Determines the "shape" of each tremolo (how it progresses between the lowest and highest volume as determined by the wetness level). Choice of sine, triangle, sawtooth, inverse sawtooth, square.
Starting phase (degrees)
Sets where to start the tremolo in the waveform cycle. The default (zero) starts the tremolo at the start of the cycle (as the waveform starts to rise from the lowest point).
Wetness level (percent)
Sets the depth of tremolo. 0% is no tremolo, 100% sweeps between zero and maximum volume based on the original amplitude level.
Controls the speed of the oscillation; use higher frequencies for faster oscillation.
Clicking on the command buttons give the following results:
- Manage presets. gives a dropdown menu enabling you to manage presets for the tool and to see some detail about the tool. For details see
- plays a short preview of what the audio would sound like if the effect is applied with the current settings, without making actual changes to the audio. The length of preview is determined by your setting in , the default setting is 6 seconds.
- Nyquist plug-ins.
applies the effect to the selected audio with the current effect settings, but unlike the effect runs in debug mode. This is primarily of use when writing or editing
- In addition to the normal plug-in behavior, a "debug window" opens to display error messages, normally the debug window will be empty.
- applies the effect to the selected audio with the current effect settings.
- aborts the effect and leaves the audio unchanged.
