Risset Drum
From Audacity Manual
Risset Drum produces a sound based on work by the composer of electronic
music, Jean Claude Risset. It consists of band-pass filtered noise, an enharmonic tone and a relatively strong sine wave at the fundamental.
Frequency (Hz)
The pitch of the drum note expressed in Hz. This tunes the "fundamental frequency" or "base note" of the sound.
Decay (seconds)
Determines the length of the drum sound. Longer sounds can sound similar to a gong.
Center frequency of noise (Hz)
The center frequency of the band-pass filter that is applied to the noise. Higher frequencies can sound as if small cymbals are vibrating with the drum stroke.
Width of noise band (Hz)
The minimum width of the band-pass filter that is applied to the noise. Higher values can increase the impression of a gong sound.
Amount of noise in mix (percent)
The amount of noise in the drum sound as a percentage of the mix. Values near maximum can sound like a gun shot if other controls are left at default values.
Amplitude (0-1)
The peak amplitude of the generated sound.
