Stem Splitter AI - Free 6-Stem Audio Extractor | Guitariz Studio

Separate any song into 6 stems with Stem Splitter AI: vocals, drums, bass, guitar, piano, and other. High-quality AI stem extraction for music production.

How Stem Separation Works

Stem separation decomposes a finished stereo mix into its individual multi-track components. Guitariz Stem Separator utilizes Meta AI's open-source Demucs architecture—a hybrid time-domain and frequency-domain deep neural network trained on isolated multi-tracks to distinguish overlapping acoustic sources in dense mixes.

6-Stem Source Extraction

Unlike standard 2-stem tools, our full separation mode isolates up to 6 distinct stems:

  • Vocals: Clean lead vocals and harmonies isolated from instrumental backing.
  • Drums: Full percussive track including kick, snare, toms, and cymbals.
  • Bass: Isolated bass guitar and sub-bass synthesizers for bass transcribers.
  • Guitar: Electric and acoustic guitar layers separated from keys and synths.
  • Piano: Acoustic piano and electric keyboard tracks.
  • Other: Remaining synths, brass, strings, and ambient effects.

Privacy & Temporary Storage

Uploaded audio files are processed statelessly and temporary stem download bundles are purged automatically after processing finishes.
