ASR was founded in February 2016 by Amir Majidimehr (known as amirm on ASR[1]), who resides in the area of Seattle, Washington in the USA. He was previously Vice President of Microsoft's Digital Media Division until retiring in 2008. He is an electrical engineer by degree and hobby, with professional experience including software and signal processing.[2]

As of November 2020, ASR has approximately 1.1 million visitors per month,[3] 13,000 threads, 543,000 messages and 16,000 members.[4] The website is funded solely by its founder and member donations.

ASR initially focused on performance tests of desktop audio equipment such as digital-to-analog converters (DACs) and headphone amplifiers. Testing has since expanded into many other kinds of home audio and professional audio equipment, provided largely by forum members and some manufacturer submissions.[5] Testing uses industry standard electronic test and analysis equipment.

Audio equipment testing using measurements-based methods is contentious. ASR advocates for audio equipment evaluations based on established peer-reviewed studies in electronics, signal processing, acoustics and psychoacoustics.

In 2020, ASR became notable for independently publishing comprehensive loudspeaker performance measurements according to the CEA 2034 standard.[6]
