432Hz Frequency Converter

Match songs to your frequency

Free · In‑App Purchases

432Hz Converter retunes your music from one reference pitch to another — most famously 440 Hz to 432 Hz — and to 528, 963 or any other pitch you choose. Convert a whole library, or retune a track live and A/B it against the original until it sounds right. TWO WAYS TO RETUNE • Batch converter — add files and retune everything at once. Every file keeps its tags and cover artwork. • Live player — hear the retune in real time, flip instantly between the original and the tuned pitch, and save the version you like. EVERY PITCH, NOT JUST 432 • 440 → 432 Hz (Verdi tuning) in one tap • Solfeggio presets: 174, 285, 396, 417, 528, 639, 741, 852 and 963 Hz • Standard & historical pitches: 415 (Baroque), 432, 435, 440 and 442 Hz • Or enter any source and target frequency, down to fine cents • Not sure what a track was tuned to? Auto-detect the source pitch (experimental!) BUILT FOR YOUR LIBRARY • Reads MP3, M4A, AAC, Ogg, FLAC and WAV — plus the audio from video files • Folder structure, metadata and artwork carried straight across • Non-destructive: your originals are opened read-only and never changed; new files are written safely and never overwrite an existing one Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.432hzconverter.com/privacy
