Information about MP3 and SPH file formats

Name MP3 SPH
Full name MP3 - MPEG-1 or MPEG-2 Audio Layer III NIST SPHERE Audio File
File extension .mp3 .sph
MIME type audio/mpeg, audio/MPA, audio/mpa-robust
Developed by Fraunhofer Institute Institute of Standards and Technology (NIST)
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. Waveform audio file created in the NIST SPHERE format, which is often used in speech recognition research; often contains a recording of a person speaking; can be provided as input to speech recognition systems.
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.
