When trying to upload an uncompressed WAV file with floating point bitrate (32bit to be exact) an error occures stating that "You can only upload PCM (Pulse Code Modulation) WAV.". Floating point is not stricly PCM, but it's also uncompressed and doesn't involve any proprietary codecs.

Change 103402 had a related patch set uploaded by Michał Łazowik: Allow to upload WAV files with 32 bit float uncmopressed audio https://gerrit.wikimedia.org/r/103402
Change 103402 merged by jenkins-bot: Allow to upload WAV files with 32 bit float uncmopressed audio https://gerrit.wikimedia.org/r/103402
Merged, will be on commons in about a week and a half. Note, I don't think this is exhaustive for all possible uncompressed pcm wav audio.
