Decode a 16-bit PCM WAV file to a float tensor.



金坛期货配资The -32768 to 32767 signed 16-bit values will be scaled to -1.0 to 1.0 in float.

When desired_channels is set, if the input contains fewer channels than this then the last channel will be duplicated to give the requested number, else if the input has more channels than requested then the additional channels will be ignored.

金坛期货配资If desired_samples is set, then the audio will be cropped or padded with zeroes to the requested length.

金坛期货配资The first output contains a Tensor with the content of the audio samples. The lowest dimension will be the number of channels, and the second will be the number of samples. For example, a ten-sample-long stereo WAV file should give an output shape of [10, 2].


  • contents: A Tensor of type string. The WAV-encoded audio, usually from a file.
  • desired_channels: An optional int. Defaults to -1. Number of sample channels wanted.
  • desired_samples: An optional int. Defaults to -1. Length of audio requested.
  • name: A name for the operation (optional).


A tuple of Tensor金坛期货配资 objects (audio, sample_rate).

  • audio: A Tensor of type float32.
  • sample_rate: A Tensor of type int32.
