 In the mid-1980s Solidyne, a broadcast manufacturer company, started the project of recording audio in a PC to automate the spots emission (at that time done by cartridges).By that time, the hard disk were very expensive and extremely small (a PC hard drive allowed 10MBytes of storage), so the engineers knew that they needed to develop a system to reduce the required bits as much as possible in order to be successful.The result was the ECAM audio system, the first system was shown to the 'Secretaria de Ciencia y Tecnica de la Nacion de la Republica Argentina' in 1988.
