Audio Frequency Converter for Android

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.

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. :)
