Mono Distortion sums its stereo input to mono, performs distortion followed by a hipass filter and sends the result
as centered stereo.
L Input
R Input
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
R Input
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.

  • Page 37 FXAlg #908: Pitcher FXAlg #908: Pitcher Creates pitch from pitched or non-pitched signal Allocation Units: 1 This algorithm applies a filter which has a series of peaks in the frequency response to the input signal. The peaks may be adjusted so that their frequencies are all multiples of a selectable frequency, all the way up to 24 kHz. When applied to a sound with a noise-like spectrum (white noise, with a flat spectrum, or cymbals, with a very dense spectrum of many individual components), an output is produced which sounds very pitched, since most of its spectral energy ends up concentrated around multiples of a fundamental frequency.

When it is fed an impulsive sound such as a snare drum, LaserVerb plays the impulse back as a delayed train of closely spaced impulses, and as time passes, the spacing between the impulses gets wider.
  • Page 44 FXAlg #911: Mono LaserVerb ¥ FXAlg #912: LaserVerb Lite ¥ FXAlg #913: LaserVerb The output from LaserVerb can be fed back to the input. By turning up the feedback, the duration of the LaserVerb sound can be greatly extended. Cross-coupling may also be used to move the signal between left and right channels, producing a left/right ping-pong effect at the most extreme settings.

Both algorithms compress (reduce) the signal level when the signal exceeds a threshold. The amount of compression is expressed as a ratio.
  • Page 47 FXAlg #950: HardKneeCompress ¥ FXAlg #951: SoftKneeCompress To determine how much to compress the signal, the compressor must measure the signal level. Since musical signal levels will change over time, the compression amounts must change as well. You can control the rate at which compression changes in response to changing signal levels with the attack and release time controls.

  • Page 49 FXAlg #952: Expander FXAlg #952: Expander A stereo expansion algorithm Allocation Units: 1 This algorithm expands the signal (reduces the signalÕs gain) when the signal falls below the expansion threshold. The amount of expansion is based on the larger magnitude of the left and right channels. The amount of expansion is expressed as an expansion ratio.
  • Page 50 FXAlg #952: Expander The signal being expanded may be delayed relative to the side chain processing. The delay allows the signal to stop being expanded just before an attack transient arrives. Since the side chain processing ÒknowsÓ what the input signal is going to be before the main signal path does, it can tame down an attack transient by releasing the expander before the attack actually happens.

One version is followed by equalization and the other is not. The algorithms compress the signal level when the signal exceeds a compression threshold and expands the signal when the signal falls below the expansion threshold.
  • Page 55 FXAlg #954: Compress/Expand ¥ FXAlg #955: Comp/Exp + EQ To determine how much to compress or expand the signal, the compressor/expander must measure the signal level. Since musical signal levels will change over time, the compression and expansion amounts must change as well. You can control how fast the compression or expansion changes in response to changing signal levels with the attack and release time controls.

An expander may be used to suppress background noise in the absence of signal, thus typical expander settings use a fast attack (to avoid losing real signal), slow release (to gradually fade out the noise), and the threshold set just above the noise level.

  • Page 63 FXAlg #957: Gate ¥ FXAlg #958: Super Gate gate closes or opens after the gate timer has elapsed. The Signal Dly parameter delays the signal being gated, but does not delay the side chain signal. By delaying the main signal relative to the side chain signal, you can open the gate just before the main signal rises above threshold. ItÕs a little like being able to pick up the telephone before it rings! For Super Gate (not the simpler Gate), filtering can be done on the side chain signal.

The following is from an SRS Labs press release: SRS, the Sound Retrieval System, is based on the human hearing system. It produces a fully immersive, three- dimensional sound image from any audio source with two or more standard stereo speakers.
  • Page 77 FXAlg #966: Stereo Image FXAlg #966: Stereo Image Stereo enhancement with stereo channel correlation metering Allocation Units: 1 Stereo Image is a stereo enhancement algorithm with metering for stereo channel correlation. The stereo enhancement performs simple manipulations of the sum and difference of the left and right input channels to allow widening of the stereo field and increased sound field envelopment.

This algorithm allows you to view the current levels of any data sliders, MIDI controls, switches, or internally generated VAST LFOs, ASRs, FUNs, etc.
  • Page 85 FXAlg #999: Stereo Analyze FXAlg #999: Stereo Analyze Signal metering and channel summation utility algorithm Allocation Units: 1 Stereo Analyze is a utility algorithm which provides metering of stereo signals as its primary function. In addition to metering, the gains of the two channels are separately controllable, either channel may be inverted, and sum and differences to the two channels may be metered and monitored.
  • Page 86 FXAlg #999: Stereo Analyze By inverting one channel with respect to the other, you can hear what is characterized as Òphasey-nessÓ. Usually in stereo recordings, you can localize the phantom image of sound sources somewhere between the two loudspeakers. With a phasey signal, the localization cue get mixed up and you may hear the sound coming from everywhere or within your head.
