From raw takes to usable sections

Import long multitrack recordings, find the parts that matter, and keep the audio on your own machine.

🎵

Automatic Segmentation

Finds songs, loops, and transitions in long recordings by reading musical structure instead of raw level changes.

Tempo, Key & Chord Detection

Per-segment BPM, key, and chord hints bring you back to the sections worth finishing.

🎧

Multitrack Timeline

See every track as a waveform. Solo, mute, trim, and audition sections in the desktop app.

🎭

Instrument Tagging

Track tags help you jump back to the bass part, vocal pass, or drum groove you want to keep.

🔌

Transient Detection

Snap edits to transients and beats when you cut loops and samples.

💻

Runs Locally

Your audio stays on your machine. STEMWORKS runs analysis locally and does not upload stems.

Three steps from recording to export

Import the folder, run analysis, and export the sections you want to keep.

Import your session

Point STEMWORKS at a folder of multitrack audio files from your DAW or recorder. It handles split files and stereo pairs and keeps the audio local.

Run the analysis engine

STEMWORKS finds sections, estimates tempo, key, and chords, maps active tracks, tags instruments, and builds waveform data for the timeline.

Explore and export

Review songs with BPM, key, and chord hints, audition segments, rate ideas, and export the best parts to Ableton Live, Logic Pro, FL Studio, Studio One, Bitwig, Pro Tools, or video editors.
