How to use it

FAQ

What does the app actually do?

It detects the real tuning of the audio file you pick. If the file is already within about two cents of A=432Hz, it copies it untouched. Otherwise it pitch-shifts the audio so A=432Hz, and saves the result back to Files.

Which formats are supported?

Input and output: WAV, MP3, M4A. Mono and stereo. 44.1 kHz and 48 kHz.

Does it work offline?

Yes. The app makes no network requests. Everything runs on your device.

Is there a subscription?

No. One-time purchase. No in-app purchases, no ads, no accounts.

How do I get a refund?

Refunds are handled by Apple, not by us. Go to reportaproblem.apple.com, sign in with your Apple Account, and request a refund for the purchase.

The converted file sounds the same. Why?

If the original was already tuned within about two cents of A=432Hz, the app copies it untouched on purpose, to avoid pointless processing. The result is identical to the source.

The detected pitch looks wrong. What happened?

Very short clips, heavily processed audio, or files that are not music can confuse pitch detection. Please email gc-dev-studios@protonmail.com with the file name and what you expected, and we will look at it.
