Converter MPEG to MPC

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.

MPC is one of the files of the Audio category. This unlicensed file format is intended to store audio information. The MPC format (i.e. Musepack Compressed Audio File) was created by Musepack. Musepack is a lossy compression scheme developed by German programmer Andree Buschmann. He started creating the codec in 1997. At that time he had the name MP +. The developer was not satisfied with the existing quality of MP3 coding. The algorithm is based on MP2 (MPEG-1 Layer 2), where there are 32 frequency bands, but with significant improvements. Over the past years, it has undergone revision and has become much better. It is currently at a more advanced stage, which contains highly optimized and unpatented source code. The MPC encoding quality at high bitrates (160 Kbps and more) is much higher than the quality that MP3 provides. During coding, a different psychoacoustic compression algorithm is used. In MPC, frequencies that ignore MP3 encoders do not disappear. The specificity of MPC is the fine tuning of psychoacoustics. This provides the ability to operate with pure VBR encoding (variable bit rate encoding). The main task of Musepack is to obtain the highest transparency of sound.
