The audio encoding formats WAV and MP3 mainly differ by the extent of compression and quality.The last layer among those layers is the MP3 layer which is the most complicated layer and designed to transmit audio over ISDN lines. The first layer provides high bitrate good quality while as we go to the downward layer, the quality and size both reduces. MPEG audio establishes three downward compatible layers of audio compression each capable of understanding the layer locating lower to them. MP3 creates a part of the audio component of the MPEG. Although, the MPEG standard actually defines three distinct characteristics of the multimedia such as audio, video and systems. The “3” in MP3 describes layer 3 and “MP” stands for the MPEG-1 standard. For example, an audio CD can contain one hour of uncompressed LPCM sound, when the same CD is recorded using MP3 compression, it can hold at most seven hours of the same music but with slightly degraded quality. The algorithm involved in this file format is the lossy type where a large amount of information is stored by consuming less amount of space. MP3 is also an audio file format developed by MPEG (Moving Picture Experts Group) in the year of 1990s and expanded as the most prevalently used technology for saving consumer audio.

Start.wav, chimes.wav, chord.wav, logoff.wav are the system event sounds involves in the windows system. In windows system, the sound files exist in the WAV format and reside in the windows\media subdirectory. All the sound editing programs support these uncompressed file formats. The WAV and AIFF (Audio Interchange File Format) files can be interchanged as these are rival container format and compatible with each other.
It can also be proved by the situation when a CD is inserted into a windows computer, the track icon will be presented by WAV files.
The CD’s and DVD’s were in WAV which means the audio quality stored in CD’s and DVD’s is of good quality. It is comprised of raw uncompressed PCM audio streams. It was devised by the joint effort of the Microsoft and IBM. WAV is the general container format for the digital audio known as Waveform Audio File Format (WAV or WAVE).
