About FourThirtyTwo
FourThirtyTwo is a native iPhone and iPad app that retunes audio to 432 Hz — or any reference pitch you choose. Import a track, compare the original and retuned sound while it plays, then create a pitch-shifted copy you can keep, save, or share. Nothing is uploaded. There are no accounts, ads, analytics, or servers behind the app. ONE PURCHASE. NO SUBSCRIPTIONS Pay once for the app. There is no subscription and no in-app purchase required to unlock its audio tools. NATIVE, ON-DEVICE PERFORMANCE Built for iPhone and iPad with Apple’s native audio and interface frameworks. Processing stays on your device for responsive preview and conversion without an internet connection. LISTEN BEFORE YOU CONVERT Flip between original and retuned playback while the track plays. Scrub the waveform, skip around, and decide with your ears before creating a new file. SOURCE TUNING YOU CONTROL Each import begins with the standard A = 440 Hz assumption. Run on-device Auto-detect to analyse the recording’s reference pitch, re-run detection whenever you like, or override the source tuning by hand. ANY REFERENCE PITCH 432 Hz is the default, but the choice is yours: presets for 415 Hz (Baroque), 432 Hz, 440 Hz (ISO standard), 444 Hz, and 528 Hz — or enter any custom frequency from 300 to 600 Hz. MULTIPLE TRACKS AT ONCE Batch mode converts a folder or multi-file selection in one pass. Every track has its own source-tuning control, progress, estimate, and clean target-Hz filename.
