@EricZhang456 @james We can't say we're surprised, but the lag is quite evident.
If you were to try Tenacity, there wouldn't be much of a difference. Perhaps by Tenacity 2.0 we will have hardware accelerated rendering, but that's quite far from now...
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.
You can find out more about PeerTube at https://fedi.tips/peertube-video-hosting-on-the-fediverse/
