The rapid advancement of technology is closely linked to the development of the modern era. Technology is always expected to provide convenience to each user according to their individual needs, especially when it comes to sending messages. In the present day, sending messages is a fundamental necessity and security plays a crucial role. Data transmission can be easily intercepted by third parties, even if the data are private or confidential. Therefore, it is crucial to have a security approach in place. However, some methods introduced earlier have not been suitable in terms of the capacity and quality produced. This study addresses this issue by using audio as a medium to insert a secret message. This research focuses on optimizing the quality of the stego-audio produced without reducing the insertion capacity. The experimental results show an increase in quality based on the Peak Signal-to-Noise Ratio (PSNR) evaluation results. © 2024 Praise Worthy Prize S.r.l.-All rights reserved.
