What's included
AI Stem Separation
Meta's HTDemucs neural network splits any song into 4 clean stems: vocals, drums, bass, and other instruments.
100% Private
The AI model runs entirely in your browser. No audio is uploaded to any server — ever.
4-Stem Output
Get vocals, drums, bass, and other instruments as separate tracks. Solo or mute any stem before downloading.
GPU Accelerated
WebGPU acceleration for fast processing. A 3-minute song processes in 15-30 seconds on modern hardware.
Preview & Mix
Listen to each stem individually or in combination before downloading. Solo and mute controls for every track.
Download All
Download all 4 stems as individual WAV files, or get them all in a single ZIP archive.
Who is this for?
Remixing & Mashups
Isolate individual stems to create remixes, mashups, and bootlegs. Layer vocals from one track over the instruments of another for unique combinations.
Drum Sampling
Extract drum tracks from any song for sampling and beat-making. Isolate kick patterns, hi-hat grooves, and fills from your favorite records.
Practice & Transcription
Solo any instrument to learn parts by ear. Isolate the bass line, guitar riff, or drum pattern and practice along at any speed.
Film & Video Scoring
Extract instrumental stems to use as soundtrack elements in video projects. Remove vocals for clean background music, or isolate drums for rhythmic scoring.
Vocal Isolation
Extract clean vocal tracks for acapella performances, vocal analysis, or creating vocal sample libraries from existing recordings.
Live Performance
Create custom backing tracks by muting specific stems. Remove the bass to play your own live, or keep just drums and vocals for acoustic arrangements.
Professional AI Stem Splitting — Free in Your Browser
Our stem splitter uses Meta's HTDemucs v4 neural network — the same AI architecture behind professional services like Splice, LALAL.AI, and iZotope RX. Unlike those tools, ours runs entirely in your browser using WebGPU acceleration. Your music files are never uploaded anywhere, making this the most private stem separation tool available. The AI model splits any song into four clean stems: vocals, drums, bass, and other instruments (guitars, synths, keys, strings). Each stem is exported as a lossless WAV file. Whether you're a producer, DJ, musician, or content creator, this tool gives you studio-grade stem separation at no cost.
What Is Stem Separation and How Does It Work?
Stem separation (also called source separation or demixing) is the process of breaking a mixed audio recording into its individual components. A typical song contains vocals layered with drums, bass, guitars, synthesizers, and other instruments — all mixed together into a single stereo file. AI stem separation uses deep learning to "unmix" this audio. The HTDemucs model was trained on thousands of professionally produced songs where the individual stems were available. It learned the spectral and temporal characteristics of each instrument type, and can now predict and reconstruct each stem from a mixed recording. The result is four separate, clean audio tracks that can be used independently.
Stem Splitter vs Vocal Remover — Which Should I Use?
Both tools use the same AI model (HTDemucs v4), but they produce different outputs. The Vocal Remover gives you two tracks: a clean instrumental and an isolated vocal. The Stem Splitter goes further, splitting the audio into four tracks: vocals, drums, bass, and other instruments. Use the Vocal Remover if you just need karaoke tracks or a quick instrumental. Use the Stem Splitter if you need individual instrument stems for remixing, sampling, transcription, or detailed audio work. The Stem Splitter takes slightly longer to process since it produces four outputs instead of two.
Frequently asked questions
What stems does the splitter produce?
Four stems: Vocals, Drums, Bass, and Other (guitars, synths, pianos, strings, and all other instruments). This is the standard 4-stem separation used by professional tools.
Is the Stem Splitter free?
Yes, completely free with no limits. No signup, no watermarks, no per-minute charges.
How is this different from the Vocal Remover?
The Vocal Remover gives you 2 outputs (vocals + instrumental). The Stem Splitter gives you 4 outputs (vocals + drums + bass + other instruments). Same AI model, more detailed separation.
