See the guide: Summary Operations > Generation of Summaries

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 in the outputted Summary.Value protobufs is generated based on the name, with a suffix depending on the max_outputs setting:

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

#### Args:

• name: A name for the generated node. Will also serve as a series name in TensorBoard.
• 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]
• family: Optional; if provided, used as the prefix of the summary tag name, which controls the tab name used for display on Tensorboard.

#### Returns:

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