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)

pcm input on mp3 encoder

does anyone know how a PCM input is partitioned in a mp3 encoder? I already know that each input is a small part of the original wave and inside the encoder it's divided in 32 smaller parts and so forth, but what is the size of this initial input?
