1.2   Product Overview

In Phase is an innovative, easy-to-use plugin that corrects phasing issues between tracks.Phasing can occur throughout the production process:

  • In recording, when multiple signals are combined: Like individual drum mics and overheads; guitar amps and DIs; and sources recorded with more than one
  • In mixing, when phasing issues that weren’t addressed during recording need to be
  • In mastering, when the final stereo mix has phasing

To help you restore phase coherence, InPhase features high resolution dual waveform displays; phase shift filters with adjustable frequency and Q; and an intuitive correlation meter which shows you just how much your tracks are in—or out of phase. You can move your waveforms manually or using the delay control, and even align them in relation to a sidechain input. InPhase includes mono, stereo, and dedicated live components, plus InPhase LT, a simplified version that gives you easy access to creative phase manipulation. Phasing can cause drops in volume and wreak havoc on your frequency response and stereo image; InPhase gives you the power to get your tracks back on track.

1.3   Concepts and Terminology

 Phasing is a phenomenon which occurs when two or more signals are summed together. For this reason, when discussing phasing issues, we are always referring to the relationship between two or more signals. InPhase uses all pass filters to correct phasing issues between tracks. An allpass filter is a signal processing filter that affects only the phase, not the amplitude of the frequency-response of a signal.. A 1st order allpass filter is defined by the frequency at which the phase shift is exactly 90°; a 2nd order filter is defined by the frequency at which the phase shift is 180° and by the rate of phase change, hence its Q factor.

1.4   Components

Wave Shell technology enables us to split Waves processors into smaller plugins, which we call components. Having a choice of components for a particular processor gives you the flexibility to choose the configuration best suited to your material. In Phase includes the following components:

  • InPhase Mono
  • InPhase Stereo
  • InPhase LT Mono
  • InPhase LT Stereo
  • InPhase Live Mono
  • InPhase Live Stereo
  • InPhase Live LT Mono
  • InPhase Live LT Stereo

Please note: All components have 20 ms latency, excluding Live components, which have no latency.

Chapter 2 – Quick Start Guide

There are three basic ways to work with InPhase:

  1. Using InPhase to correct the phase relation between two mono
  2. Using InPhase to correct the phase relation between the left and right channels of a stereo track.
  3. Using InPhase to align a stereo track to a sidechain

Detailed examples for each of the above scenarios are provided in the Appendix section of this manual. We recommend that you read through them in order to gain a basic understanding of the InPhase workflow. Video demonstrations of these examples are also available at www.waves.com.Additionally, the InPhase LT components may be used for creative phase manipulation.

Chapter 3 – Interface and Controls

3.1  Interface

3.2   Controls
  1.        Processing SectionsInPhase has two processing sections: In Stereo components, they are called Alpha and Beta; in Mono components, Alpha and SC.
  2.      Process ControlsIn Stereo components, the Alpha and Beta Process controls let us choose what to process. When CH1 is selected in the Alpha section, it will force CH2 to the Beta section. This setup is recommended for stereo tracks or dual mono tracks such as bass amp and bass DI. In Stereo components, when CH1/2 is selected in the Alpha section, the sidechain input is forced to the Beta section. This setup is recommended when processing signals in relation to a signal routed to the plugin via sidechain. In Mono components, the audio is forced to the Alpha section and the sidechain input is forced to the Beta section. This setup is recommended when processing signals in relation to a signal routed to the plugin via sidechain.Please note: In Logic and ProTools HD (TDM Mixer), sidechain functionality is not supported due to delay compensation and timing issues.
  3. Activity LED shows when there is input signal
  4. Gain controls the level of the signal going into the processing
  5. Phase Invert flips the phase by 180
  6. Phase Shift Curve Window displays the phase shift curve across the frequency line, and updates in real time as parameters change.
  7. .Type sets the phase shift filter type, and toggles between Off, Shelf (using the 1storder all pass filter) and Bell (using the 2nd order all pass filter.)
  8. Frequency selects the frequency at which the phase shift is 90° using the 1storder (Shelf) all pass filter or 180° using the 2nd order (Bell) all pass filter.
  9. Q sets the width of the 2nd order (Bell) allpass filter: A narrower Q results in afaster phase transition toward the selected frequency, leaving a larger portion of the frequency intact.
  10. Delay lets us move the signal up to 20 milliseconds in either direction. (Live components forward only.) We recommend adjusting the pure delay before addingany phase shift to the process
  11. .Monitor selects the output monitor configuration.o  When Stereo Mix is selected, the Alpha and Beta section signals, instereo, are monitored. (When CH1/2 in relation to SC is selected, monitored output signal is attenuated by 6 dB to compensate for the level increase caused by track summing.)o When Mono Mix is selected, the Alpha and Beta/SC section signals ,summed to mono, are monitored. (Monitored output signal is attenuatedby 6 dB to compensate for the level increase caused by summing tomono.)o When Alpha is selected, the Alpha section signal only is monitored.o When Beta/SC is selected, the Beta section signal only is monitored.
  12. Output LED displays the peak signal output level.
  13. Collapse closes the waveform display section.
  14. Capture has two modes, Automatic & Manual, which capture up to two seconds of signal at 44.1/48 kHz or one second at 88.2/96 kHz.o Automatic – When you click Capture, the mechanism will wait for a signal peak above -40 dBFS. When the first peak exceeds -40 dBFS, it will automatically capture the next one or two seconds (depending on the sample rate), and then stop.o Manual – Click Capture to begin capturing, and click it again to stop.In both modes, Capture time is limited to one or two seconds, depending on sample rate.
  15. Scroll Bar scrolls the x axis of the captured waveform.
  16. Correlation Meter displays the general correlation value metering between thecaptured Alpha and Beta waveforms, at the output of the delay and phaseprocessing applied. The values move between 1 and -1; the higher the value, thebetter the correlation.0 indicates no correlation between the signals.1 indicates maximum correlation (identical signals).-1 means the signals are completely out of phase.
  17. Correlation Markers display the maximum value of the correlation meter. Blue represents peak correlation value; orange represents negative peak value. If the negative correlation exceeds the positive, try flipping the phase on one of the sections.
  18. Correlation Value Box displays the current correlation value, and updates in real time.
  19. Zoom X zooms in on the x axis, at up to sample resolution.
  20. Reset Zoom resets the zoom to its default setting.
  21. Zoom Y Beta zooms in on the Beta section y (amplitude) axis.
  22. Beta Waveform is the waveform captured in the Beta section.
  23. Zoom Y Link links Zoom Y Alpha and Zoom Y Beta.
  24. Zoom Y Alpha zooms in on the Alpha section y (amplitude) axis.
  25. Waveform Displays show the captured waveforms. The display updates in real time according to the processing applied, excluding gain changes.
  26. Marker sets the center position for the zoom. Scrolling doesn’t change the marker position and, in certain situations, will place it outside the visible area. The marker also helps us align the peaks of the waveforms.Holding Alt/Option will help you move the Marker when the curser is on the waveform display.
  27. Copy Alpha Beta copies the plugin settings to the InPhase clipboard. to easly move settings between stereo and mono components.
  28. Paste Alpha pastes the settings of the Alpha section from the InPhase clip board.It is possible to paste the Alpha settings to the same plugin instance or to any other open In Phase plugin instance.
  29. Paste Beta pastes the settings of the Beta section from the InPhase clipboard. Inthe mono component, settings are pasted to the Alpha section. It is possible to paste the Beta settings to the same plugin instance or to any other open In Phase plugin instance.
