Stem Splitter

Stem splitting separates a mixed audio track into individual components (stems): vocals, drums, bass, and other instruments. This is invaluable for music production, remixing, sampling, transcription, and karaoke.

Demucs supports 2-stem (vocals + instruments), 4-stem (vocals, drums, bass, other), and 6-stem separation. Spleeter offers 2-stem and 5-stem (vocals, drums, bass, piano, other) separation.

Demucs (Meta AI) produces higher quality separation and is recommended for most use cases. Spleeter (Deezer) is faster and works well for quick separation tasks. For professional results, use Demucs.

Stem splitting costs a flat 5 credits per file processed, regardless of the number of stems or file duration. You receive all separated stems as individual audio files. Free users can try the tool with starter credits after signing up.

Upload files in MP3, WAV, FLAC, OGG, M4A, or WEBM format, up to 50MB. Stems are output as WAV files for maximum quality. Use our Audio Converter tool if you need the stems in a different format like MP3 or FLAC.

Processing typically takes 20-90 seconds depending on file length, quality, and the number of stems requested. A 4-minute MP3 with 4-stem separation usually completes in about 30 seconds. 6-stem separation takes slightly longer.

Yes. The separated stems are standard audio files (WAV) that import directly into any DAW including Ableton Live, FL Studio, Logic Pro, Pro Tools, and GarageBand. All stems maintain the original timing and length for easy alignment.

Yes. Upload your audio file to the stem splitting API endpoint with your API key and specify the number of stems (2, 4, or 6). The API returns a ZIP archive containing all separated stems. Ideal for music production platforms and DJ software integrations.

Popular uses include creating karaoke tracks (remove vocals), isolating drum patterns for sampling, extracting bass lines for remixes, practicing individual instrument parts, creating mashups by combining stems from different songs, and audio analysis for music education.

Yes. Demucs and Spleeter are trained on diverse music datasets and work across genres including pop, rock, hip-hop, electronic, jazz, classical, and more. Separation quality is generally highest for well-produced studio recordings with clear instrument separation in the mix.

Vocal removal separates a track into two parts: vocals and everything else (instrumental). Stem splitting goes further, separating into 4-6 individual parts: vocals, drums, bass, and other instruments. If you only need vocals and instrumental, vocal removal is simpler and sufficient.

Yes. After editing individual stems in your DAW (adjusting volume, adding effects, removing parts), you can mix them back together. This is the standard workflow for remixing — split into stems, process each stem independently, then mix down to a final track.
