About Advanced Audio Coding
AAC (Advanced Audio Coding) is a standardized, lossy compression and encoding scheme for digital audio.
Particularly, if bitrate is 100 kbit/s or less, AAC achieves better quality sound, than the more popular MP3 format due to the following features: - more sample frequencies (8 kHz - 96 kHz); - up to 48 channels; - arbitrary bitrates and changing frame length; - better efficiency and simpler filterbank; - higher coding efficiency for stationary and transient signals; - better handling of frequencies above 16 kHz; - more flexible joint stereo; - additional modules for increasing compression efficiency. AAC is the default format for compressing audio CDs for Apple's iPod and iTunes. AAC is also used as the standard audio file for Sony's Playstation 3 and as the default audio codec for the .m4v format which Apple employs in the iTunes Store video files. |
