auditok.signal.compute_average_channel_stereo

auditok.signal.compute_average_channel_stereo(data, sample_width)[source]

Compute and return average channel of stereo audio data. This function should be used when the number of channels is exactly 2 because in that case we can use standard audioop module which much faster then calling compute_average_channel().

Parameters:
  • data (bytes) – 2-channel audio data to mix down.
  • sample_width (int) – size in bytes of one audio sample (one channel considered).
Returns:

mono_audio – mixed down audio data.

Return type:

bytes
