1997-2000 - Liquid Audio, Redwood City, California - Chief Scientist and Manager of Authoring Tools and DSP Group. Architect of company's audio and signal processing technology. Implemented, optimized, and/or integrated all the signal processing components in Liquid Audio's system: audio codecs (MP3, AAC, ATRAC3, AC-3, Lossless), audio watermarking, equalization, dynamic compression, sample rate conversion, etc. Inventor of majority of company's intellectual property, with 11 patents filed. In management role, led engineering and testing teams that developed industry-leading authoring tools (encoding) products for Windows, Macintosh, and command-line (DOS and Unix) platforms. Participated in entire life-cycle of development of three major releases of the system of server, client, and authoring tools. Frequent mentor and advisor to entire engineering team. Software work done using C++ / object-oriented design in cross-platform development environment (Microsoft Developer Studio, Unix, Macintosh). Architect of build procedures and source code control administrator and guru. Technical evangelism: lectured on AAC audio codec (at Audio Engineering Society) and watermarking (at UC Berkeley). Participation in MPEG standards committee.
1997 - Vxtreme, Inc., Sunnyvale, California - Senior Engineer, Compression Group. Research and development for video and audio compression components of internet streaming media technology. Thorough knowledge of video and audio compression systems (H.263, HVQ, CELP, G.723.1, TwinVQ) as well as general signal processing methodologies (resampling, color conversion, preprocessing) and real-time streaming over the internet. Involvement in the MPEG standards committee. Software implementation, integration, and optimization using C++ / object-oriented design in cross-platform development environment (Microsoft Developer Studio and Unix). In August 1997 Vxtreme was acquired by Microsoft and integrated into its Windows Media (then called Netshow) division in Redmond, WA.
