IGS Audio is a Polish manufacturer of professional analog studio equipment, based in Katowice and founded by producer and engineer Igor Sobczyk. The IGS Studio project has been operating since 1997, with the IGS Audio brand itself established in 2003 to build hardware informed by the needs of a working recording facility.

The company designs and hand-assembles outboard processors across several categories: compressors, preamplifiers, equalizers, reverbs, and 500 Series modules. Among its better-known units are the V8, a discrete diode-bridge compressor built around Carnhill transformers; the Zen, a compressor using hand-matched Zener diodes as the gain-reduction element; and the One LA 500, a high-voltage tube opto-compressor for the 500 Series format. IGS also produces outboard plate-style reverbs such as the Tubecore and T4B photocell units.

The gear is distributed through specialist pro-audio retailers internationally, including Vintage King, Funky Junk, Retro Gear Shop, and Front End Audio, and has a following in tracking, mixing, and mastering rooms that favor colored, transformer-based analog signal paths.

IGS Audio has 17 products cataloged on Equipboard, including Effects Processors and Preamps. Their gear is featured by 3 artists, with the strongest followings in Rock, Metal, and Electronic. Notable users include Kevin Parker, Glenn Fricker, and Lonas. Most IGS Audio products sit firmly in the high-end, boutique range.
