432Hz to 440Hz Converter

Preview 432 to 440 Hz retuning. Your audio stays on this device.

What changes when moving from 432Hz to 440Hz

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

How this 432Hz to 440Hz preview works

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.

What to compare next

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.

Questions

Does the 432Hz to 440Hz 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.
