Abstract:
1. A method for providing sound generation instructions from a digitized input signal, said method comprising: transforming by use of time-frequency transformation at least part of the digitized input signal into a feature representation, extracting characteristic features of the obtained feature representation, comparing at least part of the extracted characteristic features against stored data representing a number of signal classes, selecting a signal class to represent the digitized input signal based on said comparison, selecting from stored data representing a number of sound effects sound effect data representing the selected signal class, determining sound volume data from stored reference volume data corresponding to the selected signal class and/or sound effect and from at least part of the obtained characteristic features, and generating sound generation instructions based at least partly on the obtained sound effect data and the obtained sound volume data, said method being characterised in that for a selected signal class the corresponding stored reference volume data is at least partly based on a number of training maximum amplitudes obtained at corresponding peak frequencies during a preceding training process including generation of several digitized input signals, each said digitized input signal being based on one or more generated signals to be represented by the selected signal class.
