Preview a 432Hz-to-440Hz playback-rate retune directly in the browser. This inverse comparison is useful when you want to move back toward standard concert pitch and hear the contrast immediately.
Hzvibe previews this shift by changing playback speed. That means the pitch moves toward 440Hz while tempo changes slightly too, which makes it useful for listening comparisons rather than final mastering.
The converter runs in the browser with no server upload. Choose a local file, press play, and compare the retuned preview while the shared analyzer and player stay in sync.
After listening to this direction, compare it with the inverse conversion or play a clean 440Hz tone in the generator to hear the target reference by itself.
