Townsend Labs is a professional audio company founded by Chris Townsend and Erik Papp, known for pioneering multi-dimensional microphone modeling technology. Chris Townsend was previously Guitar Products Architect at Avid Technology (where he helped develop the Eleven Rack), while Erik Papp served as CEO of Summit Audio for over a decade. The company's patented Sphere technology captures the full three-dimensional sound field of a source so that polar pattern, proximity effect, and off-axis response can be adjusted after tracking.

Their flagship product, the Sphere L22, is a dual-capsule large-diaphragm condenser microphone paired with DSP software that emulates a catalog of legendary condenser, ribbon, and dynamic microphones from makers such as Neumann, AKG, Telefunken, and Sony. The system runs natively as VST, AU, AAX, and on UAD/Apollo platforms, and has been used for tracking vocals, drums, guitars, and orchestral sources. A collaboration with Universal Audio produced the Ocean Way and Bill Putnam Mic Collections for Sphere.

In 2021, Universal Audio acquired the assets of Townsend Labs, with the founders joining UA to continue developing microphone products. The Sphere line, along with successor modeling mics, is distributed under the Universal Audio brand.

Townsend Labs has 1 product cataloged on Equipboard, including Condenser Microphones. Their gear is featured by 2 artists, with the strongest followings in Rock, Pop, and Folk, World, & Country. Notable users include Bora Karaca and Teddy Swims.
