The advantage of PyAV is that it bundles the FFmpeg libraries so there is no additional
system dependencies. FFmpeg does not need to be installed on the system.

However, the API is quite low-level so we need to manipulate audio frames directly.

    Args:
      input_file: Path to the input file or a file-like object.
      sampling_rate: Resample the audio to this sample rate.
      split_stereo: Return separate left and right channels.

    Returns:
      A float32 Numpy array.

      If `split_stereo` is enabled, the function returns a 2-tuple with the
      separated left and right channels.
