AI bass extractor. Follow the low end.
Bring a bass part out of a finished mix. Study the notes and phrasing, or use the remaining audio as a backing track for your own bass performance.

A focused approach
Hear the bass line beyond the kick drum
Bass is not simply every low-frequency sound in a song. Kick drums, low piano notes, and synthesizers may share that range. A bass extractor asks for the instrument as a source, so a description such as ‘The electric bass guitar’ is more useful than an instruction to keep all low frequencies.
Use Isolated sound to focus on the requested bass line. If your goal is to play bass over the song, audition Background audio instead. That output contains what remains after the target is separated, so it may serve as a practice mix with the bass reduced. Check the groove against the original before trusting either track.
From mix to source
How to use the bass extractor
Choose a useful recording
Upload an MP3, WAV, MP4, or MOV file no larger than 50 MiB (52.43 MB). Start with a source where the bass is audible; processing cannot guarantee recovery of a line buried beyond recognition.
Describe the bass timbre
Use ‘The electric bass guitar,’ ‘The upright bass,’ or ‘The synthesizer bass line’ as appropriate. The description should identify the instrument, rather than a broad frequency band.
Listen to the requested source
Open Isolated sound and compare the bass against the original. Check note beginnings, sustained notes, and the places where the bass plays with the kick.
Choose a study or backing track
Keep the isolated bass to learn the line, or keep Background audio to rehearse your own part. Download the chosen WAV and bring it into your preferred practice or editing setup.
Be specific about the sound
A prompt for the result you want
Describe the source, then choose the output that matches your goal. These are starting points to try with your own recording.
| Your goal | Try this prompt | Keep this track |
|---|---|---|
| Study an electric bass partListen for the instrument's attack as well as its low notes. | The electric bass guitar | Isolated sound |
| Make a bass practice mixCheck that the kick and other low instruments still feel usable. | The electric bass guitar | Background audio |
| Extract a synth bass lineChoose this when the low part is electronic, rather than a bass guitar. | The synthesizer bass line | Isolated sound |
Made for a real next step
Put the separated audio to work
Learn a bass line by ear
Focus on note changes, slides, and rhythmic placement. Return to the original mix when an extracted note is unclear instead of treating artifacts as part of the performance.
Practice with the band
Use the remaining track as a possible bass-reduced backing. Keep enough original context to hear the relationship between the bass and drums.
Study different bass sounds
Compare plucked, sustained, and synth-driven parts. Prompting for the actual source helps you ask for a bass instrument rather than every sound in the low end.
Listen before you commit
Three checks worth making
Compare a quiet passage and a busy passage with the original, at a similar listening level.
Pitch and sustain
Check the full length of a note. A bass attack may survive while its sustain fades or becomes uneven.
Kick bleed
Compare downbeats with the original. Percussive low-end bursts in the isolated bass may come from the kick.
Playback system
Use headphones or speakers that reproduce the bass clearly. A phone speaker can make it difficult to judge low notes and remaining bleed.
Know the limits
Separation quality depends on the mix
A dense low end, distorted bass, and instruments playing similar notes can make bass extraction harder. The result may include kick bleed, reduced sustain, or missing harmonics. It is an estimated source from the finished recording, not the original bass channel.
A bass-reduced backing can still contain traces of the part. If you need an exact bassless mix for a performance or production, original stems provide more control. Check permissions before reusing an extracted part outside your own authorized material.
Can I isolate bass from a song online?
Yes. Upload a supported file, describe the audible bass instrument, and audition Isolated sound. The quality depends on how clearly that source can be distinguished in the original mix.
How do I remove bass for a backing track?
Target the bass, then keep Background audio. Listen for remaining bass notes and changes to the kick or low keys before using the track for practice.
Can I extract upright bass or synth bass?
You can try prompts that match those sources, such as ‘The upright bass’ or ‘The synthesizer bass line.’ A prompt describes the target; it does not guarantee perfect separation from instruments with similar sounds.
Is this the same as using an equalizer?
No. An equalizer changes frequency ranges across the whole mix. Source separation attempts to identify a described instrument, which may contain both low fundamentals and higher harmonics.
Why does my isolated bass sound thin?
The source may have lost some sustain or frequency detail during separation, or your playback device may not reproduce the low end well. Compare at a similar level on suitable headphones, then try a more accurate description if needed.
