PeerTube, the Fediverse's alternative to YouTube, is normally associated with video. However, you can also upload audio files directly to PeerTube. It will accept lots of audio formats including .mp3, .ogg, .aac, .flac, .wma etc.
You can optionally upload an image file as a thumbnail. If not, audio files will show a black screen by default.

Any sense of how PeerTube intends to handle takedown notices?
Each server is totally independent, legally and technically. It's up to each individual server's owner to comply with legal requirements in their country.

understood - we just thought you might have discussed it with them
