  • 2. What is MP3? MP3 is a near-CD quality file format for sound files, and is very popular for music on the web. It's becoming more popular as people use it to swap music online because of its powerful compression. For example, you can get hundreds of songs on a single CD using the 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. This means that for the first time it's become practical to make music available for download over the internet as download times have been drastically cut. MP3 strips out a lot of the information recorded in a song that our ears aren't able to hear and uses complicated math to reduce the file size.
