description Disclosed are various embodiments for a system and method for encoding sub-audible codes within a signal. One exemplary embodiment includes a method that includes receiving a first digital code and a second digital code; receiving a first block and a second block of a signal; embedding an echo of the first block of the signal in the second block of the signal to create a first modified second block of the signal in accordance with the first digital code; modulating the power of the first modified second block of the signal to create a second modified second block of the signal in accordance with the second digital code; and sending a modified signal including the second modified second block of the signal.
