I would like to share with you what audio format aac refers to. I hope you will get something after reading this article. Let's discuss it together.

Aac is a lossy compression audio format, Chinese name is "advanced audio coding", it uses a new algorithm for coding, more efficient, with a higher "performance-to-price ratio"; the use of AAC format, can make people feel that the sound quality is not significantly reduced on the premise of more compact.

AAC (Advanced Audio Coding), Chinese name: advanced audio coding. Appeared in 1997, based on MPEG-2 audio coding technology. It was jointly developed by Fraunhofer IIS, Dolby Labs, AT&T, Sony and other companies to replace the MP3 format.

AAC is a file compression format designed for sound data. Different from MP3, it uses a new algorithm for coding, which is more efficient and has a higher "performance-to-price ratio". The use of AAC format, can make people feel that the sound quality is not significantly reduced under the premise of more compact. Apple ipod and Nokia phones support audio files in AAC format.

Advantages: the sound quality is better and the file size is smaller than mp3,AAC format.

Deficiency: AAC is a lossy compression format, and there is an "essential" gap in sound quality compared with popular lossless formats such as APE and FLAC. In addition, the faster transmission speed of USB3.0 and more than 16G high-capacity MP3 is accelerating the popularity, so that the "compact" halo on the AAC no longer exists.

Characteristics

Improved compression ratio of ①: higher sound quality with smaller file size

② supports multi-channel: up to 48 full-range channels

Higher resolution of ③: highest sampling frequency for 96KHz

Improved decoding efficiency of ④: decoding and playback takes up less resources
