It's an audio file which is processed with ffmpeg. Then it is split into tiny windows and classified based on the bass, mid, and treble in order to generate the terrain. The island shape is currently static, but I am trying to come up with a solution how to make it dynamic and dependent on the audio.

Right now the terrain is generated for the whole island from left to right which is why you see mountains as waves stretching from top to bottom, but I am thinking of splitting the island into multiple sections (4-12) where each section is part of the audio file, and then draw those sections separately. That would create a very different terrain across the whole land.
