AISong Split Stems: Extract Every Instrument as a Separate Track for Full Production Control

Most finished audio files are a problem for producers. Everything is mixed down into a single stereo output — drums, bass, guitar, keys, and vocals all baked together into one file. If you want to work with any individual element, you need the original multitrack session. For AI-generated music, that session doesn’t exist.

AISong’s Split Stems feature solves this directly. Built into the ai song generator platform, it uses an intelligent AI separation engine to detect and extract every instrument in a track as its own individual audio file — giving producers, DJs, and mixing engineers the full multi-track flexibility of a real studio session, from a finished AI-generated song, without leaving the platform.

What Is Split Stems?

Split Stems is an AI-powered multi-track audio separation tool built into the AISong production suite. Unlike a standard vocal remover that outputs only two files, Split Stems intelligently identifies every distinct musical element in a track and delivers each one as a separate, independently downloadable file — giving producers and editors full component-level control over any recording.

The number of output stems is determines automatically by what the AI detects in the source material. A sparse acoustic arrangement may produce 4 stems; a densely layered electronic production can yield up to 12. Possible outputs include vocals, drums and percussion, bass, acoustic and electric guitar, keyboards and synthesizers, strings, orchestral elements, and any additional instrumentation present in the mix.

Each stem is delivered at the same quality level as the source track, ready to import into any professional DAW — including Ableton Live, Logic Pro X, FL Studio, Pro Tools, and GarageBand — with the same full commercial rights as the original generated track.

How to Use Split Stems in 3 Steps

Step 1 — Select Your Track

Open the Split Stems tool from the AISong navigation panel. Your music library loads automatically — all tracks generated on the platform are immediately available for processing without any file upload or format conversion required. Select the track you want to break apart.

For the best separation results, use tracks generated at model V4.5 or above. Higher quality source material gives the AI more precise frequency information to work with, which produces cleaner stems with less cross-bleed between channels.

Step 2 — AI Analysis and Separation

Click to begin stem splitting. The AI engine analyzes the track’s full frequency content, stereo imaging, transient patterns, and harmonic relationships to identify and isolate every distinct instrument. This is a more computationally intensive process than simple vocal removal — the engine is detecting an unknown number of instruments rather than separating two fixed categories — so processing typically takes 1 to 2 minutes.

Step 3 — Preview, Download, and Import

Listen to each individual stem in the built-in audio player to verify separation quality before downloading. Download stems individually or as a complete package. All files export in MP3 (all users) or lossless WAV (paid subscribers). Import directly into your DAW and organize as a standard multitrack session.

More Tools Inside AISong

Split Stems is one part of a complete nine-function production suite. The other tools inside the platform cover every stage of the music creation workflow.

Create — From Idea to Finished Song

• AI Music Generator: converts text prompts or lyrics into complete professionally mixed tracks across 30+ genres, with full commercial rights on every output
• AI Lyrics Generator: produces structured verse-chorus-bridge lyrics from any topic, keyword, or emotion — multiple versions generated simultaneously for comparison
• Text / Lyrics to Music: turns any existing text — a poem, brand message, or personal story — into a finished song with original melody, arrangement, and vocals
  

Separate — Vocals, Instrumentals, and Stems

• Vocal Remover: isolates vocals from instrumentals with 98% accuracy in under 60 seconds, outputting two clean files — a cappella vocals and pure instrumental backing track
  

Layer — Build Songs From What You Already Have

• Add Tracks: add AI vocals to an existing instrumental, or generate a backing arrangement around an existing vocal —the Audio Weight slider controls how tightly the new layer follows the source
  

Extend and Transform — Finish, Reshape, and Deliver

• AI Song Cover: transforms any track into an alternate vocal version using genre-specialized voices including pop, rock, R&B, and country
• Extend Song: adds seamless new material at any chosen timestamp using a visual waveform editor, matching the original key, tempo, and energy
• MP3 to WAV Converter: converts any track to lossless 44.1kHz WAV for professional studio, broadcast, and commercial distribution use
  

How These Tools Work Together

The real value of AISong is not any single feature — it’s how each tool connects into a continuous creative workflow that takes a project from first idea to finished, commercially licensed output without switching platforms.

• Start with the AI Music Generator or Text to Music to produce a base track from a prompt or existing lyrics
• Use Add Tracks to layer vocals onto a beat, or build a full arrangement around a recorded vocal performance
• Run the completed track through Vocal Remover for a fast instrumental separation, or into Split Stems when full multi-track control is required
• Import the extracted stems into your DAW for professional mixing, remixing, or re-arrangement
• Use Extend Song to hit a specific video duration or add a missing section — bridge, outro, or second verse
• Apply AI Song Cover to explore different vocal interpretations of the finished arrangement
• Export everything in lossless WAV when the project is ready for professional delivery, broadcast, or commercial distribution
  

Each tool feeds into the next, which means a project can move from blank page to finished song entirely within AISong — no extra subscriptions, no file re-uploading, no platform switching required.

Conclusion

Split Stems turns a finished AI-generated track into a full production asset. Instead of a single locked stereo file, you get individual instrument stems — each clean, each independently usable, and each immediately ready for professional DAW workflows.

For producers who want to use AI-generated music as raw material rather than a finished product, for DJs who need per-element control for live performance, and for anyone who needs the multi-track flexibility of a real studio session from an AI source — Split Stems delivers exactly that capability, inside the same platform where the music was created.
