@terminallyTestified Hi. The development team is aware of the synchronization issues with sound. I’m afraid this varies from computer to computer as some people report from 1 to 3 fps delay while others report as you 10 up to 20 fps.
We’ve found that using MP3 files causes issues with playback sync (like when you start to play from a different place on the timeline) so we’re advising to use WAV files instead. You can convert MP3 to WAV by using the free audio editor Audacity (http://audacityteam.org)
This will probably not reduce the lag by a big amount but it should help the playback to be a bit more “faithful”.
That said, if you want to add sound to your final animation, we suggest you only use sound in Pencil2D for rough timing purposes until this is fixed (ETA Pending), and use a video editor to finalize the sound tracks for your animation.
There are various free video editors we know of, so here’s a list:
