Need help?

Separation is slow or seems stuck.

Processing time depends on audio length and the connection. Keep the page open and check your internet connection.

I can't download my audio.

Check your browser's downloads and any blocked-download notice. If MP3 export fails, try WAV.

What is the free allowance?

You can separate 2 songs and 10 minutes total per day for free. The allowance resets at midnight in Korea (UTC+9).

I can't upload a file.

MP3, WAV, M4A and FLAC are supported, up to 50 MB and 10 minutes per file. If the file can't be read, try converting it to MP3 or WAV.

How it works

How do I listen to only music or vocals?

Use the power button on the left of each track to mute or unmute it. Both tracks play together when both are enabled.

How do I change BPM and pitch?

Open Speed to adjust the speed ratio or target BPM. Use the − and + buttons under Key to adjust pitch in semitones. The BPM and key shown above the tracks are automatic estimates.

Do downloads include my edits?

Downloads include volume, speed, pitch, fades, cuts and pasted audio. Selecting a section alone doesn't export only that section. Mix combines the enabled tracks.

Will refreshing lose my results?

Keep the page open during separation. Completed edits are restored when you refresh the same tab. Opening the site again starts at the home screen. Deleting browser site data removes saved work.

I can still hear some vocals or instruments.

AI separation may leave some reverb, backing vocals or overlapping sounds, depending on the audio.
