Information about MP3 and AU file formats
|🔸 File format||MP3||AU|
|🔸 Full name||MP3 - MPEG-1 or MPEG-2 Audio Layer III||Sun Microsystems AU files|
|🔸 File extension||.mp3||.au|
|🔸 MIME type||audio/mpeg, audio/MPA, audio/mpa-robust||audio/basic|
|🔸 Developed by||Fraunhofer Institute||Sun Microsystems|
|🔸 Type of format||Digital audio|
|🔸 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.||The AU file format is a simple audio file format introduced by Sun Microsystems. AU format was common on NeXT systems and early Web pages. Originally it was headerless, being simply 8-bit μ-law-encoded data at an 8000 Hz sample rate. Hardware from other vendors often used sample rates as high as 8192 Hz. Newer AU files have a header that consists of six unsigned 32-bit words.|
|🔸 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.|
