A 3G2 file is a multimedia file saved in an audio and video format developed by the 3rd Generation Partnership Project 2 (3GPP2). 3G2 files are designed for transmitting multimedia content over the Internet and are used by cell phones to save video files.
An OPUS file is an audio file created in the Opus format (also called "Ogg Opus"), a lossy audio format developed for Internet streaming. It uses both SILK (used by Skype) and CELT (from Xiph.Org) codecs and supports variable bit rates from 6 kb/s to 510 kb/s.
