Perceptual Study of Decay Parameters in Plucked String Synthesis
Tero Tolonen, Hanna Järveläinen · 2000
A listening experiment was conducted to study the audibility of variation of decay parameters in plucked string synthesis. A digital commuted-waveguide-synthesis model was used to generate the test sounds. The decay of each tone was parameterized with an overall and a frequency-dependent decay parameter. Two different fundamental frequencies, tone durations, and types of excitation signals were used totalling in eight test sets for both parameters. The results indicate that variations between 25 % and 40% in the time constant of decay are inaudible. This suggests that large deviations in decay parameters can be allowed from a perceptual viewpoint. The results are applied in model-based audio processing. 0
