Questions tagged [wave]

This tag is for questions about the Python module wave - for working with the .wav sound format. FOR GENERAL WAV QUESTIONS, not related to Python, please use the [wav] tag.

The wave module provides a convenient interface to the WAV sound format. It does not support compression/decompression, but it does support mono/stereo.

It's recommended to use this tag in connection with , due to the colloquial meaning of wave (ex. in math or physics)
