Though a WAV file can hold audio compressed with any codec, by far the most common format is PCM audio data. Since PCM uses an uncompressed, lossless storage method which keeps all the samples of an audio track, professional users or audio experts may use the WAV format for maximum audio quality. WAV audio can also be edited and manipulated with relative ease using software.
As file sharingFile sharing is the activity of making files available to other users for download over the Internet, but also over smaller networks. Usually file sharing follows the peer-to-peer (P2P) model, where the files are stored on and served by personal computers over the InternetThis article is about the Internet the extensive, worldwide computer network available to the public. An internet is a more general term for a set of interconnected computer networks that are connected by internetworking''. WWW information network structu has become popular, the WAV format has declined in popularity, primarily because uncompressed WAV files are quite large. More frequently, compressed but lossyA lossy data compression method is one where compressing a file and then decompressing it retrieves a file that may well be different to the original, but is "close enough" to be useful in some way. This type of compression is used a lot on the Internet a formats such as MP3MP3 (or, more precisely, MPEG-1/2 Audio Layer 3 is an audio compression algorithm capable of greatly reducing the amount of data required to reproduce audio, while sounding like a faithful reproduction of the original uncompressed audio to the listener., Ogg Vorbis and Advanced Audio CodingAdvanced Audio Coding AAC is a lossy data compression scheme intended for audio streams. AAC was designed to replace MP3. AAC, ISO/IEC 13818-7, is an extension of the MPEG-2 international standard, ISO/IEC 13818-3. It was further improved in MPEG-4, MPEG- are used to store and transfer audio, since their smaller file sizes allow for faster transfers over the Internet, and large collections of files consume only a conservative amount of disk space. There are also more efficient lossless codecs available, such as FLAC, TTA or Apple Lossless.
