Convert MPEG to MP3

Converting one file format to another may be necessary for various reasons. So, for example, you may want to convert MPEG to MP3 if your computer, phone or other device does not support MPEG format. Also, conversion is often required to reduce the file size, since the original format takes up too much space in the device's memory. Perhaps you just need to extract the audio track from the video file, in which case converting the video to audio format is a good option. In any case, with the help of our converter, you can easily complete the required task. Below you can find out some details about the original and new file formats.

In January 1988, an expert working group on coding of moving images was formed within the framework of the joint information technology technical committee JTC1 of the International Organization for Standardization ISO and the International Electrotechnical Commission IEC, which was tasked with developing standards for image and sound coding with the aim of eliminating redundancy. MPEG compression standards were developed by Moving Picture Experts Group. This technology defines the compression standards for both audio and video information and makes it convenient for transmission in broadcast. There are many versions of the format - MPEG-1, MPEG-2, MPEG-3, MPEG-4, etc. MPEG-1 is a lossy compression standard for video and audio. It is designed to compress VHS. Perhaps everyone is familiar with the MPEG-2 format. It is this format that underlies DVD-Video discs. The MPEG-2 format is also the basis for digital television standards. The MPEG3 standard was originally developed for use in High Definition Television (HDTV) systems with a data rate of 20-40 Mbps. The new MPEG4 standard, which appeared at the very end of 1999, offers a broader view of media reality. The standard defines the principles for working with content (digital representation of media data) for three areas: interactive multimedia itself (including products distributed on optical discs and over the Internet), graphics applications (synthetic content) and digital television (DTV).

MP3 (formally MPEG-1 Audio Layer III or MPEG-2 Audio Layer III) is an encoding format for digital audio developed primarily by the Fraunhofer Society in Germany with support from other digital scientists in the United States and other countries. Today, most of the audio recordings that a person listens to almost every day are presented in the form of universal MP3 files, since they are the most common and demanded in terms of the format for storing audio information. MP3 format is a streaming format. This means that data transmission occurs as a stream of independent separate data blocks - frames. For this, the original signal during encoding is divided into sections of equal duration, called frames and encoded separately. When decoding, the signal is formed from a sequence of decoded frames. Unlike conventional archivers, which need to manage to compress information in such a way that not a single bit is changed in it after extraction from the archive, MP3 serves somewhat different purposes. In addition to mathematical compression algorithms, this format also contains the most complex algorithm for removing unnecessary audio information, based on the psychological and physiological characteristics of the human body.
