WAV (WAVE) files are audio files playable via multimedia playback software such as Windows Media Player and other software available for your operating system. These files contain any sounds such as sound effects, music or spoken words. WAV files are large in size and with the advent of MP3 and MP4 WAV files are becoming less popular and less common. They were created and developed by IBM and Microsoft but unlike MP3 and MP4 the WAV file format does not use a form of lossy compression so file sizes are therefore much bigger and now less popular.
WAV format is intended for operation with digitalized audio stream. It contains musical compositions, voice recordings, and various audio effects. Developed by programmers from Microsoft and IBM, it is a key format for placing of uncompressed sound files on Windows PCs. The files can be played back in QuickTime, Windows Media Player, Wav Player and some other programs. In addition to that, they can be processed in audio editing apps.
When a file is compressed into WAV, the data are not supposed to be lost, and the quality is excellent. However, the format did not have a huge market share, due to its larger size, as compared with MP3. It is required to have enough time and disc space to upload and send such files via the Internet. One of the major advantages of WAV is linked to the use of Linear Pulse Code Modulation (LPCM) for storage of audio stream. Consequently, a copy is just as good as an original, which is highly appraised by experts in music and professional users.
Wav files are the standard digital audio format in Windows. Using the .WAV file extension, 8- or 16-bit samples can be taken at rates of 11,025 Hz, 22,050 Hz and 44,100 Hz. The highest quality being th 16-bit at 44,100 HZ, this highest level is the sampling rate of an audio CD and uses 88KB of storage per second. All general sounds in Windows, such as when you log in, are in the .WAV format. The default content of a WAV file is uncompressed (although they can be used to store compressed formats such as MP3), pulse code modulated (PCM) digital samples derived from the analog source.
Sound files with this extension are recorded into 8 or 16 bit per sample. A standard option for CD Audio is an audio stream of 16 bit per sample and sampling frequency of 44.1 KHz. One second of sound corresponds to 88 Kb of internal memory. WAV files can store metadata in the INFO chunk, and they also include integrated IFF lists.
In some cases, the standard format may be used for broadcasting. For instance, BBC stereo data of 44 100 Hz and 16 bit are generally accepted within the VCS system.

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. MP3 gets rid of a lot of the information recorded in a song that our ears are not able to hear and then uses complex algorithms to reduce the file size. This then enables you to get hundreds of songs on to a CD and it also has opened up a new market over the internet - the download market as download times have been significantly reduced.
MP3 is a digital format for storage of audio files designed by MPEG programmers. It is one of the most required codecs for digital coding. The format is widely used in various file-sharing sites for evaluation downloading.
With this format, it is possible to compress CD tracks up to 1/10 of their original size while maintaining high playback quality. Overtones, which cannot be perceived by a human ear, are removed. Complex algorithms allow for smaller size of tracks. As a result, one compact disk can contain several hundred songs. MP3 is compatible with all most popular operating systems and supported by the most of modern DVD-players and music systems.
The MP3 format is a lossy format. That means that an MP3 file does not contain 100% of the original audio information. Instead, MP3 files use perceptual coding. In other words, that means it removes the information that your ear doesn't notice thereby making the file smaller. The reason lossy formats are used over RAW is that RAW audio files are too large to travel over the internet at any great speed. By using lossy formats it enables even dial up users to download mp3 files at a reasonable speed. RAW file formats generally require 176,000 bytes per second compared to a lossy format which requires 17,600. The difference is massive and so are the download times.
Prior to MP3 introduction, MPEG-1 had been widely used. That format contained not only audio data, but images as well. MP3 breaks an audio file into parts of the same length. When the processing is over, each part is packed into its own frame. It involves the technology of spectral limit that requires a continuous input signal to provide the use of two adjacent frames.
When spectral deleting is over, the file is to be compressed with mathematic methods. If necessary, compression rate can be changed, even inside the same frame. Files of 128 kbit/s have 11-fold compression. Further reduction of the file size will lead to significant deterioration in sound quality.
