Vocal Remover and Stem Splitter
Separate a song into a vocal and an instrumental, or into 4, 6 or up to 12 stems, and choose the right mode for karaoke, remixing, practice or mastering.
Two tools take a finished stereo song apart. Both accept MP3, WAV, OGG, M4A, FLAC and AAC, and both keep tempo and key untouched, so every part drops back onto a timeline in sync.
Which tool to use
| You want | Use | You get |
|---|---|---|
| A karaoke track, or an a cappella for a remix | AI Vocal Remover | 2 files: the vocal and the instrumental |
| Drums, bass and other parts separately | AI Stem Splitter, 4-Stem Split | Vocals, drums, bass and other |
| Guitar and piano on their own as well | AI Stem Splitter, 6-Stem Split | The four above plus guitar and piano |
| Every part of a song generated here | AI Stem Splitter, All Detected Stems | Every stem found, up to 12 |
All Detected Stems is available for songs generated in Aimusicis. For an uploaded song, use the 4- or 6-stem mode.
Run a separation
- Open the tool and upload a song, or choose one from My Music. In the studio, a song's menu also offers Remove vocals and Split into stems for that song.
- For the stem splitter, select the mode before running.
- When it finishes, play each part on its own, then download the parts you need.
Separation draws credits per run, shown on the button before you start; see Credits and Plans.
Getting a cleaner result
- Start from the best source you have. A WAV or a high-bitrate file separates more cleanly than a heavily compressed MP3 or a recording from a phone speaker.
- Expect some bleed. Reverb and backing vocals are shared between parts, so a soloed stem can sound thin or carry a faint trace of another instrument. Played together, the parts recombine cleanly.
- Separate once, then edit. To rebalance a song, separate it, then layer the parts at the levels you want in the Audio Mixer.
What to do next
- Sing over the instrumental, or record a new take and mix it in.
- Use an isolated vocal as training audio for a voice model.
- Master the rebalanced mix with AI Mastering.
