FMR Audio is an Austin, Texas-based pro audio manufacturer founded in 1997 by Mark McQuilken. The company built its reputation on affordable studio processors that pair analog signal paths with microprocessor-controlled sidechains, delivering professional performance at a fraction of the price of boutique outboard gear.

The company's best-known product is the RNC1773 Really Nice Compressor, a compact stereo unit that became a mix-room staple thanks to its clean, low-artifact compression and distinctive SuperNice multi-stage mode. FMR expanded the line with the RNLA7239 Really Nice Leveling Amplifier, which offers a warmer, more colored FET-style character, and the RNP8380 Really Nice Preamp, a two-channel mic pre in a 1/3-rack form factor with switched gain and high-impedance DI inputs. The company also produces 500-series versions of its core compressors (RNC500, RNLA500) and the PBC-6A, a parallel bus compressor.

FMR Audio's designs are frequently cited in home studio and project studio circles on forums such as Gearspace and in reviews from Sound on Sound and Tape Op, where the RNC in particular is often recommended as a transparent utility compressor for tracking vocals, drum buses, and mix bus duty.

FMR Audio has 10 products cataloged on Equipboard, including Effects Processors, Preamps, and Overdrive Effects Pedals. Their gear is featured by 16 artists, with the strongest followings in Electronic, Rock, and Pop. Notable users include Joel Nielsen, Bryce Barsten, and Steve Albini.
