Information about MP3 and AU file formats
| Name | 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 which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as 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 on 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 | The use of lossy compression is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio. An MP3 file that is created using the setting of 128 kbit/s will result in a file that is about 1/11 the size of the CD file created from the original audio source. | |
