Why are there different types of files such as flac, mp3, mp3 64k, ogg, etc…?
Because we want to please any kind of needs. So, flac is a free lossless audio codec similar to wav. Flac files are in full CD quality. There are three kinds of mp3s: Better VBR (variable bitrate) mp3s with the minimum on 192 k bitrate, normal VBR mp3s, and low end 64k mp3s for low bandwidth downloads. The third format is ogg format. It’s a free format similar to mp3.
