baritoad

karaoke for the songs nobody made a karaoke version of.

drop in a song you have. baritoad turns the singer down, times the lyrics word by word, and puts them on your tv. friends pick songs from their phones. free, open source, and it all runs on your computer.

download

windows 10 or 11, 64-bit · mac with apple silicon (m1 or newer), macos 13.4 or later · linux later

the installers aren't signed yet. windows may warn you: more info → run anyway. on a mac, open baritoad once, then system settings → privacy & security → open anyway. the first start downloads about 2 GB of models. they run locally, on your computer.

it's not studio karaoke. sometimes you'll still hear a little of the original singer.

gpu or cpu

taking the vocals out is the slow part. a graphics card makes it a lot faster, but the cpu works too. one 3:15 song, start to finish:

	time
gpu (rtx 2080 super)	17 s
cpu only (i7-9700k)	1 min 54 s

that's with pasted lyrics. a song without lyrics takes longer, because baritoad transcribes it first. the gpu path uses directml, so it isn't tied to one brand of card, but we've only tried nvidia. if your card doesn't pass baritoad's quick check, it uses the cpu instead.

on a mac it uses the cpu for now. a 3:37 song with its lyrics found online took 2 min 39 s on an m1 pro.

privacy

no account, no telemetry, nothing uploaded. it only goes online for the models, lyrics lookups and links you ask for, and party mode (what the relay sees).
