Perceptual Tolerances for Decay Parameters in Plucked String Synthesis
Hanna Järveläinen, Tero Tolonen · Journal of the Audio Engineering Society · 2001
The audibility of variations of decay parameters in plucked string synthesis was studied by a listening test. The decay was described by an overall time constant and a frequency-dependent parameter. Two fundamental frequencies, tone durations, and types of excitations were used for both parameters. The results indicate that variations between 25 and 40% in the time constant are inaudible. This suggests large perceptual tolerances for the decay parameters. The results are applied in model-based audio processing.
