摘要： A method and a system for providing sound generation instructions from a digitized input signal are provided. The invention comprises transforming 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, and selecting from stored data, which represents a number of sound effects, sound effect data representing the selected signal class. Sound volume data is determined 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 sound generation instructions are generated based at least partly on the obtained sound effect data and the obtained sound volume data. It is preferred that the sound generation instructions are forwarded to a sound generating system, and that a sound output corresponding to the digitized input signal is generated by use of said sound generating system and the sound generation instructions. The transformation of the digitized input signal into a feature representation may include the use of Fourier transformation, and the extraction of the characteristic features may com- prise an extraction method using spectrum analysis and/or cepstrum analysis. For each signal class there may be corresponding reference volume data.
