def audio_spectrogram(input, window_size, stride, magnitude_squared=False, name=None):
  r"""Produces a visualization of audio data over time.

  Spectrograms are a standard way of representing audio information as a series of
  slices of frequency information, one slice for each window of time. By joining
  these together into a sequence, they form a distinctive fingerprint of the sound
  over time.

  This op expects to receive audio data as an input, stored as floats in the range
  -1 to 1, together with a window width in samples, and a stride specifying how
  far to move the window between slices. From this it generates a three
  dimensional output. The first dimension is for the channels in the input, so a
  stereo audio input would have two here for example. The second dimension is time,
  with successive frequency slices. The third dimension has an amplitude value for
  each frequency during that time slice.

  This means the layout when converted and saved as an image is rotated 90 degrees
  clockwise from a typical spectrogram. Time is descending down the Y axis, and
  the frequency decreases from left to right.

  Each value in the result represents the square root of the sum of the real and
  imaginary parts of an FFT on the current window of samples. In this way, the
  lowest dimension represents the power of each frequency in the current window,
  and adjacent windows are concatenated in the next dimension.

  To get a more intuitive and visual look at what this operation does, you can run
  tensorflow/examples/wav_to_spectrogram to read in an audio file and save out the
  resulting spectrogram as a PNG image.

  Args:
    input: A `Tensor` of type `float32`. Float representation of audio data.
    window_size: An `int`.
      How wide the input window is in samples. For the highest efficiency
      this should be a power of two, but other values are accepted.
    stride: An `int`.
      How widely apart the center of adjacent sample windows should be.
    magnitude_squared: An optional `bool`. Defaults to `False`.
      Whether to return the squared magnitude or just the
      magnitude. Using squared magnitude can avoid extra calculations.
    name: A name for the operation (optional).

  Returns:
    A `Tensor` of type `float32`.
