3. OdB to 99dB The ceiling parameter allows you to set an upper limit for the noise reduction process Levels that go beyond the ceiling will never be touched by the denoise process no matter what the captured or automatically generated fingerprint would remove Instead of setting the ceiling parameter you could of course also manipulate the fin gerprint in draw mode BIAS 20dB 20dB If the fingerprint does not perfectly represent your noise floor you can make further adjustments to the fingerprint with the Bias parameter This will increase decrease the fingerprint s noise level by up to 20dB TIP Bias can be especially useful when you are using a fingerprint from another recording i e when you are editing an existing preset based on a Fingerprint from another audio file As the Fingerprints do not completely match you may want to Bias the Fingerprint to meet the needs of a different audio file If your only chance to get a good fingerprint is during the fade out of your material you will want to increase the Bias value ATTACK 10ms TO 999ms To remove as much noise from your signal as possible use a short attack time 10ms Try increasing the attack time for softer processing for example if you are working with a less than ideal fingerprint CHARACTER Generally it is advised to leave the Character parameter at default the default setting will work in most cases When you consider the Character
4. parameter as an extreme fine tune parameter for the character of the Denoise algorithm you will be able to very subtly adjust the behavior of Denoiser Changing the Character will have an impact on the other parameters please get to know the conditions described below There is a psychoacoustic phenomenon where the reduction of noise will trick your ear into perceiving that the processed audio is darker or less brilliant than the clean signal This happens simply because the high frequencies from the noise are removed along with the noise This is especially true of Type 1 By selecting Type 2 the 14 RESTORATION SUITE Denoise algorithm will tuned to maintain the high frequency content but will be perceived as less noise reduction TYPE 1 Use less Reduction and faster Attack times generally less than 50 ms TYPE 2 Use more Reduction and slower Attack times generally over 100 ms SELECTING THE RIGHT CHARACTER How do these work together Let s assume the following example you are cleaning a dialog recorded in a small room Using Type 1 you will find that when Reduction is too great you may lose the perception of room ambiance and if the Attack is set to a longer value the space in between the dialog will slightly pump sounding unnatural In switching to Type 2 you may find less breathing artifacts in the dialog and a more consistent high frequency content but

6. by the processing If you can hear audio fragments in audition mode your settings are too extreme BYPASS By using the Bypass button for the Plug In instead of the host processing you may be interested to know that selecting the Plug In Bypass still includes the processing delay This is not the case when using the standard bypass button of your host application this will cause the playback to jump back and forth preventing you from accurately comparing processed and unprocessed audio RESTORATION SUITE s internal bypass function takes the latency into account allowing for hassle free comparison before and after processing 4 RESTORATION SUITE WAVEFORM DISPLAY OPTIONS Both the Declick and Descratch Plug Ins have Waveform Options to customize how the waveforms are displayed in the timeline of the Plug In Depending on the type of material you are working on you may find that you prefer one display to another even though no display method is better or more accurate than another TIP When selecting one of the Waveform Display Options this will be the default dis play behavior every time you open the plug in NORMAL DISPLAY Normal Display the default display mode is a high contrast scrolling waveform A clean waveform will appear black while click and scratch artifacts will be indicated with red lines These lines reflect the amplitude of the artifact signal large spikes imposed on the waveform will indicate clicks
