Overview

The Intelligibility meter uses inter plug-in communication to receive audio data from Relay plug-in instances to allow for the monitoring of dialogue intelligibility in the context of different listener environments.

Intelligibility meter

Configuration

The following steps outline the setup and recommended configuration for the Intelligibility meter:

  • Insert Insight 2 on the master bus.
  • Insert Relay on a dialogue bus or track.
    • Relay should be inserted on the bus or track that is feeding into the master bus. e.g. if multiple tracks are being sent to a dialogue submix which is then routed to the master bus, insert Relay on the dialogue submix rather than the individual dialogue track.
    • If other plug-ins are inserted on the dialogue bus, add Relay to the last available insert slot.
    • For the best results, ensure that Insight 2 and Relay are inserted on tracks the use the same channel configuration. e.g. Insight 2 is inserted on a 5.1 master bus, Relay is inserted on a 5.1 submix bus.
  • In the Intelligibility meter panel, select the Relay instance on the dialogue bus in the source list. Click “Ok” to dismiss the source list view. Source list

Overview

The Loudness panel includes measurements used to ensure loudness compliance when delivering media for broadcast TV or streaming services. Loudness measurements are based on the ITU-R BS.1770 recommendation , which defines audio measurement algorithms for determining true peak signal level and subjective loudness over the course of a program.

The Loudness meter panel features dynamic view configurations based on the height of the meter, loudness measurements, common loudness standard target presets, and a Targets control panel for customizing meter targets and the loudness measurement Gate mode.

Loudness meter panel

Views

There are two possible views available in the Loudness meter panel: minimized and maximized. These views are shown dynamically based on the height of the Loudness meter panel.

Minimized view

The minimized view configuration is dynamically loaded when the height of the Loudness meter panel is less than 270 pixels. The meter bars are hidden in minimized view to provide a compact overview of loudness statistics.

Loudness meter minimized view

Maximized view

The maximized view configuration is dynamically loaded when the height of the Loudness meter panel is equal to or greater than 270 pixels. The meter bars are displayed alongside the text readouts in maximized view configuration to provide a full overview of loudness statistics.

Measurements

The following image outlines the measurements available in the Loudness meter panel:

Loudness meter measurements

Short-term

Measures loudness over the course of 3 seconds. Short-term measurements are useful for monitoring immediate trends in loudness. Short-term loudness measurements are never gated, regardless of the currently selected Gate option in the Targets control panel.

Short-term loudness displays

Integrated

Measures loudness over an indefinite period of time, including any selected Gate threshold. Integrated loudness is an infinite average that generates a single value for the entire duration of the calculation. When the Dialogue Gate is selected, a “(DIA)” label will be displayed next to the Integrated label to indicate that it is a dialogue-gated measurement.

Integrated loudness displays

Dialogue-Gated Integrated Measurements

The Integrated measurement displays will be delayed in updating for the first two seconds of the Dialogue-gated loudness measurement, even if there is dialogue present in the source material. After the initial two second delay, the Dialogue-gated Integrated measurement will only begin to update if/once dialogue content has been detected in the source material.

Dialogue Content Percentage

Displays the percentage of dialogue detected in the source material over the entire duration of a Dialogue-gated loudness calculation. This measurement represents the ratio of detected dialogue content to the total content in the source material. The presence of dialogue is determined in slices of 500 milliseconds and the percentage is updated throughout the entire duration of the calculation.

Dialogue Content Percentage Readout

Dialogue Content Percentage Availability

The Dialogue Content Percentage measurement is only visible when the Dialogue Gate option is selected in the Targets control panel.

Momentary

Measures loudness over the course of 400 milliseconds. Momentary loudness measurements are never gated, regardless of the currently selected Gate option in the Targets control panel.

Momentary meter bar

Momentary Measurement in Minimized View

When the minimized view configuration is active, all loudness meter bars are hidden from view. Increase the height of the Loudness meter panel to access maximized view or utilize the Momentary loudness trace in the History meter panel to monitor Momentary loudness activity.

Momentary Maximum

    • Down Arrow Key: Decreases the LRA target range by adding 1 LU to the minimum value and subtracting 1 LU from the maximum value with each key press.

Gate

There are three different gating options for loudness calculations in the Loudness meter panel: Off, Dialogue, and Program. Gating is employed in loudness measurements in order to exclude quieter sections of a program from lowering the overall loudness measurement (Program-gated) or to measure the loudness of a program using dialogue as an anchor element (focal point) for the loudness calculation (Dialogue-gated).

Loudness meter Gating options

Off

When Off is selected, no gating method is enabled when calculating loudness. When selected, the loudness measurements are based on the BS.1770-1 recommendation, which did not employ the -10 LU relative program gate.

Dialogue

Enables a loudness gating method that detects if dialogue is present in the source material. Only segments of the program where dialogue is detected will contribute to the Integrated loudness measurement. When selected, the loudness measurement is based on the ITU-R BS.1770-1 revision . The -10 LU relative program gate threshold is not when the dialogue gate is enabled.

Dialogue-Gated Loudness: Initial Drawing Delay

  • The algorithm used to calculate dialogue-gated loudness requires at least two seconds of incoming audio in order to begin detecting dialogue content in the input signal.
  • This two second delay can be observed in the initial drawing of the following measurements:
    • Dialogue-gated Integrated measurements in the Loudness meter panel.
    • The Short-term, Momentary, and Integrated loudness traces in the History meter panel.
  • This delay does not affect the accuracy of the loudness measurements.

