Converter OPUS to MP4

OPUS is an audio file that is encoded using the Ogg Opus format (lossy coding). It was created for online audio streaming, that is, in order to transmit sound through a global network. The format is being developed by the Internet Engineering Task Force (IETF) and Xiph.Org communities. Applies SILK codecs when used in Skype and CELT (from Xiph.Org), provides support for variable bitrate. Most often, the OPUS codec is used for video conferencing, game chats, VoIP telephony. OPUS is a free audio codec that has international standard status (IETF RFC 6716). Its main advantages are a low coding delay (from 2.5 to 60 ms) and its significant speed, an increased degree of compression of audio data with high-quality sound, as well as support for multi-channel audio (within 255 channels). In 2011, J. Skeglund of Google conducted two series of tests, during which OPUS coding and decoding were compared, taking into account the assessments of experts and ordinary listeners. Studies have shown that OPUS provides stereo music with the same quality as MP3 and better quality than G.719 64 kbps. OPUS offers great streaming capabilities with dynamic tweaking and very low latency. This is always high sound quality and excellent data compression. Full support for OPUS is provided by Mozilla applications. He is the key Skype audio codec.

MP4 is an abbreviation for MPEG-4 Part 14. It can also be called MPEG-4 AVC. In this case, the abbreviation AVC (Advanced Video Coding) is an advanced video encoding. By the name of the format, it is easy to guess that it is necessary for working with video files. The format was first proposed in 1998. Since then, MP4 is considered one of the most common file formats used to store and transmit multimedia. MP4 is a container format that provides the ability to combine audio, video, subtitles and pictures in one file. It is also suitable for posting rich content. Say three-dimensional graphics, menus and interactive features. There are many portable players and other devices that play MP4. For this, a PC or laptop is also quite suitable. The MP4 format is a robust application that needs relatively low performance. And therefore, users could use such a tool for their own purposes. This tool has found wide application, as the technology for the production of more and more powerful devices, both portable and desktop with a large hard drive capacity, is constantly evolving. Due to the fact that the speeds of various types of connections to the global network are increasing, MP4 has become more affordable. It acts like the MP3 format, although it is more complex. The format compresses files and remains high-quality.
