Curve options: parameter reference

Open a curve's menu with its small menu icon in the curve selector, or right-click its label away from the Dry/Wet bar. Select the curve itself to edit its Bezier shape.

These are native PsyPhaZ 1.1.05 menus. Each screenshot opens at full resolution. Tables follow the menu order; ranges describe the controls, and the displayed values are an example state. The close button at the top dismisses the menu.

Phase

The menu combines polarity, an all-pass shifter, spectral phase rotation and an octave-up effect. Their on/off switches let you use the sections separately.

Phase options, with the IIR filter type selected.

Parameter	Function and range
Inv L / Inv R	Invert the polarity of the left and right channels independently.
Toggle	Reverse both polarity switch states together.
IIR Shifter	Enable the all-pass filter shifter. Its Type can be TPT or IIR.
Type	TPT or IIR all-pass filter implementation. Q is available with IIR.
Stack	1–32 filters in series. More stages accumulate more phase shift.
Hz	20–800 Hz. Set the all-pass filter frequency.
Q	0.01–4. Resonance control for the IIR type; inactive for TPT.
Spread	−1 to +1. Offset the filter frequencies between the left and right channels.
use dry/wet	Apply the shifter using the Phase Dry/Wet contribution.
even if spectra off	Allow the enabled shifter to run when the spectral engine is disabled.
FIR Spectral	Enable the frequency-dependent phase rotation from the spectral curve.
Link / LR individual	Link the broadband rotations, or adjust the channels independently. With Link, L degrees also sets the right channel.
L degrees	−180° to +180°. Broadband rotation for the left channel, added to the frequency-dependent curve.
R degrees	−180° to +180°. Broadband rotation for the right channel. Inactive while Link is enabled.
Curve Depth	1–1000 multiplier for the frequency-dependent phase curve; the broadband offsets remain separate.
RT Octaver	Enable the spectral pseudo-octave-up effect.
Octave	0–1. Level of the octave-up component.
Base	0–1. Level of the original-pitch component.

TPT variant

The parameter list stays the same. Choosing TPT makes Q inactive; Hz, Stack and Spread still control the shifter.

Phase options with Type: TPT.

Parameter	Function and range
Type: TPT	Use the TPT all-pass implementation.
Q	Inactive for this filter type. Select IIR to adjust resonance.

Freq

Band Split defines the Sub, Mid and Hi regions used by band modulation. Eq scales the processed curve. Screen changes how the spectrum is displayed.

Freq options: Band Split, Eq and Screen.

Parameter	Function and range
Bass-Mids	20–20,000 Hz. Lower boundary between the bass and mid regions. The two boundaries are kept in frequency order.
Mids-Hi	20–20,000 Hz. Upper boundary between the mid and high regions.
Cross slope	0–1. Width of the crossover transition: smaller values make a harder transition; larger values spread it across more frequencies.
linear / constant power	Choose the band crossover weighting shape.
Eq → Max dB	0–36 dB. Gain represented by the top of the EQ curve. This changes processing.
Screen → Max dB	−24 to +24 dB. Upper limit of the spectrum display.
Screen → Min dB	−120 to −24 dB. Lower limit of the spectrum display.
Tilt	Adjust the frequency-dependent display tilt. The control displays the tilt in dB; its midpoint is approximately 3 dB per octave of visual compensation.
speed / avg	0.1–1. Spectrum display averaging: lower values give a slower, more averaged view.

See Phase and Freq for the band-pass Bezier example and cutoff square.

Correlator

The upper controls affect stereo processing. Averaging, view type and the comparison selector control the correlation analysis.

Correlator options.

Parameter	Function and range
Inv L / Inv R	Invert each channel’s polarity before the stereo-processing stage.
HAAS	Enable a delay on the right channel for the Haas effect.
haas ms	1–40 ms. Right-channel delay time when HAAS is enabled.
Mid / Side	−1 to +1. Adjust the mid/side balance: negative values favour mid, positive values favour side.
Pan	−1 to +1. Left/right output panning.
Mono src: L/R	Select the reference channel used when the correlation processing forces mono: off selects L, on selects R.
Speed / avg	0.1–1. Visual correlation averaging; lower values give a slower view.
Sym view type	Switch the correlation display representation. In the enabled view, green indicates in-phase values and orange out-of-phase values.
Sub max Hz	30–800 Hz. Upper frequency used for the low-frequency correlation average.
L vs R / SC vs Input monos	Compare left and right, or compare mono input with mono sidechain. The second option requires sidechain audio from the host.

Dynamics

The curve maps the detected envelope to a new level. Detector timing controls how quickly the input follows the signal; Amount blends the curve’s influence.

Dynamics options.

