Shattered Glass Audio is an independent audio software company based in Los Angeles, California, founded in 2009 by engineer and producer David Glass. The company develops digital plugins and analog-inspired processors for music production, with a focus on emulating vintage tube circuits, classic console preamps, and guitar amplifiers.

The company is widely known for its lineup of free plugins, including the SGA1566 tube preamp/saturation processor modeled on a single-channel vintage tube preamplifier, Ace, an emulation of a 1950s American tweed 5-watt all-tube combo amp, and Code Red Free, a console emulation inspired by a late-1960s British tube mixing console. Paid releases include the Mini Cracked Glass distortion plugin, the Inferno amp/distortion plugin, and the Phoenix LT tube preamp, which is offered for desktop DAWs as well as iOS.

The plugins are distributed in VST, VST3, AU, and AAX formats and have built a following among home producers and engineers looking for affordable analog-style coloration tools. The company's tube and console modeling is regularly cited in plugin community reviews on sites like KVR Audio, Gearspace, and Bedroom Producers Blog.

Shattered Glass Audio has 3 products cataloged on Equipboard, including EQ Plugins, Amp Simulator Plugins, and Channel Strip Plugins.
