![]() It was also necessary to invent the world's first audio card to be able to faithfully record and reproduce audio in the 20 Hz to 20,000 Hz range. that were based exactly on the same principle of psychoacoustics. This idea was the forerunner of other forms of compression that appeared later such as MP3, AAC, Opus, etc. ![]() This is a property of the human ear, known for many years, but without practical applications and which was used for the first time in this field. From his experience in the field of Psychoacoustics, Bonello considered that the solution to reduce digital data would be to transmit only a small fraction of it, selected to achieve masking of critical ear bands prevent noticing the absence of the missing information. This technology now named Perceptual Coding is the core of all the systems that we use every day to hear music using audio streaming. ![]() The Audicom required the creation of a data compression technology that could reduce the size of digital audio files. This invention has changed the way we today record and reproduce sound or listen to it via streaming. This technology was created in Argentina by a group of engineers led by Oscar Bonello, professor at the University of Buenos Aires, who began in 1982 to develop the idea of the digital recording on hard disk.
