L Input Distortion L Output R Input Block diagram of Mono Distortion R Output MonoDistort + EQ is similar to Mono Distortion except the single hipass filter is replaced with a pair of second-order hipass/lowpass filters to provide rudimentary speaker cabinet modeling. The hipass and lowpass filters are then followed by an EQ section with bass and treble shelf filters and two parametric mid filters. L Input Distortion Cabinet EQ L Output R Input R Output Block diagram of MonoDistort + EQ StereoDistort + EQ processes the left and right channels separately, though there is only one set of parameters for both channels. The stereo distortion has only one parametric mid filter. L Input Distortion EQ L Output R Input Distortion EQ R Output Block diagram of StereoDistort+EQ Algorithm Reference-94 FXAlgs #724-6, 728: Distortion MonoDistort + Cab is also similar to Mono Distortion except the hipass is replaced by a full speaker cabinet model. There is also a panner to route the mono signal between left and right outputs. [. . . ] The higher feedback is set, the longer the decay or echo will last. LaserVerb & LaserVerb Lite are stereo effects. The cross-coupling control lets you send the sum of the input and feedback from one channel to its own LaserVerb effect (0% cross coupling) or to the other channelÕs effect (100% cross coupling) or somewhere in between. This control is not available in Mono LaserVerb. The damping of high frequencies relative to low frequencies. When set to the highest frequency (25088 Hz), there is no damping and all frequencies decay at the same rate. At lower frequency settings, high frequency signal components will decay faster than low frequency components. If set too low, everything will decay almost immediately. The Pan control is available in the Mono LaserVerb. The left and right inputs get summed to mono, the mono signal passes through the LaserVerb, and the Þnal mono output is panned to the left and right outputs. Panning ranges from -100% (fully left), through 0% (centered), through to 100% (fully right). You can set the overall delay length from 0 to 2 seconds (3 PAU) or 0 to 1. 3 seconds (2 PAU). Lengthening the delay will increase the duration or decay time of the reverb. To reduce LaserVerb to a simple delay, set the Contour and Feedback controls to 0. Use a delay of about half a second as a starting point. The delay Þne adjust is added to the delay coarse adjust to provide a delay resolution down to 0. 1 ms. Determines the starting pitch of the descending buzz and how fast it descends. The Spacing parameter sets the initial separation of impulses in the impulse response and subsequent rate of increasing impulse separation. The spacing between impulses is given in samples and may be a fraction of a sample. (A sample is the time between successive digital words which is 20. 8 ms or 1/48000 seconds. ) For low values, the buzz starts at high frequencies and drops slowly. At high values the buzz starts at a lower pitch and drops rapidly. Controls the overall envelope shape of the reverb. [. . . ] If you find that parts of your mix disappear or start to sound metallic (comb filtered), you may have to go back and do some work on your mix. The difference signal (L-R)/2 provides a measure of the stereo content of your mix and can be very indicative of mixing style. Listening to the difference signal of someone elseÕs recordings can often demonstrate interesting techniques (and mistakes!) in stereo production. The difference signal contains everything that doesnÕt make it into the mono mix. [. . . ]
