A real-time mobile YouTube pitch changer, vocal remover, reverb, EQ, and audio effects app for Android.
Transpose is an open-source Android mobile app that lets you change the key of YouTube videos, remove vocals, isolate vocals, add reverb, apply filters, and adjust equalizer settings directly during playback.
Use it as a YouTube pitch shifter, karaoke practice app, vocal remover, MR/backing track helper, or real-time audio effects player.
No export. No conversion. No separate audio editor.
Download the latest APK from GitHub Releases.

- Listening to vocal-only tracks with vocal isolation
- Creating an MR-like backing track during playback

Basic playback and general audio effects are lighter than vocal removal. Vocal removal is the most CPU-intensive feature and may vary depending on CPU performance, thermal state, and current system load.
