What will become of pur world without music? I don't even want to think about that. Music is all around us like in the movies, in the cars, even at elevators! And maybe because of it popularity people have found many many ways to record music. That is why there are so many types of files for it. And the best thing is that you can find the all in Webopedia.
Mp3
This one is the most popular. It is used by eliminating background noises.
It is named Mp3 because it works with three layers. It compresses audio into the third.
WMA
This one is only used in Windows therefore it is not as popular obviously. It has smaller size and lower quality than WAV.
WAV
It is short for WAVE form. Audio file format is a digital audio format without data compression normally developed and owned by Microsoft and IBM that is used to store sounds on the PC, supports both mono and stereo files to various resolutions and sampling
AIFF
It is short for Audio Interchange File Format, which is a common format for storing and transmitting sampled sound. It was developed by Apple therefore is mostly used in macintosh. It does not compress data for it you can have AIFF- compressed another format.
RA
The de facto standard for streaming audio data over the World Wide Web. RealAudio was developed by RealNetworks and supports FM-stereo-quality sound. To hear a Web page that includes a RealAudio sound file, you need a RealAudio player orplug-in, a program that is freely available from a number of places. It's included in current versions of both Netscape Navigator andMicrosoft Internet Explorer.
