The best place to play surround 5.1 sound is in movie theaters. Using AAC format, people can feel the sound quality without significantly reducing the premise, which is also more compact. Unlike MP3, it uses a new algorithm for encoding, which is more efficient and cost-effective.
It is a file compression format specially designed for sound data. It’s clear that AAC file sounds much better than MP3 at the same bit rate, and until now, no MP3 file can surpass the AAC file at 256 Kbs. In 2000, after the emergence of the MPEG-4 video standard, AAC reintegrated its features, adding SBR technology and PS technology, in order to distinguish itself from the traditional MPEG-2 AAC, also known as the MPEG-4 AAC.ĪAC is designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 for a given data rate (e.g., 128 kbps) and at the same bit rate, and is playable in almost all software that can play MP3 files. Developed by Fraunhofer IIS, Dolby Labs, AT&T, Sony and other companies, the aim is to replace the MP3 format.
AAC appeared in 1997 and based on MPEG-2 audio coding technology.
