File extension.mp3 Category Description MP3 is a digital music format which allows CD tracks to be reduced to around a tenth of their normal size without a significant loss of quality. MP3 gets rid of a lot of the information recorded in a song that our ears are not able to hear and then uses complex algorithms to reduce the file size. This then enables you to get hundreds of songs on to a CD and it also has opened up a new market over the internet - the download market as download times have been significantly reduced. Actions Technical Details The MP3 format is a lossy format.
That means that an MP3 file does not contain 100% of the original audio information. Instead, MP3 files use perceptual coding.
