Abstract
A sound processing system is provided in which a sound signal is stored in a sound data storing unit in the form of digital sound data. The digital sound data is analyzed to obtain a physical feature quantity of the sound signal. Index data indicative of a quantity feature of the sound signal is generated by discriminating a physical feature quantity of the sound signal, and it is stored in an index data storing unit. The digital sound data is processed in accordance with the index data by a data processing unit.
