A stem splitter estimates the separate musical parts inside a finished recording. Keep Four stems selected above to get vocals, drums, bass and other instruments as individual tracks, plus Instrumental and Drumless mixes. These are estimated stems, not the original studio tracks used to make the recording.
What is in each stem?
- Vocals: the estimated voices, including backing vocals that the model assigns to them.
- Drums: the estimated percussion and rhythmic hits.
- Bass: the estimated bass part.
- Other: the remaining instruments together, including guitar, piano, strings and synths.
- Instrumental mix: the musical backing without the estimated vocal part.
- Drumless mix: the song without the estimated drum part, keeping vocals and other instruments.
Four stems and Drumless separations include all six tracks, with individual downloads and a ZIP. A free Vocals or Instrumental separation can return only those two tracks; every paid separation includes all six. Choose the output you need before starting. A ZIP with six files still contains four separated parts and two mixes, not six independently isolated instruments.
Isolate drums or make a drumless track
To hear only the drums, keep Four stems selected. After processing, choose Drums below the player, listen to a passage and use Download. The same controls let you isolate Bass, Vocals or Other. Your listening position stays in place when you switch tracks.
To play along without the drums, choose Drumless before starting, or find its preview and download under All tracks in your existing six-track result. The drumless practice guide explains how to use that backing. There is no need to separate the same file again just to hear its other included tracks.
For a vocal-free backing, use the Instrumental track under All tracks. The vocal remover guide explains changing its key for karaoke. To study a singer, use Vocals; isolating vocals does not separate a lead singer from backing singers or another voice in a duet.
Preview the balance, then download
Under All tracks, open Mix & download and press Play mix to hear the four stems together. Mute Vocals for a backing without it, or mute Drums to hear how the other parts carry the rhythm. Use each stem’s volume slider to change the balance. When it sounds right, choose Export mix, then Download mix WAV. This saves the whole track at its original speed and key, using the current mute and volume settings. Keep the tab visible while it exports.
Choose Download all tracks, then Save ZIP to get the four stems plus the Instrumental and Drumless mixes together. You can still download any track individually. The ZIP uses the format selected above the downloads and adds no song-credit charge. It keeps the original speed, key and levels. Keep this tab visible while it prepares; if your browser cannot make a ZIP, use the individual links.
In a digital audio workstation, import the four stems to separate tracks and align them at the same start time. They share the source recording’s timeline. Avoid adding Instrumental or Drumless on top of the four stems: those mixes already contain some of the same parts. Use the Ableton Live guide if you are working there, or choose your editor in the stem-separation guides.
The optional WAV mix uses your local WAV stems, or the MP3 stems of a cloud result, on your device. It preserves their timeline and stereo channels. If the combined signal would clip, the exporter lowers all parts equally and shows the reduction. Saving MP3 audio as WAV does not recover detail lost during MP3 encoding.
For practice, muting Drums can leave room to play along as a drummer; muting Bass can let you hear the harmonic instruments while you learn a bass line. For remix preparation, isolating the voice can give you a starting point for a new arrangement. For listening study, compare the bass and drum stems to hear how the groove is built. None of these uses turns an unlicensed recording into material you can publish freely.
Why a stem can contain sounds from another part
A mastered song is one combined waveform. The separator cannot return to the microphone or instrument tracks that created it. Instead, it uses patterns learned from music to estimate which sounds belong to which source. If a synth bass and a kick drum overlap in pitch and time, some of each can appear in the other stem. A distorted guitar and a voice can also share harmonics. Reverb can linger in more than one track.
Use the clearest source file you have permission to use. A higher-quality source may preserve details the model needs, but it cannot undo a mix where two sounds are inseparable. Preview the loudest chorus, a quiet passage and any solo you care about. If a stem has artifacts, an editor may help with small repairs; the model cannot promise perfect isolation.
File, time and rights limits
Audio inputs include MP3, WAV, FLAC, M4A and OGG, up to 80 MiB and 10 minutes. You can also choose MP4, MOV, WebM or MKV video up to 10 minutes. The page separates its sound; video output can put a chosen track back with the picture. WAV and MP3 downloads keep the original speed, key and levels. A WAV cannot restore detail missing from the source.
Download results before closing the tab. Uploaded audio and results stay private; access ends after one day and deletion follows automatically. Accounts manage song credits; they do not provide an online audio library. There is no public stem library or link-based import. Only upload audio you own or are allowed to process. If you want to release a remix or sample, make sure you have rights to the composition and the recording; separating them does not change those rights. The privacy and terms pages explain the handling and use rules.
For practice, the single-track player can also estimate BPM and a possible musical key from a short excerpt while it plays. Open Analyze a section & key, then Analyze this section. This analysis stays on your device; correct uncertain results yourself. It does not change the files you download.
To save the whole selected track with a different speed or key, open Practice a section, then Download with speed & key. Choose Export track, then Download WAV. It uses the native stem WAV for new results, runs on your device in supported browsers and uses no extra song credit. Loops are for playback; this export saves the whole track.
