Abstract: The mass production of super-8 copies with an optical soundtrack started in Europe about 1970. Since then, a much better quality of the sound as well as of the image has been achieved through the improvement of the characteristics of the raw stock, improvement of the processing methods and improved quality control. A report on the state of the art at that time was given at the 1973 Audio Engineering Society Conference in Rotterdam. Since then further successful research has resulted in reducing the background noise of super-8 optical soundtracks by means of the Dolby-B method. A report on the subject was presented by the author at the 1974 AES Conference in Copenhagen.
