Zone:X is a game\visualizer which turns your voice into color and motion. I had to do some chinanegery to get the pitch detection working on this edition. It doesn't make sense how it works, but it seems to be about on point. Again, accuracy not guaranteed though it should work pretty well. If you are concerned about the accuracy you can compare it to the web edition which uses a correctly implemented YIN (from
Yin Yang)detection method. Bon appetit!
Zonex is not currently in mobile stores. You can still build from source if you want. Till it's back up here are the old links to the Stores anyways.
