Resumo
A new method for interactive sound synthesis based on the application of genetic algorithms is presented. This method generates sequences of waveforms through the application of genetic operators on an initial population of waveforms. The waveforms are suitable to be played by a conventional wavetable synthesizer engine. We describe how the waveforms can be treated as genetic code, the fitness evaluation methodology and how genetic operations such as crossover and mutation are used to generate new waveforms. Finally, we discuss the results evaluating the generated sounds.
