 In 1976, sixteen of Caruso's recordings were among the first to be digitally remastered, using a ground-breaking process to improve the sound of the old acoustical recordings.The process was developed by Thomas G. Stockham at the University of Utah, and in 1978, RCA began a project to reissue all of Caruso's recordings on the RCA Red Seal label.Most Victrola LP releases beginning in the early 1970s were issued on RCA's "Dynaflex" vinyl format, which used thinner, more pliable, lighter-weight records.
