Instrumental Extractor — FAQ

It pulls the instrumental track — drums, bass, melody, everything except vocals — out of any song you upload. Same Demucs source-separation model used by Moises, Splitter.ai, and PhonicMind, but free and unlimited.

We run Meta's Demucs (MIT license) on your MP3/WAV. It separates the audio into four stems — vocals, drums, bass, other — and we mix the three non-vocal stems back together. Output is a clean instrumental WAV.

MP3, WAV, M4A, FLAC, OGG, AIFF, and most other audio formats ffmpeg can decode. Max upload size is 50 MB (about 5 minutes of 128 kbps MP3 or 3 minutes of 320 kbps).

About 6-15 seconds per minute of audio on our A100. A typical 3-minute song extracts in 25-40 seconds end-to-end including upload + download.

Excellent on well-mixed studio tracks. Acceptable on dense pop / rock / hip-hop. Weaker on songs where the vocal sits very low in the mix or is heavily processed (heavy reverb, doubled vocals, vocoder). For those tracks, expect some residual vocal in the output.

Personal use (practice, sing-along, study) generally falls under fair use. Public performance, distribution, or commercial release of the extracted instrumental WITHOUT a mechanical or sync license is not allowed. You're responsible for how you use the output.

About 3,000 tokens per song, regardless of song length (it's per-request, not per-second, because Demucs is compute-heavy and we're budgeting for the worst-case 5-minute case). Free daily-pool tokens cover most users.

Yes — use /music/stem-splitter/ to get all four stems (vocals / drums / bass / other) as separate files in a ZIP, or /music/isolate-vocals/ to get just the acapella.

Same Demucs model, same quality. Moises charges $4/month for a small monthly quota. LALAL.AI and Splitter charge per-track. Free.ai is pay-with-tokens (or daily-free-pool), no monthly subscription, no upload caps.

WAV at 44.1 kHz, 16-bit stereo by default. MP3 download is also available via the format dropdown if you want a smaller file for sharing.

On the free tier one at a time. Signed-in users can queue multiple via /batch/ — drop a folder of MP3s, get back a folder of instrumentals. API is also available for bulk automation.

Yes — POST an audio file to /v1/audio/separate/ with `mode=instrumental`. Returns a job_id you poll for completion + the WAV URL when done. Docs at /api/.
