What is the problem you are facing?
WebTorrent is not used.
Audio is less data consuming than videos, but adding webtorrent can help in 2 cases (2 that I can think of):
- Podcast with many users in the first few hours/days after publication
- Long or lossless tracks
What are the possible drawbacks or issues with the requested changes?
The current protocol should still be available for APIs and 3rd party tools.
Here is the lib used by PeerTube : https://github.com/webtorrent/webtorrent
