Procesos de tratamiento y análisis de sonido aplicados a registros sonoros de archivos de radio

Abstract

For a few decades, the preservation of audiovisual documents in analogue format –mechanical and/or electrical– has experienced a boost thanks to the technological progress of developed societies in areas related to the acoustic processing of signals and all aspects of what is universally known as the “digital world”. This article shows the results of a methodology that, from the perspective of digital audio analysis, reconciles the stipulations in international guidelines and available resources, while also meeting the quality levels specified in those regulations, but with less technical requirements than those that are officially recommended.
