Standard Audio is a Los Angeles-based manufacturer of professional audio equipment focused on building unconventional outboard tools for record makers. The company's catalog centers on a small lineup of analog processors, including the Level-Or Mk2 JFET limiter (offered as a 500 Series module and a dual-rack unit) and the Stretch multi-band compressor/equalizer 500 module.

The company has a reputation for taking inspiration from obscure vintage circuits and reinterpreting them as modern studio tools. The Level-Or, for instance, draws on the aggressive limiting and harmonic distortion character of the Shure Level-Loc PA limiter from the 1960s and '70s, while the Stretch is built around the multi-band dynamics behavior found in vintage tape noise-reduction encoders. The Level-Or has also been adapted into a software plugin developed in collaboration with Safari Pedals.

Standard Audio's products are sold through specialist pro-audio retailers such as Vintage King, Front End Audio, KMR Audio, and Funky Junk, and the gear is reviewed in publications like Tape Op. The brand is generally regarded within the professional recording community as a small, boutique outfit oriented toward engineers looking for character-driven analog dynamics processing.

Standard Audio has 3 products cataloged on Equipboard, including Effects Processors. Their gear is featured by 6 artists, with the strongest followings in Rock, Pop, and Folk, World, & Country. Notable users include Moses Schneider, Ryan Petersen, and Sabrina Carpenter.
