AAC

AAC (Advanced Audio Coding) is a lossy audio compression format standardized by ISO/IEC and designed as a higher-quality successor to MP3. It achieves better audio fidelity than MP3 at the same bit rate by using more advanced psychoacoustic models and encoding techniques. AAC is the default audio format for iTunes, Apple Music, YouTube, and all iOS devices, and is supported natively across virtually every modern platform.
