The importance of audio data in different areas such as telecommunications, entertainment, and confidential information shows the need for advanced encryption methods. In the ever-evolving information security environment, the need for strong and innovative encryption technologies is critical. Traditional encryption methods have long been the cornerstone of digital data security. However, as technology advances, so do the challenges of sophisticated attackers. The combination of chaos and DNA encoding not only hardens audio data against potential breaches but also ushers in a new dimension of secure communication. This study applies chaos theory and DNA encoding to audio encryption to demonstrate the importance of protecting audio data. In an era of growing concerns about privacy and data integrity, this innovative approach is a powerful solution for protecting audio information. Using chaos theory, it is possible to incorporate deterministic yet unpredictable dynamics to embed audio information in a chaotic system, which would be difficult to decode by traditional methods. To improve this strategy, DNA encoding is introduced to convert audio data into genetic code, using the information density and flexibility of DNA. Converting audio data to DNA code adds a layer of security and data density. The robustness of genetic material and the complex dance of chaos create a powerful encryption strategy that resists traditional cryptographic attacks.
