Want to hear just the bassline, solo the drums, or pull the vocal out of a track? You can isolate an instrument from a song for free using AI — no session files, no expensive software. This guide explains exactly what you can (and can’t) isolate, and how to do it.
The tool for the job is our free AI Stem Splitter: upload a song and it separates it into individual tracks in seconds. Here’s how.
How to isolate an instrument — step by step
- Upload the song to the AI Stem Splitter (MP3, WAV, M4A and more).
- Choose “Split into stems.” The AI separates the track into Vocals, Drums, Bass and Other.
- Download the part you want as an MP3 — the isolated instrument you’re after.
What you can isolate
Modern AI (the Demucs model) cleanly separates a song into four groups:
- Vocals — the lead (and most backing) vocals on their own.
- Drums — the full drum kit.
- Bass — the bassline.
- Other — everything else melodic: guitars, keys, synths, strings, brass.
An honest note: AI reliably isolates these four groups. It can’t perfectly pull a single guitar out from among other melodic instruments — those all land in the “Other” stem together. But for vocals, drums or bass on their own, the results are excellent, even from a mono file.
Pulling one instrument out of the “Other” stem
When your part shares the Other stem with guitars, keys and synths, classic mixing tricks can finish what AI started. Work on the Other stem, not the full song, so there’s less to fight.
- EQ around its range. Filter either side of the instrument’s frequency band and cut where competing parts sit, using the Online Equalizer.
- Use the stereo image. Parts are often panned apart. Listening to one channel, or splitting the stem into mid and side, can separate what EQ can’t. See our guide to mid-side EQ.
- Phase cancellation. Align two releases from the same master that differ by one part (a full mix and an official instrumental) and flip the polarity of one: what they share cancels, leaving the difference.
Just want the vocal or the instrumental?
If you only need the vocal removed (a karaoke instrumental) or the isolated acapella, the AI Vocal Remover gives you exactly those two tracks in one step. Making a backing track to sing over? See how to make a karaoke version of a song.
What to do with an isolated instrument
- Learn a part by ear — solo the bass or drums and play along.
- Sample it — lift a clean drum break or a vocal chop.
- Remix & mashup — combine parts from different songs.
- Transcribe — run an isolated vocal through AI Transcription for lyrics, or study a solo note-for-note.
Tips by instrument
- Guitar: rhythm guitars are often panned, so check each channel of the Other stem first. Solos usually sit louder than the parts underneath, making them the easiest guitar to follow.
- Bass: usually the most usable stem, since little else shares the lowest octaves (synth bass counts too). If it sounds thin on small speakers, the upper harmonics are the issue; how to EQ bass guitar shows where to look.
- Drums: the whole kit arrives together. A low-pass leaves mostly kick, a band around the snare’s body favours the snare, and a high-pass leaves cymbals.
- Piano: the hardest, as it overlaps guitars and synths. Intros and breakdowns where it plays alone give the cleanest audio to loop or transcribe.
Tips for the best separation
- Use a good source file. A high-bitrate track separates more cleanly than a low-quality rip.
- Clean it up afterwards. Polish a rough isolated part with the AI Audio Enhancer or shape it with the Online Equalizer.
- Respect copyright — isolating parts for practice or private remixing is common; clear licensing before any commercial release.
Cleaning up bleed in an isolated part
- Fix the gaps first. Bleed is most obvious where your instrument stops. Trim those sections or use a noise gate.
- Filter what doesn’t belong. A faint hi-hat in a bass stem sits far above the notes, so a low-pass removes it cleanly.
- Judge it in context. Artefacts obvious when soloed often vanish once other parts play.

Copyright & fair use
Isolating a part doesn’t change who owns it. Learning or playing along privately is generally treated as low-risk personal use. Publishing, streaming or selling anything containing the isolated audio (a remix, a sample, a play-along video) normally needs permission from the rights holders; see how to clear a sample. “Fair use” is a narrow, case-by-case US defence and other countries’ rules differ, so don’t rely on it for a release. This isn’t legal advice.
Frequently asked questions
How do I isolate an instrument from a song for free?
Upload the song to an AI stem splitter, split it into stems, and download the part you want. Our AI Stem Splitter isolates vocals, drums, bass and the rest free in seconds.
Can I isolate just the guitar (or one specific instrument)?
AI separates a song into Vocals, Drums, Bass and Other. Guitars, keys and synths share the “Other” stem, so a single instrument can’t be pulled out perfectly — but vocals, drums and bass isolate cleanly.
How do I isolate just the vocals?
Use the AI Vocal Remover for a clean acapella and instrumental in one step, or take the Vocals stem from the stem splitter.
Does it work on any song?
Yes, on most songs, mono or stereo. Well-mixed, higher-quality sources separate best.
Is the isolated audio good quality?
Yes — AI separation produces clean, usable tracks suitable for practice, sampling and remixing.
Can I isolate just the kick drum or snare?
Not as its own stem, but you can get close by filtering the Drums stem: a low-pass for the kick, or a band around the snare.
Why can I still hear drums in my isolated bass?
The kick and bass share the low end, so some kick often bleeds through. Gate the gaps between notes and make a gentle EQ cut where the kick punches.