Parameter	Function and range
Peak / Rms	Choose peak or RMS level detection for the envelope that drives the curve.
In gain	−6.02 to +6.02 dB. Adjust the signal entering the dynamics detector and processing.
Attack	0.01–30 ms. Detector response to rising levels.
Hold	0.1–30 ms. Detector hold time.
Release	1–300 ms. Detector response to falling levels.
Make Up	Normalize the remapped envelope by the maximum height of the curve. This depends on the curve shape.
Amount	0–1. Scale the curve’s contribution together with the processor Dry/Wet setting.
Out gain	−6.02 to +6.02 dB. Output gain applied with the dynamics contribution.
Bezier normal / Bezier ultra	Choose the normal approximation or higher-resolution curve evaluation. Ultra uses more CPU.

Shaper

The curve maps audio sample amplitude directly. In gain changes how hard the signal drives the curve; Out gain sets its processed output level.

Shaper options.

Parameter	Function and range
In gain	−24 to +24 dB. Gain before the Bezier waveshaper.
Out gain	−12 to +12 dB. Gain after the Bezier waveshaper.
Make Up	Compensate for the maximum height of the curve by applying its inverse gain. This is curve-based compensation.
Bezier normal / Bezier ultra	Choose normal or higher-resolution Bezier evaluation.
oversampling	Upsample the signal before waveshaping, then downsample it afterward.
factor	2x, 4x, 8x or 16x oversampling. Higher factors require more CPU; the factor applies when oversampling is enabled.

Lfo 1

Lfo 2 has the same menu and parameters. The reference below applies to both LFOs; screenshots show Lfo 1.

The trigger mode and Sync duration belong to this LFO. The visualization, smoothing, look-ahead, transport style and audio-detector/filter settings are shared by Lfo 1 and Lfo 2.

Loop

Use Loop for a repeating, tempo-synchronized modulation curve.

Lfo 1 options in Loop mode.

Parameter	Function and range
Lfo 1	Select Loop, Midi (ch 2) or Audio. Loop repeats with transport; MIDI and audio events retrigger the curve.
Sync	Set the tempo-related duration of the curve. The grid offers 1/16, 1/12, 1/8, 1/6, beat, 1/3, 1/2, 2/3, bar, 1.5, 2 bars and 4 bars.
Visualize Trigger	Show the trigger/detector visualization in the scope. Shared by both LFOs.
Smooth ms	0.1–10 ms. Smooth modulation changes. Shared by both LFOs.
LookHead ms	0.1–10 ms. Look-ahead timing to compensate for detection/smoothing delay. This setting changes processing latency and is shared by both LFOs.
Transport	off, simple or fx. Choose the curve transport indicator style; shared by both LFOs.

Midi (ch 2)

Incoming MIDI note-ons on channel 2 restart the curve. Sync still sets its duration; this mode does not add detector controls. Route MIDI to PsyPhaZ in the host to use it.

Lfo 1 options in Midi (ch 2) mode.

Parameter	Function and range
Lfo 1: Midi (ch 2)	Retrigger this LFO from channel-2 note-ons.

Visualize Trigger	Show the trigger/detector visualization in the scope. Shared by both LFOs.
Smooth ms	0.1–10 ms. Smooth modulation changes. Shared by both LFOs.
LookHead ms	0.1–10 ms. Look-ahead timing to compensate for detection/smoothing delay. This setting changes processing latency and is shared by both LFOs.
Transport	off, simple or fx. Choose the curve transport indicator style; shared by both LFOs.

Audio

Audio transients restart the curve. This mode adds the Audio column; the left column keeps the controls documented under Loop. Filter controls remain visible when Pre-Filter is off, so you can prepare their settings before enabling it.

Lfo 1 options in Audio mode, including the detector and pre-filter.

Parameter	Function and range
Lfo 1: Audio	Retrigger this LFO from the shared audio detector.
Sync	Duration of each audio-triggered curve.
Visualize Trigger	Show the trigger/detector visualization in the scope. Shared by both LFOs.
Smooth ms	0.1–10 ms. Smooth modulation changes. Shared by both LFOs.
LookHead ms	0.1–10 ms. Look-ahead timing to compensate for detection/smoothing delay. This setting changes processing latency and is shared by both LFOs.
Transport	off, simple or fx. Choose the curve transport indicator style; shared by both LFOs.
Source	Audio SC uses the host sidechain; Audio Self uses the plugin input. Shared audio-trigger source.
Transients	0.1–1. Scale the transient detector used to retrigger the LFO. Use Visualize Trigger to inspect the detector against the scope’s trigger line.
Release ms	5–500 ms. Release of the detector’s envelope follower.
Pre-Filter	Filter the detector’s audio input to isolate the events that should trigger the curve.
Type	HP, LP, BP or AP: high-pass, low-pass, band-pass or all-pass detector filtering.
Freq	40–15,000 Hz. Pre-filter cutoff/centre frequency.
Q	0.5–3. Pre-filter resonance.
Show filtered	Show the filtered detector waveform in the scope.
Listen	Audition the signal received by the audio detector.

Start with Audio Self, enable Visualize Trigger, then adjust Transients while watching the scope. Use Pre-Filter to focus detection on a frequency region; disable Listen after auditioning the detector input.
