Abstract
Method and apparatus for processing compressed, stored analog signals, such as audio signals, from a storage medium, including first converting the signals to digital signals and thereafter expanding the signals. To realize a large volume range in the conversion of compressed recorded signals to expand digital signals, the compressed analog signals picked up from a storage medium are initially analog/digital converted and only then digitally expanded.
