AAC VS MP3: What are they?

MP3: What is it?

MP3 is an audio coding format developed in Germany. The Fraunhofer Society played a big part in its development. Karlheinz Brandenburg led the development team with other digital scientists. The file was adopted by MPEG (Moving Pictures Experts Group) as MPEG-1 and then MPEG-2. The format's lossy compression allowed for less storage consumption. MP3's capability to have good quality with less storage made it popular.

AAC: What is it?

AAC was proposed by Nasir Ahmed, who later developed it with T. Natarajan and K. R. Rao. Many major companies supported the format's development. AAC was created three years after MP3 to act as its successor. The file format still maintained the lossy compression but with better quality. AAC uses MDCT (Modified Discrete Cosine Transform), increasing compression efficiency. AAC is still smaller than MP3, but major tech companies like Apple are starting to embrace it.
