As we learned earlier, in order to be sent over computer networks, information must be in a digital format. There are many software programs available to convert analog audio to digital. The problem with delivering these files over networks is that they are so big. Not only would they take up large amounts of disk space to store, but they take a very long time to receive over networks. These files are very large, but the sound quality can be high.
File sizes are large, but quality is high.
Because it delivers CD-quality sound, MP3 is favored by music fans. Intellectual property issues have made MP3 on the Web a hot issue. There are large archives of midi music on the Web. This is called streaming . Files are also compressed, so they take up less room to store.
