Converter MPEG to QCP

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.

QCP is an audio file category format. It has the full name Qualcomm PureVoice Audio File, since the format was developed by Qualcomm. The main application is the preservation of various types of recorded sound. The development of this format was in the company specifically for recording, storage and playback of all frequencies of the human voice. Files with the .QCP extension are most often used specifically for recording human voices, as well as for processing pauses that are natural for human speech. QCP files are also widely used for recording ringtones for mobile phones. They are very often applied as a sound attachment to emails. The standard plugin for many email programs is the PureVoice Player-Recorder program, which allows you to listen to the email application as a file with the .QCP extension. Also on any device, you can install the PureVoice SDK plugin, which allows you to listen to sound files with the extension .QCP. QCP belongs to the category of container formats. He can not independently set the encoding parameters of sound files. Inside the file with the extension .QCP there are files that use the EVRC or QCELP method for encoding.
