Converter MPEG to WAV

MPEG is a special standard for compressing audio files and video files into a different format, which is most convenient for downloading or forwarding, say, over a global network. The specified standard was developed by the Moving Picture Experts Group. It was created by the international organization ISO just in order to develop a standard for the compression and transmission of digital video and audio data. The official designation for this group is ISO / IEC JTC1 / SC29 WG11. The first time she met in Ottawa in May 1988. By 2005, up to 350 people became participants in the meetings. MPEG, that is, Moving Picture Experts Group, consists of 3 components: Audio, Video, System (combining and synchronizing the other two). There are different MPEG standards, which are also called phases: MPEG-1, MPEG-2, MPEG-3, MPEG-4, MPEG-7. According to the MPEG-1 standard, for example, streams of video and audio data are sent at a speed of 150 kilobytes per second. The speed of a single-speed CD-ROM player is similar. Streams are managed by sampling key video frames and filling in areas that change between frames. This standard ensures the quality of the video image is significantly lower compared to the video that is transmitted on the television standard.

WAV (or WAVE) is actually the first full-fledged audio format with good sound quality. It was developed quite a few years ago by the joint efforts of Microsoft and IBM. Sometimes this format is even called “Audio for Windows,” because it is the standard for storing audio stream for a traditional Windows desktop computer. Full name - Wave Audio File Format. The short name is derived from the English word wave ("wave"). The peculiarity of this format of digitized audio stream is the lack of compression. WAV files take up too much space, but it is ideal for storing high quality files in their original form.
