Spleeter separates a mixed audio track into stems - vocals, drums, bass, and other instruments - each as its own audio file. Upload an MP3 or WAV and Spleeter returns 4 separate stem files you can remix or mute.

MP3, WAV, FLAC, M4A, OGG up to 50 MB. Stereo input gives the cleanest results; mono is upscaled to stereo before processing.
Spleeter runs on our GPUs against your daily free pool first; $5 → 200,000 paid tokens. About ~1,000 tokens per minute of audio.
Yes - extract the stems, then download "drums + bass + other" stitched together for an instrumental, or download "vocals" alone for an a-cappella. The form above has a one-click "instrumental" output.
Yes - separation does not alter timing or pitch. Stems align frame-for-frame with the source so they remix cleanly.
Yes - /batch/ accepts a folder of audio files. Each output (4 stems per source) lands in /account/?tab=history. For folder-tree preservation use the API.
Yes. POST your audio to /v1/music/separate/ and you get one download URL per stem back. /api/ has the full reference, including the model id to send.
You need rights to the source audio (your own recording, licensed material, or a song with explicit remix permission). Free.ai cannot grant rights to material you do not own; separating a chart pop song does not legalize publishing the stems.
WAV by default (lossless, ready to remix). MP3 is available in the format picker for smaller downloads.
Real-time factor is roughly 0.1-0.3× - a 4-minute song separates in 30-80 seconds. Use the queue button to close the tab.
