AI stem splitter for iPhone

A stem is one isolated part of a song, like the vocals, the drums or the bass. VocalErase splits your tracks into stems with AI, so you can study, remix or practice with any part on its own.

Choose how many stems

Vocals + Instrumental — the classic two-way split, and it works with your free credits.
4 stems — vocals, drums, bass and other instruments.
6 stems — adds guitar and piano on top of the 4 stems. Piano separation is still experimental.

Every mode also gives you a ready-made instrumental. The credit cost of each mode is shown in the app before you start.

What people use stems for

Producers and remixers who need an acapella or a drum stem.
DJs preparing instrumentals and acapellas for a set.
Musicians learning guitar, bass or piano parts by ear.
Teachers and students analysing how a track is put together.
Creators making covers, mashups and karaoke tracks.

How it works

Pick a song from your iPhone and choose 2, 4 or 6 stems.
VocalErase separates it in the cloud with an AI model.
Preview each stem in the app, then download or share the ones you need as 320 kbps MP3 files.

Formats and limits

Works with MP3, WAV, FLAC, M4A and OGG files up to 50 MB and 8 minutes long. AI separation is not perfect: dense mixes can leave faint traces of one stem in another.

Pricing: credits, no subscription

One credit covers a vocals + instrumental split of a song up to 4 minutes; songs up to 8 minutes cost 2, and the 4- and 6-stem modes use more credits. New accounts start with free credits for the basic split, and any credit pack unlocks every mode. Credits never expire and failed jobs are refunded automatically.
