Remove vocals from a song

AudioRinse runs a source-separation model in your browser: a neural network trained on thousands of songs to tell a voice from the instruments around it. It hears the singer wherever they sit in the mix, with their reverb and harmonies, and writes the vocals to one track. The instrumental is the song minus those vocals, so the two always add back up to the original, sample for sample.

Old vocal removers flipped one stereo channel against the other to cancel whatever sits in the middle. That takes the bass and the kick drum with the voice, and leaves any vocal recorded in stereo. A model doesn't depend on where the voice is panned, so the instrumental keeps its low end.

• Standard runs HTDemucs, Meta's open separation model (126 MB). It works on any computer, on the graphics chip through WebGPU where the browser has it and on the processor where it doesn't.
• Best runs Mel-Band RoFormer, a newer model (464 MB). On the MUSDB18 benchmark songs its vocals measured about 3 dB cleaner than Standard's and its instrumental about 2.7 dB cleaner: less of the voice left behind, fewer cymbals in the vocals. It takes about three times as long and needs a fast graphics chip, so the page offers it only where yours is.
• Try Standard first. If you hear the voice in the instrumental, the result screen offers to separate the song again in Best.

• Start from the best copy you have: a WAV, FLAC or high-bitrate MP3 separates more cleanly than a low-bitrate rip, whose artifacts the model can't tell from the voice.
• Reverb, delay and backing vocals belong to the voice and go with it. A long, loud reverb tail can leave a faint trace.
• An instrument that doubles the melody, like a synth lead or a sax playing along with the singer, may stay in the instrumental or come out partly in the vocals.

Karaoke and backing tracks, practising your instrument with the band, covers, DJ edits and remixes, or the acapella for a mashup. Separating a song doesn't change who owns it: use the stems for your own practice, or with the rights holder's permission when you publish.
