  r"""Processes a `Tensor` containing sampled audio with the number of channels

  and length of the audio specified by the dimensions of the `Tensor`. The
  audio is converted into a string that, when saved to disk, will be equivalent
  to the audio in the specified audio format.

  The input audio has one row of the tensor for each channel in the audio file.
  Each channel contains audio samples starting at the beginning of the audio and
  having `1/samples_per_second` time between them. The output file will contain
  all of the audio channels contained in the tensor.

  Args:
    sampled_audio: A `Tensor` of type `float32`.
      A rank 2 tensor containing all tracks of the audio. Dimension 0
      is time and dimension 1 is the channel.
    file_format: A `string`.
      A string describing the audio file format. This must be "wav".
    samples_per_second: An `int`.
      The number of samples per second that the audio should have.
    bits_per_second: An optional `int`. Defaults to `192000`.
      The approximate bitrate of the encoded audio file. This is
      ignored by the "wav" file format.
    name: A name for the operation (optional).

  Returns:
    A `Tensor` of type `string`. The binary audio file contents.
