Two methods of reversible audio encryption in Max

This project demonstrates 2 reversible methods of encrypting audio

  • reciprocal (1/x)
  • frequency shifting

The reciprocal method is interesting because the reciprocal of a reciprocal is the original value. In other words you can reverse the process by doing it twice.

Frequency shifting allows you to ‘hide’ audio in the ultrasound range.
