/TensorFlow 2.4


Outputs a Summary protocol buffer with audio.

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 Tensor of type string. Scalar. Used to build the tag attribute of the summary values.
tensor A Tensor of type float32. 2-D of shape [batch_size, frames].
sample_rate A float. The sample rate of the signal in hertz.
max_outputs An optional int that is >= 1. Defaults to 3. Max number of batch elements to generate audio for.
name A name for the operation (optional).
A Tensor of type string.
