Abstract
This paper analyzes the application of efficient audio compression algorithms on mobile devices and proposes an optimization scheme for Advanced Audio Coding (AAC) method. Firstly, explore the basic principles of the AAC method. Secondly, the Modified Discrete Cosine Transform (MDCT) is introduced to optimize the AAC method, achieving efficient compression and encoding of audio signals by improving the accuracy and compression performance of frequency domain analysis. Finally, develop relevant software in Android Studio and conduct experimental testing using an Android emulator.
