Deepen Sinha
Director, Audio Development
Deepen Sinha leads all PAC (Perceptual Audio Coder) related technical activities for iBiquity Digital. In this role, he directs a team of engineers who are developing enhancements to iBiquity Digital's customized PAC algorithm, and preparing it for commercialization and deployment in various systems. Since joining iBiquity Digital (formerly Lucent Digital Radio) in 1998, Sinha has been instrumental in developing the company's customized version of PAC for use in the digital audio broadcasting arena, which includes features such as bitstream partitioning for unequal error protection, adaptive error concealment, and multistreaming techniques such as multi-descriptive and embedded coding.
Prior to joining iBiquity Digital, Sinha worked at Lucent Bell Labs, between 1993 and 1998, conducting research in the area of Audio Signal Compression. This work formed the basis for the latest generation of Lucent's Perceptual Audio Coder (PAC).
Sinha has contributed to a number of technical publications as well as a total of 19 awarded or applied patents in the areas of audio coding and joint source-channel coding.
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
