This document proposes enhancing audio cryptography through an enhanced genetic algorithm. The algorithm genetically engineers each audio sample to produce new samples. It encrypts audio by acquiring, conditioning, and transforming each sample into bit strings, then applying bit-level operations like fission, switching, mutation, and fusion to generate encrypted audio signals. The original audio is recovered losslessly through decryption. This technique integrates fission and fusion into a genetic algorithm, using a single individual for reproduction rather than two. It is presented as an improvement over existing audio security methods for embedded systems.
