This function works in the way very similar to ``sox`` command, however there are slight differences. For example, ``sox`` command adds certain effects automatically (such as ``rate`` effect after ``speed`` and ``pitch`` and other effects), but this function does only applies the given effects. (Therefore, to actually apply ``speed`` effect, you also need to give ``rate`` effect with desired sampling rate.). Args: tensor (torch.Tensor): Input 2D CPU Tensor. sample_rate (int): Sample rate effects (List[List[str]]): List of effects. channels_first (bool, optional): Indicates if the input Tensor's dimension is `[channels, time]` or `[time, channels]` Returns: (Tensor, int): Resulting Tensor and sample rate. The resulting Tensor has the same ``dtype`` as the input Tensor, and the same channels order. The shape of the Tensor can be different based on the effects applied. Sample rate can also be different based on the effects applied. Example - Basic usage >>> >>> # Defines the effects to apply >>> effects = [ ... ['gain', '-n'], # normalises to 0dB ...

For example, ``sox`` commnad adds certain effects automatically (such as ``rate`` effect after ``speed``, ``pitch`` etc), but this function only applies the given effects. Therefore, to actually apply ``speed`` effect, you also need to give ``rate`` effect with desired sampling rate, because internally, ``speed`` effects only alter sampling rate and leave samples untouched. Args: path (path-like object): Source of audio data. effects (List[List[str]]): List of effects. normalize (bool, optional): When ``True``, this function converts the native sample type to ``float32``. Default: ``True``. If input file is integer WAV, giving ``False`` will change the resulting Tensor type to integer type. This argument has no effect for formats other than integer WAV type. 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): Override the format detection with the given format. Providing the argument might help when libsox can not infer the format from header or extension, Returns: (Tensor, int): Resulting Tensor and sample rate. If ``normalize=True``, the resulting Tensor is always ``float32`` type. If ``normalize=False`` and the input audio file is of integer WAV file, then the resulting Tensor has corresponding integer type. (Note 24 bit integer type is not supported) If ``channels_first=True``, the resulting Tensor has dimension `[channel, time]`, otherwise `[time, channel]`.
