Music stems are individual audio files that represent specific instruments, vocals, or effect groups from a song. They give you detailed control during remixing or production.
Stem Splitter
WriteSongAI Stem Splitter is an AI stem separation tool for songs already in your WriteSongAI library. It splits a finished mix into separate instrument and vocal layers you can remix, rebalance, or import into a DAW for production.

What Are Music Stems? Families We Separate
A stem is an isolated layer from a full mix—vocals, drums, bass, and so on—so you can remix, rebalance, or study parts in a DAW. WriteSongAI keeps this inside your library workflow: generate a song, then split it when you need real multitrack control.
Each run can return up to twelve industry-standard stem families. Typical groups include:
- •Vocals — lead vocals (primary vocal performance)
- •Backing vocals — harmony and backing vocal layers
- •Drums — full drum kit and core drum bus
- •Percussion — auxiliary percussion separate from the main kit
- •Bass — electric bass, synth bass, and other low-end instruments
- •Guitar — electric, acoustic, and other guitar parts
- •Keys — piano, electric piano, organ, and other keyboard instruments
- •Synth — synthesizer pads, leads, and electronic layers
- •Strings — orchestral or section string parts
- •Brass — brass section and solo brass
- •Woodwinds — woodwind section and solo woodwinds
- •FX and ambience — effects, transitions, and atmospheric layers
Labels in your library may use shorter names (for example Vocals, Drums, Keyboard); they map to these stem families.
Twelve Stem Types, Twenty-Four Files: How Counts Work
You get up to twelve stem types and up to twenty-four audio files in one job. Types describe the musical role (vocals, drums, bass, keys, and more). The file count is higher because a dense mix may produce more than one file per family—such as doubled backing vocals or split percussion layers.
Every slot still gets a file. If a stem sounds empty or nearly silent, the original song likely did not contain that element; the exporter keeps the timeline consistent so your DAW session stays predictable.
Downloads: Lossless WAV and DAW-Ready Sync
- •Format and depth: each file is lossless WAV at 48 kHz and 24-bit (see the form note for how many files you receive per run).
- •Import into Ableton Live, Logic Pro, or any DAW that accepts WAV—no extra lossy compression step required before you mix.
- •Time alignment: all stems share the same start time (0:00), so one project lines up instantly for level balancing.
Pro Workflow: Full Multitrack Separation
Use Stem Splitter when a two-track vocal/instrumental split is not enough. One pass returns the full multitrack set, with extra files in the same family when the model splits fine layers (for example separate percussion elements). Pair it with Vocal Remover when you only need a quick karaoke-style split; open Stem Splitter when you are mixing for real in a DAW.
It allows you to:
- •Access individual instrument and vocal groups
- •Remix or rearrange music elements with finer control
- •Edit specific parts without affecting the whole mix
- •Import stems into DAWs (e.g. Ableton Live, Logic Pro) without another lossy compression stage
Ideal when you need maximum control over a song's components and pro-grade files for the rest of your workflow.

Create SongFrequently Asked Questions
Vocal Remover outputs two tracks: vocals and instrumental backing. Stem Splitter returns a full multitrack separation from your library song, with many separate files grouped by stem family instead of a single instrumental stem.
Each run targets up to twelve stem types and delivers up to twenty-four stem files. Multiple files can belong to the same stem family when the mix is split into finer layers.
Exports are lossless WAV at 48 kHz and 24-bit. Tracks are time-aligned so every stem starts at 0:00; import the set into a DAW (for example Ableton Live or Logic Pro) without manual lining-up or an extra lossy compression step before mixing.
Every stem slot is still exported, but a file only carries audible content when the original song actually contained that type of sound. If a part was not in the mix, the file may be silent or very quiet.
Yes. Files are standard WAVs you can open in common digital audio workstations for editing and mixing.
No. Stem separation runs automatically in your browser; production experience only matters for how you use the files afterward.
