The AVR (Audio Visual Research) file format is a proprietary audio format developed by Audio Visual Research for use on Macintosh computers. It was primarily used in older Mac operating systems and is less common today. AVR files were designed for storing digitized audio data, often used in conjunction with early audio editing and processing software on the Mac platform. This format allowed for the storage and manipulation of various types of audio information, making it a useful tool for researchers, musicians, and audio engineers during its time of popularity.
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.
