Advanced Audio Coding (AAC)

AAC was introduced as a successor to the MP3 format with the goal of delivering better audio quality while keeping file sizes small. Early attempts weren’t very impressive, but over time the technology matured. Today, AAC can compress audio efficiently, providing clearer sound with file sizes similar to MP3, but usually with less noticeable loss in quality.

Compressed Audio File (M4A)

M4A is a lossless audio format commonly associated with Apple platforms. It became popular thanks to its use in iPods and as part of the QuickTime player. Since its decoding technology is available through open-source libraries, many third-party applications can play M4A files without restrictions.
