Convert MPEG to OPUS

Converting one file format to another may be necessary for various reasons. So, for example, you may want to convert MPEG to OPUS 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).

The main advantages of OPUS are high audio quality and good compression achieved through dynamic adaptive streaming. The format is based on technologies and broadcast algorithms from Skype and Xiph.org (SILK and CELT codecs, respectively). OPUS is the main audio codec in Skype today. Opus' structure allows it to effectively deal with sound artifacts. For this, a multi-stage audio signal processing architecture has been proposed. The main argument that speaks in favor of using the new codec for IP telephony is low time delay. The Opus codec is used for Voice over IP (VoIP), video conferencing, in-game chat. The Opus format has been standardized by the IETF and is maintained by Xiph.Org. Audio file encoded using the Ogg Opus lossy encoding format. The Opus format is designed for Internet audio streaming, that is, the transmission of sound over the Internet. The main advantages of the codec are low encoding latency (from 2.5 to 60 ms) and its high speed, a very high compression ratio of audio data with a very decent sound quality, support for multichannel audio (up to 255 channels). Opus is a completely open source, royalty-free, highly versatile audio codec. Opus is good for streaming both speech and music over the Internet. It's also great for storage and streaming.
