Tremolo

From Audacity Development Manual
Jump to: navigation, search
Tremolo modulates the volume of the selection at the depth and speed selected in the dialog. This is the same as the tremolo effect familiar to guitar and keyboard players.
Advice Note carefully that when you apply an effect to a time-stretched clip the changed speed of the clip will be automatically rendered.
  • If you apply an effect to a selection within a time-stretched clip then Audacity will split the original clip so that the selection can be rendered as part of applying the effect.
Alert If you apply this effect with an envelope present then there is a bug whereby the envelope is removed and the audio reverts to its full amplitude state prior to the effect being applied.

Waveform type

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).

Wet level (percent)

Sets the depth of tremolo. 0% is no tremolo, 100% sweeps between zero and maximum volume based on the original amplitude level.

Frequency (Hz)

Controls the speed of the oscillation; use higher frequencies for faster oscillation.
