Unable to convert music to 528hz

I’m unable to convert mp3 files over 500 hz. Everyone to try to manually enter 528 hz, the app sets me back to 400 hz.

Revolutionary app, a new understanding hz frequencies

I suspect the two star rating was from someone that didn’t understand this app or know how to use it because this App is priceless with sound healing. I was able to convert my music from 440 to 432 hz and so on with 528 hz. Among numerous other healing frequencies. At first I was thrown off because I was trying to change my 440(base hz) music to 528(projected hz) and it kept defaulting to “444”, I had no clue what that meant at the time. So I messaged the developer and later found out that the hz converter is always to the standard A. For instance, 528 Hz corresponds to an A of 444 Hz. I looked it up on handy google and this was correct. So 444 would translate to creating a 528 hz. Thank you for the frequency fact and designing an awesome tool that will help millions. When I make music and change the hz, it automatically saves to specific hz folder file on my phone(separate from everything else and easy to find) make it easy to stay organized. :)

Awesome app!

Absolutely love how easy it is to convert music to a new frequency! I have one question though: what is the difference between algorithm-based and spatial-based? I’ve been trying to look it up but I can’t find an answer.

Developer Response ,

Thanks for your feedback. The two algorithms yield different results. Depending on the input music, sometimes one, then the other algorithm works better.
