An Additive Synthesis Technique for Independent Modification of the Auditory Perceptions of Brightness and Warmth

An algorithm that achieves independent modification of two low-level features that are correlated with the auditory perceptions of brightness and warmth was implemented. The perceptual validity of the algorithm was tested through a series of listening tests in order to examine whether the low-level modification was indeed perceived as independent and to investigate the influence of the fundamental frequency on the perceived modification. A Multidimensional Scaling analysis (MDS) on listener responses to pairwise dissimilarity comparisons accompanied by a verbal elicitation experiment, examined the perceptual significance and independence of the two low-level features chosen. This is a first step for the future development of a perceptually based control of an additive synthesizer.
