Create natively linked STEMS in your Traktor collection. Works exactly like Traktor's built-in stem feature with automatic metadata sync. Batch processing for multiple tracks.

Uses best open-source algorithms for superior quality separation with better SDR scores than Traktor Pro 4.

New in 4.1.0 — Serato integration (alpha). Generate .serato-stems from your tracks and use them directly in Serato.

Optional AI method ensures the sum of all stems (drums, bass, other, vocals) equals the original mix for perfect DJing.

NVIDIA CUDA support or other DirectX 12 compatible GPU (FL 12.0+) on Windows (4GB+ VRAM) and Apple Silicon (M1/M2/etc.) on macOS for faster processing.

Everything runs locally on your computer. Unlimited processing. Your music stays on your computer.

Customize individual stem colors (drums, bass, other, vocals) for Traktor controllers and visual feedback.

Full support for Windows, macOS Apple Silicon, and macOS Intel with native performance optimizations.

Free tools to migrate .stem.m4a files (created in NUO-STEMS 4) to linked stems, extract individual stems from .stem.m4a/mp4, and change STEMS colors - no license required.

Already have a master and its stems? Pack them into a Traktor .stem.m4a. WAV, FLAC, AIFF or ALAC, checked to match to the sample. Free.

Export stems as separate .wav files (drums, bass, other, vocals) for use in Ableton Live, Logic Pro, and other DAWs.

Playlists, colors, hotcues, beatgrids, and all metadata automatically sync between originals and linked stems in Native TP4 mode.

Supports practically any audio file format (MP3, FLAC, ALAC, WAV, M4A, etc.). New formats added upon request.

Generate stems on your powerful gaming PC, then migrate them to your DJ laptop using Traktor Utilities.
