Sterling Audio is a microphone and studio equipment brand based in Thousand Oaks, California, distributed exclusively through Guitar Center, Musician's Friend, and affiliated retailers. The line was developed in part by Aspen Pittman of Groove Tubes, and some models share design DNA with GT products. Manufacturing is based in China, and the catalog spans large-diaphragm condensers, small-diaphragm condensers, ribbon microphones, dynamic mics, and performance vocal mics.

The brand is known for offering studio-style microphones at accessible price points, with a number of large-diaphragm condenser models using a resonator disk mounted to the capsule to flatten and extend the high-frequency response. Notable products include the ST155 and ST169 condensers, the ST170 active ribbon, and the P10, P20, and P30 performance series vocal and instrument microphones.

Beyond microphones, Sterling Audio produces the Harmony H224 USB audio interface, SHA4 and SHA8 rackmount headphone amplifiers, and the S302, S402, and S452 studio headphones, positioning itself as a one-stop source for project and home studio recording gear.

Sterling Audio has 26 products cataloged on Equipboard, including Condenser Microphones, Windscreens & Pop Filters, and Active & Passive Monitors. Their gear is featured by 15 artists, with the strongest followings in Electronic, Rock, and Hip Hop. Notable users include Deorro, Josh Farro, and Jake Pitts. Sterling Audio's catalog spans the full price spectrum — from entry-level options to high-end flagships.
