I want to create 32bit float WAV files in Python (2.x). While "standard" WAV files usually use int, many professional audio applications process (and save) audio data as float. The standard wave module is not capable to do this: http://bugs.python.org/issue16525 Has anyone achieved this without using patched modules ? tnx for any help. python audio WebMar 27, 2024 · Nowadays, using 32bit float is pretty standard. For obvious reasons, avoid 8bit. 32bit signed doesn't provide better benefits than the float counterpart. Gsm should be avoided, as g721. In any case, remember that "WAV" is actually a container, while most .wav files are uncompressed, it is technically not "a format".
