|Full name||MP3 - MPEG-1 or MPEG-2 Audio Layer III||Speex|
|MIME type||audio/mpeg, audio/MPA, audio/mpa-robust||audio/x-speex, audio/speex|
|Developed by||Fraunhofer Institute||Xiph.Org|
|Type of format||Digital audio||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.||An SPX file is a Speex audio file saved within an Ogg Vorbis container. Speex is an open source patent-free audio format designed for speech compression. It supports variable bitrate (VBR) encoding and several features not found in other audio codecs. Some examples include embedded encoding, intensity stereo encoding, and voice activity detection.|
|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.|
