Quality Control in the Radio Nacional de Espana Sound Archive Digitization Process

摘要

The 20th century Spanish sound history can now be consulted online. This is a pioneer project in the broadcasting industry around the world. The Radio Nacional de Espana (RNE) sound archive has been massively digitized and several applications to access this information online have been developed. This archive is considered the most important audio archive in Spanish language in the world. Special innovation has been used in developing a statistical model to estimate the probability of error in the digitisation process, for a given confidence probability. Several kinds of errors have been considered, like human errors, mechanical errors, software errors or support errors. The results of the statistical model allows to say that the probability of error is lower than 0.3% for a confidence probability of 99.999%.
