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.


Free Lossless Audio Codec (FLAC)

FLAC is an open-source lossless format created as part of the Ogg project. In recent years, it has become the go-to choice for listeners who want to preserve the original quality of their music. One of the advantages of FLAC is that it supports IDv1 and IDv3 tags, making it easy for users to organize their collections by editing track metadata without altering the actual sound.
