ARL Services

Patent Services Expert Witness, Litigation Support, Valuation, Due Diligence
ARL patent services are conducted by Dr. Schuyler Quackenbush, founder and President of Audio Research Labs. His technical expertice encompasses audio compresssion, signal processing, including audio and speech signal processing and real-time signal processing. In addition, he is an expert in MPEG audio standards.
Standardization Activities Attend Standards Meetings and Advocate for Client Positions
Dr. Schuyler Quackenbush, can attend meetings of standardization bodies and present and advocate for client positions or client technology. He is an expert in audio compression and has can easily represent technology in that area. As Chair of the MPEG Audio Subgroup, Dr. Quackenbush is extremely capable of advocating for MPEG technology, but would have to review situations in which advocating for client technology may appear to be adverse to MPEG technology.
Subjective Quality Evaluation Subjective Listening Tests
ARL staff have more than 20 years of experience in conducting subjective listening tests for evaluating the performance of speech and audio coding or processing technologies. We can perform BS.1116, MUSHRA, Comparative, or MOS tests on mono, stereo or 5.1 channel content, and presentation can be via either headphones or loudspeakers.
Engineering Consulting Signal Processing Algorithms
Our staff has more than 40 years of experience in developing real-time signal processing algorithms. Our specialty is audio, but we have done other media processing projects. Drawing on years of research know-how developed at Bell Laboratories, staff of Audio Research Labs can assist in or initiate the development of new client technology.

Custom Programming
Our staff are experts in real-time embedded programming, particularly in network-based applications. We are proficient in Java, C++, C and assembler language programming in many development environments, including Unix and Window, and are proficient in a multi-processing environment (threads, signals and pipes).
