What is AAC known for in relation to audio compression?

AAC, or Advanced Audio Codec, is widely recognized as a successor to MP3, which is a significant development in audio compression technology. It was designed to provide better sound quality at similar bit rates compared to MP3. This means that audio files encoded in AAC can deliver higher fidelity, allowing for better overall listening experiences, especially in streaming scenarios where bandwidth is limited.

The transition from MP3 to AAC also includes support for more channels, improved compression techniques, and better handling of sound frequencies, particularly in higher quality audio. This advancement makes AAC a popular choice for modern audio applications, including digital broadcasting and streaming services.
