Orban is an American audio processing company founded by Bob Orban in 1967, with its first product sold to WOR-FM in New York City. The company is best known for its OPTIMOD line of broadcast audio processors, which became an industry standard for radio stations seeking a loud, clean, competitive on-air sound. The original Optimod 8000 was the first audio processor to combine FM processing and a stereo generator in a single package, and later models such as the Optimod 8100, 8200, 8400, 8500, and 8600 extended that legacy into the digital era.

The company's product line spans AM, FM, DAB+, HD Radio, TV, and streaming, with flagship units including the OPTIMOD 8700i for FM and digital radio, the OPTIMOD 5500i and 5750 for FM broadcasters, the XPN-AM/Optimod 9300 for AM, and the Optimod-PCn software processor for internet streaming and mastering. Orban also develops audio codecs and loudness-measurement tools used in production and transmission chains.

Headquartered in the United States with a European office in Ludwigsburg, Germany, Orban primarily serves professional broadcasters rather than musicians, and its clients include major networks such as iHeart, Audacy, Cumulus, WDR, and RTL. Over its history the company has been associated with Harman International, Circuit Research Labs, and Daysequerra.

Orban has 5 products cataloged on Equipboard, including Effects Processors. Their gear is featured by 5 artists, with the strongest followings in Rock, Pop, and Folk, World, & Country. Notable users include Ric Ocasek, James Petralli, and Dave Clauss.
