PurePitch432

About

PurePitch432 shifts your Spotify and Apple Music streams from 440 Hz 
to 432 Hz in real time — directly in your browser, with no quality loss.

432 Hz is considered by many listeners, musicians, and researchers to 
be a more natural, harmonious tuning. Music played at 432 Hz often 
feels warmer, more relaxed, and easier on the ears.

HOW IT WORKS
PurePitch432 intercepts the audio stream of your streaming service and 
applies a precise pitch shift of -1.818% using a professional-grade 
AudioWorklet engine. The result: your music, retuned to natural 
frequency — instantly, with a single click.
