432Hz Converter retunes your music from one reference pitch to another — most famously 440 Hz to 432 Hz — and to 528, 963 or any pitch you choose. Batch-convert a whole library in the background, or retune a track live and A/B it against the original until it sounds right.

Features
Drag in files or an entire folder tree and retune everything at once, using every core on your computer. The output mirrors your original folder layout, and every file keeps its tags and cover artwork.
Hear the retune in real time, flip instantly between the original and the tuned pitch, and save the version you like.
440 → 432 Hz (Verdi tuning) in one click, the nine Solfeggio presets (528, 963…), Baroque 415 Hz, or any custom source and target down to fine cents — with auto-detect for the source pitch.
Reads MP3, M4A, AAC, Ogg, FLAC and WAV — plus the audio from video files. Folder structure, metadata and artwork are carried straight across.
Your originals are opened read-only and never changed; new files are written safely and never overwrite an existing one.

Why 432 Hz music
The standard 440 Hz tuning often used in western music can be seen as a rather arbitrary choice. Many classic concerts and philharmonic orchestras did — and still do — use other frequencies that better fit the character of their instruments.
Listeners of 432 Hz music report that it sounds better and feels more harmonic. There are also reports of positive effects of 432 Hz and 528 Hz music (see here for technical details and here for healing indications). Alternative frequencies are also very well suited for meditation, music therapy, and relaxation.
