Summary on Grant Application Form
To develop software for real-time synthesis of complex sounds for psychoacoustic experiments. To investigate the perception of pitch and timbre in complex musical and speech-like sounds.Progress: We have shown that coherent frequency modulation helps to group a mistuned harmonic into a complex sound for the purpose of calculating its pitch, but not for the purpose of calculating its vowel quality.We have shown that coherent amplitude modulation does not help to group a mistuned harmonic into a complex sound for the purpose of calculating its pitch. We have shown that auditory models can help to explain the interaction between the choice of instrumentation in orchestration and the intervals being played by the instruments-. We have shown that pairs of instruments are easier to recognise when they are playing on different pitches than when they are playing on the same pitch. The improvement with identification as a function of pitch difference is very similar for pairs of instruments as found previously for pairs of vowel sounds. We have shown that as a harmonic of a natural cello or oboe note is progressively mistuned, it shows a similar change in contribution to the pitch of the note as it does for an artificial flat-spectrum sound.Refereed journal articlesDarwin, C.J., Ciocca, V. and Sandell, G.R.
