This is an extensive report commissioned by UNESCO for its worldwide project Digi-Arts. It includes information on 191 composers from Argentina, 14 from Bolivia, 90 from Brazil, 39 from Chile, 39 from Colombia, 5 from Costa Rica, 44 from Cuba, 3 from the Dominican Republic, 11 from Ecuador, 5 from El Salvador, 6 from Guatemala, 73 from Mexico, 3 from Panama, 4 from Paraguay, 15 from Peru, 12 from Puerto Rico, 25 from Uruguay and 35 from Venezuela, who have been working with electroacoustic media in their music.

UNESCO also commissioned another report on the same subject: La música electroacústica en América Latina. More than simply English and Spanish versions of the same text, these are complementary writings on historical aspects of the electroacoustic music development in Latin America. Both reports are mostly available online at the Digi-Arts section of UNESCO web site.
