I want to know the answer to the following question:
Who was an engineering professor at the University of Buenos Aires?
All the background I'm provided with is that "In 1983, using the psychoacoustic principle of the masking of critical bands first published in 1967, he started developing a practical application based on the recently developed IBM PC computer, and the broadcast automation system was launched in 1987 under the name Audicom.". Is that enough to answer the question?
