Sensicomm LLC was started in 2003 by Joe Rothweiler to provide research and development services in the areas of digital signal processing, speech and audio analysis, and general signal processing. Services include basic analysis, algorithm development, programming, and hardware design and development.

Clients have included Sirius Satellite Radio, Agere Systems (a department that is now part of Infineon), L-3 Communications, and various smaller and start-up companies.

Previously I worked in R&D at companies including Lucent and Sanders A Lockheed-Martin Company (now part of BAE Systems). Work included low-rate speech and audio coding, voice analysis and processing, and communication system design and simulation. Some highlights are a patent on the Polyphase Quadrature Filter bank, very low rate (1000 bps and below) speech coding algorithms, and work on the Sirius Satellite Radio audio compression components. See the Publications and Projects links above for more information about some past work.

Services

I provide DSP-related consulting services such as theoretical analysis, troubleshooting and problem solving on existing systems, reverse engineering of old designs, training and tutorials. Most projects are billed on a time & materials basis, but other contractural arrangements such as teaming, fixed-price, royalties, etc will be considered.

Projects have ranged in length from a few days to several months. Reasonable amounts of travel are OK.
