Hiss & Continuous Noise Reduction
This process will attenuate continuous noises that remain in your file via the Continuous Noise Filter (CNF). Numerous noise fingerprints (or noise signatures) are pre-programmed into the system based on record type. The Wizard will ask you a series of questions which will then bring up the appropriate CNF settings with a good starting point set of noise contours and filter parameters. Preview the file using this filter that was the result of the previous restoration steps. You can tweak the effect of the CNF per your taste, with the attenuation control having the greatest impact on your results. Higher settings of attenuation produce greater degrees of noise reduction, but when set too high will introduce artifacts into your file. Experiment with this control to obtain the best balance between noise reduction and artifact production. When you are satisfied with the CNF settings using “Preview” mode, run the filter. Depending on how you answer the questions for Step 3, one of the following presets will be selected from the CNF Presets listing:
33 RPM LP Starting Point
45 RPM Starting Point
78 RPM Acoustical Starting Point
78 RPM Electrical Starting Point
80 RPM Vertical Cut Starting Point
160 RPM Vertical Cut Cylinder Starting Point
*General Purpose (Flatline Response) Starting Point
Note: Alternatively, these presets can be accessed directly via the CNF presets selection field.
*Note: This preset is not available via the Wizard, but can be found directly in the CNF itself. It is good for unusual record types, like acetates.
