Information about MP3 and AAC file formats
|Full name||MP3 - MPEG-1 or MPEG-2 Audio Layer III||AAC - Advanced Audio Coding|
|MIME type||audio/mpeg, audio/MPA, audio/mpa-robust||audio/aac|
|Developed by||Fraunhofer Institute||Bell Labs, Fraunhofer Institute etc.|
|Type of format||Digital audio||Audio compression format|
|Description||MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio that uses lossy data compression. It is a common audio format for consumer audio streaming or storage and a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players.||Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. ISO and IEC have standardized AAC as part of the MPEG-2 and MPEG-4 specifications.|
|Technical details||Lossy compression is designed to reduce significantly the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio. For example, an MP3 file created using the setting of 128 kbit/s will result in a file about 1/11 the size of the CD file created from the original audio source.||AAC supports the inclusion of 48 full-bandwidth audio channels in one stream plus 16 low-frequency effects channels, up to 16 "coupling" or dialog channels, and up to 16 data streams. The quality for stereo is satisfactory to modest requirements at 96 kbit/s in joint stereo mode; however, hi-fi transparency demands data rates of at least 128 kbit/s.|
