Dr. Deepen Sinha
Dr. Sinha has been focused in the area of audio compression technology for over a decade. He serves ATC Labs as the President. He has contributed to a number of technical publications in the area and is an inventor of over 20 awarded or applied patents on audio coding and joint source-channel coding. He started his career in AT&T Bell Labs research in 1993, where he contributed to the early versions of AT&T Perceptual Audio Coder (PAC) and developed a multi-channel version of PAC. In 1995, after the split of AT&T, Dr. Sinha transitioned to Lucent Technologies Bell Labs and between 1995 and 1998, was the principal researcher for Lucent in the Audio Signal Compression area. His work there formed the basis for the latest generation of Lucent's PAC Codec.
Between 1998 and 2003, he worked at Lucent Digital Radio and its successor iBiquity Digital, and during this time focused on 3 main areas: (i) improving PAC audio quality at bit rates below 64 kbps, (ii) Statistical Multiplexing for multi-program audio broadcasting, and, (iii) Multistreaming for robust broadcast quality under channel impairments, e.g., interference. During this time he led an integrated team of 10 research and development engineers. A primary achievement of this team was the development and integration of the PAC4 codec (an upgrade to Lucent PAC), and the statistical multiplexing technology into the Sirius Satellite Radio system.
Since the formation of ATC Labs, Dr. Sinha has focused on developing novel techniques for exploiting signal redundancies to achieve high audio quality at very low bit rates. He has also worked on developing a deeper understanding of Perceptual Modeling and quantization issues in audio codecs related to certain type of signals which present unique challenges such as vocals and some tonal instruments.
Deepen Sinha earned a B.Tech (Hons.) degree in Electronics & Electrical Communications Engineering from the Indian Institute of Technology, Kharagpur, India, in 1986, a M.S. degree in Electrical Engineering from Iowa State University in 1989, and a Ph.D. in Electrical Engineering from University of Minnesota, Minneapolis, in 1993. His Ph.D. dissertation made original contributions to the idea of wavelet based audio coding.
