Outputs a Summary protocol buffer with audio. (deprecated)

THIS FUNCTION IS DEPRECATED. It will be removed after 2016-11-30. Instructions for updating: Please switch to Note that uses the node name instead of the tag. This means that TensorFlow will automatically de-duplicate summary names based on the scope they are created in.

The summary has up to max_outputs summary values containing audio. The audio is built from tensor which must be 3-D with shape [batch_size, frames, channels] or 2-D with shape [batch_size, frames]. The values are assumed to be in the range of [-1.0, 1.0] with a sample rate of sample_rate.

The tag argument is a scalar Tensor of type string. It is used to build the tag of the summary values:

  • If max_outputs is 1, the summary value tag is 'tag/audio'.
  • If max_outputs is greater than 1, the summary value tags are generated sequentially as 'tag/audio/0', 'tag/audio/1', etc.


  • tag: A scalar Tensor of type string. Used to build the tag of the summary values.
  • tensor: A 3-D float32 Tensor of shape [batch_size, frames, channels] or a 2-D float32 Tensor of shape [batch_size, frames].
  • sample_rate: A Scalar float32 Tensor indicating the sample rate of the signal in hertz.
  • max_outputs: Max number of batch elements to generate audio for.
  • collections: Optional list of ops.GraphKeys. The collections to add the summary to. Defaults to [ops.GraphKeys.SUMMARIES]
  • name: A name for the operation (optional).


A scalar Tensor of type string. The serialized Summary protocol buffer.
