Dolby Laboratories is an American audio and imaging technology company founded by engineer Ray Dolby in London in 1965 and now headquartered in San Francisco. The company rose to prominence in the late 1960s and 1970s with its Dolby A, B, C, and S noise reduction systems, which became standard on professional tape machines, consumer cassette decks, and film soundtracks, and later with Dolby Surround, Dolby Digital, and Dolby SR for cinema.

In music production, Dolby licenses rather than manufactures most consumer gear, but its formats have shaped recording and playback workflows for decades. Dolby Atmos Music extends the company's object-based spatial audio platform to stereo-first genres, and is supported across DAW tooling, monitor controllers, and streaming services including Apple Music and Tidal. Dolby also operates mixing and mastering facilities and publishes reference specifications used by studios building Atmos-capable rooms.

The company's broader catalog spans Dolby Vision HDR imaging, Dolby Voice for conferencing, and Dolby.io developer APIs for streaming and communications. While Dolby branding is more commonly encountered on playback devices, receivers, and film prints than on instruments or outboard gear, its codecs and monitoring standards remain a fixture in professional recording, post-production, and broadcast environments.

Dolby has 12 products cataloged on Equipboard, including Effects Processors, Utility Plugins, and Power Amplifiers. Their gear is featured by 11 artists, with the strongest followings in Pop, Electronic, and Rock. Notable users include Glenn Rosenstein, Paul McCartney, and Caleb Followill.
