def METHOD_NAME(audio, file_format=None, samples_per_second=None):
  """Creates an op that encodes an audio file using sampled audio from a tensor.
  Args:
    audio: A rank-2 `Tensor` that has time along dimension 0 and
        channels along dimension 1. Dimension 0 is `samples_per_second *
        length_in_seconds` long.
    file_format: The type of file to encode, as a string or rank-0
        string tensor. "wav" is the only supported format.
    samples_per_second: The number of samples in the audio tensor per
        second of audio, as an `int` or rank-0 `int32` tensor.
  Returns:
    A scalar tensor that contains the encoded audio in the specified file
    format.
