WAVE EDITOR / RECORDER
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
Ctrl+B inside the Editor, or use the
Tools > Spectral > Blur option.
- Amount - Adjusts the width of the convolution window; a greater amount means more blurring.
- Delay - Adjusts the offset between the source wave and the blurred section.
- Mix - Adjusts the level of the dry to wet signal.
- Use data outside selection - Only applies when a selection is made in the Editor sample edit window. This includes sample
data immediately outside and adjacent to the selected region to improve the blend between the selection and surrounding sample data.
- Accept - Applies the settings to the wave. To undo the blur, press
- 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.
- Preview - Audition the current settings.
- Accept - Process and paste (replace) the original selection.
