How to separate vocals, drums, and bass from a song

Start with a usable source

Use a song you own or have permission to process. Choose a clean export from the original recording when possible. A heavily compressed, distorted or reverberant mix gives the separator less clear information to work with. Renaming a file extension does not convert its audio format.

The picker accepts WAV, MP3, FLAC, M4A, AAC and OGG, but your browser must be able to decode the actual codec. If a file fails, export a PCM WAV from your audio software. Streaming-service links and protected downloads are not supported.

Choose the parts, then run the batch

1. Add one file or several files. The queue allows 20 tracks, 100 MiB per file and 300 MiB of source files in total. Each track must be ten minutes or shorter.
2. Select Vocals, Drums, Bass, Instruments, or All stems. Instruments means the remaining sounds such as guitar and keys; it does not include the bass or drums.
3. Select Separate tracks. The first run downloads an approximately 172 MiB model. Keep the page open while tracks process one after another.
4. Listen to each stem. Download individual 44.1 kHz WAV files, a track ZIP, or a ZIP of all completed tracks. Save results before navigating away.

Make a backing track without the vocal

Select Drums, Bass and Instruments. Import those three WAVs into separate Studio lanes and align their starts. Together they form an estimated non-vocal backing track. Downloading Instruments alone will omit the drum and bass parts.

Choosing fewer outputs reduces the amount of result audio retained in memory. It does not make the underlying model compute only those instruments. If results fill the 512 MiB output budget, download and clear completed tracks before continuing.

Listen for the limitations

These are estimates extracted from a finished mix, not the original recording-session tracks. Listen for vocal leakage, softened drum attacks, missing harmonics and watery tails. Check important passages against the full song instead of assuming a soloed artifact was played by the musician.

Desktop use is recommended. GPU acceleration is attempted where available, with a CPU fallback during initialization. CPU processing can be much slower than real time. No speed or perfect-isolation guarantee applies to every browser or track.
