Résumé

Experiments in tonal as well in non-tonal contexts have shown the potential relevance of a proper model of roughness estimation in the framework of computer-aided composition environments. Two types of models are currently available that operate in either the spectral or the temporal domain. An experiment has been designed in which the respective influences of different cues have been pitted against one another using phase differences. Significant variation in roughness appeared between sounds with different temporal envelopes and roughness was generally linked to the rms value of the envelope. However, significant differences also appeared between sounds with the same spectrum and the same envelope but different temporal fine structure. This calls for a new modeling approach based on peripheral auditory processing.
