MP3 format

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 have a much smaller file without losing any quality or having to download extra software. You will often see MP3 files with the .mp3 extension.
