I’m creating a sound installation and I’m a novice Processing programmer. There will be 2 audio files. I’d like to scramble the 2 files to create a mashup of the 2 sounds, then I’d like to reverse the process and unscramble the sound files. I know how to scramble the files but not sure how to keep track of the mashup to unscramble them. Any help would be greatly appreciated.

Please elaborate on what scramble is in the context of your project.

I was making breakfast and scrambling 2 eggs this morning and thought about how to unscramble them and get the eggs back.

The 2 audio files would be equal length. Then for example, I will randomly take segments from one audio file and swap them with equal segment the other file. So each file would have segments from the other file.

I thing that I need to create an array that contains, [frame, length], so I could scan the array and put the original segments back together in their proper place.
