What changes when moving from 440Hz to 432Hz
HzVibe multiplies playback speed by 432/440. All frequencies and the tempo change by that ratio. The tool does not detect the file's original tuning; the preset assumes a 440Hz reference.

Questions
Does the 440Hz to 432Hz converter export a new file?
Yes. You can export a 16-bit PCM WAV in the browser. Files must be mono or stereo, at most 32 MiB, and at most 3 minutes long. Pitch and tempo change together.
Why does tempo change in this preview?
The current converter uses playback-rate retuning, so tempo shifts slightly along with pitch. That keeps the experience simple and fully client-side.
Does my track leave the browser when I test this conversion?
No. The selected file stays in the browser session and is not uploaded to a server.
