What is an AVR file?
An AVR file is an audio file saved in the Audio Visual Research (AVR) format, a proprietary format developed for older Atari ST computer systems. It stores audio data in 8- or 16-bit formats and supports either 1 or 2 audio channels. Since Atari ST computer systems are no longer common, AVR files are now obscure.
More Information
Audio professionals and enthusiasts who worked with Atari ST computers were the most likely to encounter AVR files. Due to its specific hardware dependencies and advances in audio technology, the AVR file format has become largely obsolete and is seldom used today.
