[. . . ] Note that if the click processor is still engaged you will also hear the removed click events. With lower thresholds, the crackle processor will detect high frequency portions of your signal and process these as crackle; this will be apparent when monitoring because you will be able to hear parts of your signal in the monitor signal. This is a good indication that the threshold is set too low. Basically, the monitored crackle signal should sound like random crackle events and should not resemble your input signal. If your signal is fairly percussive, it is likely that the crackle processor will detect the percussive onsets as crackle events. This will be audible in the monitor signal because you will hear the underlying rhythm. Your choices here are to increase the threshold, or to engage the onset bypass mechanism. To use the onset bypass, adjust the onset threshold until you see onset events (white lines in the display) that correspond to the underlying rhythm of your track. Lower thresholds result in more onsets events; higher thresholds reduce the number of onset events. Now enable the onset bypass by clicking on the BYPASS button. When monitored, you should hear that the crackles corresponding to musical onsets are no longer present, or at least reduced, when the onset bypass is engaged. 37 Wave Arts Master Restoration Suite It is unrealistic to expect that you will be able to remove all audible clicks and crackle without adversely affecting the sound of the original signal. A better strategy is to remove the most offending events, leaving the signal as untouched as possible. Because crackle is most audible during silent portions, say between tracks, one might be tempted to lower the threshold until all of the crackle is suppressed during these silent portions. But this is probably overdoing it, and there are other techniques which can be used to clean up the quiet portions. Both broadband noise reduction, as provided by MR Noise, and noise gating, as provided by MR Gate, can clean up the quite portions. Hence you should focus on removing the clicks and crackle that are audible while the music is playing. 5. 4 Parameters The table below lists all the internal parameters of MR Click and shows the range of values as would be displayed by a generic parameter-value plug-in interface. Most of these parameters have a one to one correspondence with controls on the user interface. Parameter name Enable Monitor Enable Click Enable Click Threshold Click Duration Crackle Enable Crackle Threshold Onset Bypass Onset Threshold Gain Monitor Gain Values 0 = Off, 1 = On 0 = Off, 1 = On 0 = Off, 1 = On 6 ­ 20 dB 0. 5 ­ 10 msec 0 = Off, 1 = On 12 ­ 40 dB 0 = Off, 1 = On 0 ­ 40 dB -12 to +12 dB -12 to +12 dB The parameters are described in more detail below. Enable -- This parameter is only available in the standalone MR Click, where it functions as the global bypass control. The Master Restoration plug-in does not have an enable for the Click & Crackle section. Monitor Enable -- This enables/disables the monitor feature. When monitoring is enabled, the output signal consists of the click and crackle signals that are removed by MR Click. Click Enable -- Enables or bypasses the click processor.
