Blur Tool

The Blur Tool works in a similar way to the Convolution Reverb, by multiplying an impulse sound (in this case, noise), with the waveform. The impulse function is cross-multiplied with the source in a moving average, to smear or 'blur' the sound. The multiplier function is determined by a user-selectable envelope. To retain a sound closer to the original, use narrower shaped envelopes.

To Open the Blur Tool

To open the tool you can either Left-click on the Blur Tool button , press Ctrl+B inside the Editor, or use the Tools > Spectral > Blur option.



Envelope - Change the shape of the envelope to adjust the convolution function. The default 'Gaussian' function creates a smooth blur. A wider function generally creates more blurring and a narrower function less blurring. Experiment with different shapes to alter the blur texture.
