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.

What Does "Stem Splitter" Mean?
Stems are separated audio parts taken from a full mix. They give you more control when you want to remix, rebalance, study, or reuse a song in a DAW or alongside other WriteSongAI tools as the product grows.
WriteSongAI Stem Splitter targets up to twelve industry-standard stem types:
- •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 Stem Files
Each song separation is built around up to twelve stem types. The tool delivers up to twenty-four separate stem files. The file count is higher than the type count because complex mixes are split into more than one file per family—for example several percussion layers or backing-vocal doubles.
Each stem file is always created for its slot, but it only contains meaningful audio when the original track actually had that kind of sound. If a stem type was not present in the source mix, the corresponding file may be silent or nearly silent.

What Files Will You Get?
- •Up to twenty-four downloadable stem files aligned to twelve stem families
- •Clean, high-quality audio suitable for remixing and production
- •Tracks you can loop, mute, or balance before further mixing

Professional Multi-Track Separation
Stem Splitter is the full separation workflow inside WriteSongAI when a simple vocal-and-instrumental split is not enough. One separation pass targets up to twelve stem types and returns up to twenty-four stem files, including multiple files for the same family when the model splits fine layers (for example different percussion elements).
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 and production workflows
This tool is ideal when you need maximum control over a song's components.
