What SILICON AUDIO does

Silicon Audio Seismic (operating as Silicon Audio) is an Austin, Texas-based private company founded in 2007 that designs and manufactures interferometer-based optical seismometers. The company's core technology combines traditional geophone foundations with advanced optical interferometry to deliver ultra-low noise performance, 183 dB dynamic range, and industry-leading tilt tolerance that allows deployment in any orientation up to 180 degrees without leveling. Its product portfolio comprises three lines: the flagship Omnitilt analog optical sensor, the Digital Sensor System integrating precision sensors with double-digitization and an embedded Linux computer, and Custom Engineering Solutions for specialized mission-critical deployments.

Silicon Audio serves government seismic monitoring agencies, national laboratories, academic research institutions, and space agencies. Named deployments include the State of Texas TexNet program (nearly 100 seismometers deployed statewide for real-time earthquake detection down to magnitude 1.5), Los Alamos National Laboratory for nuclear nonproliferation monitoring, NASA's Artemis III lunar seismometer program (in collaboration with the University of Arizona and University of Maryland), Greenland-based icy worlds research with the University of Maryland, and Subsea Data Systems for SMART Cable seafloor integration targeting tsunami and earthquake early detection. Neal Hall serves as CEO and CTO, and the organization operates with 1-10 employees.

The business model combines hardware sales of optical seismometer units with custom engineering services for specialized deployments. Go-to-market is mission-critical enterprise sales through direct engagement with government agencies, national laboratories, and research institutions, with co-development partnerships with universities serving as a key channel for NASA-funded programs. No public pricing is disclosed; products are quote-based given their specialized nature. No funding rounds, M&A activity, or revenue figures are disclosed in the available data.

Core offering

Silicon Audio designs and manufactures interferometer-based optical seismometers used for high-sensitivity seismic and vibration sensing. The portfolio spans three offerings: analog optical sensors sold under the Omnitilt sub-brand, complete digital sensor systems, and custom engineering solutions tailored to deployments in extreme environments such as the ocean floor and the lunar surface. Sales are conducted business-to-business, primarily to government agencies, research institutions, and national laboratories.

Product overview

Silicon Audio offers a portfolio of interferometer-based optical seismometers comprising three product lines: the flagship Omnitilt analog optical sensor delivering high-sensitivity, low-noise performance with industry-leading tilt tolerance; the Digital Sensor System integrating precision optical sensors with double-digitization and embedded Linux computing for complete digital deployment capability; and Custom Engineering Solutions for specialized mission-critical deployments. These products share a common optical interferometry platform enabling deployment from ocean floors to lunar surfaces without leveling or performance compromise.
