https://github.com/pytorch/torchcodec#installing-torchcodec. Args: uri (path-like object or file-like object): Source of audio data. The following types are accepted: * ``path-like``: File path or URL. * ``file-like``: Object with ``read(size: int) -> bytes`` method. frame_offset (int, optional): Number of samples to skip before start reading data. num_frames (int, optional): Maximum number of samples to read. ``-1`` reads all the remaining samples, starting from ``frame_offset``. normalize (bool, optional): TorchCodec always returns normalized float32 samples. This parameter is ignored and a warning is issued if set to False. Default: ``True``. channels_first (bool, optional): When True, the returned Tensor has dimension `[channel, time]`. Otherwise, the returned Tensor's dimension is `[time, channel]`. format (str or None, optional): Format hint for the decoder. May not be supported by all TorchCodec decoders. (Default: ``None``) buffer_size (int, optional): Not used by TorchCodec AudioDecoder. Provided for API compatibility. backend (str or None, optional): Not used by TorchCodec AudioDecoder. Provided for API compatibility. Returns: (torch.Tensor, int): Resulting Tensor and sample rate. Always returns float32 tensors. If ``channels_first=True``, shape is `[channel, time]`, otherwise `[time, channel]`. Raises: ImportError: If torchcodec is not available. ValueError: If unsupported parameters are used. RuntimeError: If TorchCodec fails to decode the audio. Note: - TorchCodec always returns normalized float32 samples, so the ``normalize`` parameter has no effect. - The ``buffer_size`` and ``backend`` parameters are ignored. - Not all audio formats supported by torchaudio backends may be supported by TorchCodec. r) AudioDecoderz`TorchCodec is required for load_with_torchcodec.
