Extract, remix, and practise with barbershop learning tracks
F-Droid repository metadata
Track Exploder turns part-predominant barbershop learning tracks into the practice mix you need.
Load the tenor, lead, baritone, and bass files for a song. The app extracts the isolated voice from each stereo track, aligns the parts automatically, and gives you a four-part mixer.
Use Track Exploder to:
solo your part or leave it out to sing against the other voices
adjust each part's level, stereo position, channel, mute, and inclusion
preview the mix with per-part waveforms
slow practice audio to 0.5× without changing its pitch
save reusable mix presets
export one mix or generate several mixes in bulk
write WAV and FLAC files while preserving shared source tags
Publishers do not always place the song at exactly the same point in every part file. Track Exploder measures the set and corrects those offsets automatically while keeping spoken introductions and pitch pipes together. Each part's adjustment remains visible and can be fine-tuned manually.
All audio processing happens on your device. Track Exploder has no accounts, advertising, analytics, tracking, or servers, and it does not upload your music.
Track Exploder is free and open-source software released under the MIT License.

What’s new
No changes to the app. It no longer requests the Internet permission — Track Exploder does all its work on your device, and now says so.
How to install
Download the APK from the button at the top of this page.
Allow “Install unknown apps” for your browser or file manager only, not for every app.
Open the downloaded file and confirm the installation.
If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
