Hello Jyrki, If I understand you, the VTL discrimination experiments in two of our recent publications (below) are the sort of thing you are looking for. They employ speech stimuli, but they will give you an idea of how to conduct CofG experiments and how to manipulate the stimuli with STRAIGHT. A CogC shift on a log-frequency axis corresponds to a change in source size in these stimuli. Cheers Roy P Smith, D. R. R., Patterson, R. D., Turner, R., Kawahara, H., and Irino, T. (2005).

"Discrimination of speaker size from syllable phrases," J. Acoust. Soc.
