About this app
Your music, retuned.
Attune plays your local music files and retunes them to 432 Hz in real time - the natural frequency that sounds softer, warmer, and more harmonious than the 440 Hz standard.
No streaming. No account. No tracking. Just your music, the way it was meant to sound.
FEATURES
π΅ 432 Hz Real-Time Retuning
Every song is pitch-shifted to 432 Hz on the fly. Toggle it on or off - hear the difference instantly.
π§ Custom C++ Audio Engine
Attune doesn't rely on generic Android audio processing. It runs its own native C++ engine with r8brain for sample-rate-accurate pitch shifting and Oboe for direct hardware output with minimal latency. The result: clean, artifact-free 432 Hz conversion that preserves the full quality of your files - from 16-bit MP3s to 24-bit FLACs.
π Gapless Playback
Tracks flow seamlessly into each other with click-free crossfades - no gaps, no interruptions. Handled entirely in the native engine for sample-accurate timing.
