Turn a finished mix into four audio stems
A stem is a separated part of a song. This tool estimates four parts from a mixed recording: vocals, drums, bass and the remaining instruments. The other-instruments track can include guitar, piano, synths and effects; these are not split into individual instruments.
Use individual stems in your next project
Practise one instrument
Listen to the drum or bass track on its own to study its part. In an audio editor, combine the other stems to practise alongside the song.
Prepare music for a video
Keep a separated track or the complete instrumental in your creations, then choose the section you want to use in a rap video.
How to split a song into stems
1. Add a mixed recording
Choose a saved song or upload MP3 or WAV audio. The maximum input is 40 MB and 10 minutes.
2. Start four-track separation
Sign in, review the displayed credit quote and start the separation. One task produces all four stems.
3. Preview and export
Listen to each stem and download MP3 or WAV files. The full instrumental combines drums, bass and the other-instruments track.
Separated stems are estimates, not original recordings
Instruments that overlap in pitch or timing can bleed into other stems. Reverb and compressed recordings can also affect separation. Listen to the files before using them; a larger output file or WAV download does not guarantee better separation.
Stem splitter questions
How much does stem separation cost?
Stem separation costs 3 credits per started minute, with a minimum of one minute. The quote uses the actual audio length and is shown before you start; one task covers all its outputs. Credits are returned when a task is confirmed as failed. Downloads do not start another separation task.
Which audio formats does the stem splitter support?
Upload MP3 or WAV files up to 40 MB, and download each result as MP3 or WAV. Choose a good source recording: changing the output format cannot restore information missing from the input.
Are the stems the same as the original studio tracks?
No. They are estimated from the mixed audio. Some vocals or instruments may remain in another stem, especially with dense arrangements or strong effects. Listen to the results before editing or publishing them.
Is the other-instruments stem the full instrumental?
No. The other-instruments stem excludes vocals, drums and bass. The complete instrumental is a separate mix of drums, bass and other instruments. Both the four stems and that instrumental mix are available.
Where are my separated stems saved?
They are saved as private music in your account. You can return to My creations to access or manage them. Downloaded copies can be shared by you; they are not made public by this tool.
Can I split a full song?
Yes, up to 10 minutes and 40 MB. Processing time depends on the recording and service demand. Check the existing task for progress rather than creating a duplicate while it is still pending.
Can I use a separated stem in a rap video?
Yes. Choose the saved track in the rap video creator and select a clip within the supported video duration. Video creation has a separate credit quote; splitting a song does not automatically create a video.
