Main Feature

Real-Time Audio Effects for YouTube

Apply audio effects while playing YouTube videos:

  • Pitch control
  • Real-time vocal removal
  • Vocal-only listening mode
  • Reverb
  • Reverb+
  • Filter
  • Chorus
  • Equalizer

Real-time vocal removal is available on supported 64-bit devices. It works while the app is visible on screen and automatically turns off in the background to keep playback stable.

Use Cases

Transpose can be used for:

  • Changing the key of YouTube songs for singing practice
  • Lowering or raising pitch for karaoke and cover practice
  • Removing vocals from YouTube videos
  • Listening to vocal-only tracks with vocal isolation
  • Creating an MR-like backing track during playback
  • Adding reverb and EQ to YouTube music
  • Practicing songs without exporting or converting audio
  • Real-time audio effects for musicians, singers, and language learners

Supported Devices

  • Android 7.1 or later
  • ARM64 Android device recommended
  • Real-time vocal removal is available on supported 64-bit devices
  • Recent mid-range or flagship devices are recommended for stable real-time vocal processing

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.
