Before coming to UCSB I had a good long stint in the industry at Ittiam. As part of the audio team I was involved in audio codecs development, audio effects development, platform specific audio development and development process standardization.
During my undergrad I did my final year project with TI and Prof. Sumam David, developing the iLBC speech codec for the TI C55x DSP.