Program

Enables a -10 LU relative gating threshold when calculating loudness in order to exclude lower level noise from decreasing the overall loudness measurement of a program. The BS.1770-2/3/4 revisions of the ITU-R BS.1770 recommendation requires that a -10 LU relative program gate threshold is applied when calculating integrated loudness.

Calculation Settings

Controls for resetting, pausing or holding loudness meter calculations are located in the header of the Insight plug-in window.

NameDescription
Loudness calculation settings - ResetResetManually resets all loudness calculations in the Loudness and History meters.

To drag a given scale simply click anywhere on the scale and drag it in the desired direction. Double-click on either scale to return to the default view.

Options

The Spectrum Analyzer includes the following options:

Spectrum Analyzer Options

  • Spectrum Type: Selects between 4 different types of spectrums.
    • Linear: a continuous line connecting the calculated points of the spectrum.
    • 1/3 Octave: Splits the spectrum into bars with a width of 1/3 of an octave. Although the spectrum is split into discrete bands, this option can provide excellent resolution at lower frequencies.
    • Full Octave: Splits the spectrum into bars with a width of one full octave.
    • Critical Bands: Splits the spectrum into bands that correspond to how we hear, or more specifically how we differentiate between sounds of different frequencies. Each band represents sounds that are considered “similar” in frequency.
  • Average Time: Spectrum is averaged according to this setting. Higher average times can be useful for viewing the overall tonal balance of a mix, while shorter average times provide a more “real time” display.
  • Peak Hold Time: Selects between specific hold times in milliseconds, or Infinite, where the peak is held indefinitely.
  • Window Size: Controls the trade off between frequency and time resolution in the spectrum. Higher values will let you see smaller peaks in the spectrum, but the spectrum will update more slowly.
  • Window: Selects a window type for the spectrum. In most cases the default window type will work well, but you can choose from a variety of window types. Each window type has different amplitude and frequency resolution characteristics.
  • Overlap: Controls how often the spectrum updates. More overlap will cause the spectrum to update more frequently, at the expense of increased CPU usage.
  • Show Peak Hold: Turns the peak hold display on/off.

Overview

The Sound Field meter panel features a stereo vectorscope and a surround scope meter.

Vectorscope

A Vectorscope is a meter that juxtaposes the two channels of a stereo signal on an x-y axis in order to display the similarity or difference between the two channels. A mono signal will produce a straight vertical line while signals with a wider stereo image will produce more horizontal shapes. A Vectorscope can be used to monitor the stereo width of a signal while mixing or mastering. It can also help to highlight potential issues with phase cancellation.

The following view modes are available in the stereo vectorscope:

  • Polar Sample
  • Polar Level
  • Lissajous

Sound Field Modes

Polar Sample

The Polar Sample Vectorscope plots dots per sample, but uses a polar coordinate display that is more useful in highlighting the stereo image of the incoming signal. Patterns that appear within the 45-degree safe lines represent in phase signals while patterns outside these lines represent out of phase audio. The history of the Polar Sample Vectorscope also fades out slowly. The infinite history is shown as the faintest shade of grey while the last few seconds are displayed as slowly fading data points. You can reset the display by clicking on the meter.

Polar Sample view

Polar Level

The stereo energy of a recording is clearly represented by the Polar Level Vectorscope which plots rays on a polar coordinate display that represent sample averages. The length of the rays represents amplitude while the angle of the rays represents their position in the stereo image. Rays within the 45-degree safe lines represent in phase audio while anything beyond these lines represents audio that is out of phase. History is represented on the Polar Level Vectorscope with the shrinking of the plotted rays slowly over time. The rays shrink towards the center of the vectorscope leaving the outer portion of the display for real-time analysis.

Polar level view

Lissajous

Like the Polar Sample vectorscope, the Lissajous Vectorscope plots per sample dots on a traditional oscilloscope display. Typically, stereo recordings produce a random pattern on a Lissajous Vectorscope that is taller than it is wide. Vertical patterns mean left and right channels are similar (approaching mono, which is a vertical line). Horizontal patterns mean the two channels are very different, which could result in mono compatibility problems.

Lissajous view

The history of the Lissajous Vectorscope fades out slowly. The history is shown as the faintest shade of grey while the last few seconds are displayed as slowly fading data points. You can reset the display by clicking on the meter.

Clipping

The Vectorscope will draw any clipped samples in red.

Balance Meter

The horizontal bar meter below the stereo vectorscope display indicates the averaged stereo location of the input signal.

Correlation Meter

The vertical bar meter to the right of the stereo vectorscope display indicates the amount similarity (or correlation) between the left and right channels. When two signals are exactly the same (in phase) a reading of +1 would register on the correlation meter. When two signals are perfectly out of phase and thus completely different a reading of -1 would register on the correlation meter.

A Correlation Meter is used in stereo to ensure that the left and right signals will sum to mono without any cancellation of frequencies. If two signals are perfectly out of phase, then summing them would result in no audible audio. Typically, mixed audio will have values between 0 and +1 depending on the width of the stereo signal. Values that dip briefly below zero do not necessarily represent serious problems with your audio, but prolonged negative readings indicate issues with mono compatibility.

Surround Scope

The Surround Scope is a stylized display of the amplitude of surround channels. This display stresses the spatial relationship of the channels while still illustrating the level of each channel. The Surround Scope monitors the phase relationship between neighboring audio channels and displays an alert when there is a negative correlation or phase cancellation taking place.

surround scope view

Surround Amplitude

The Surround Amplitude Meter plots rays within a 360 degree readout with markers designating the various surround channels.

Surround Balance Indicators

The Surround Balance Indicator displays a tracking dot in different locations on the 360 degree readout. The location of the dot represents the summed surround location of all channels.

Surround Correlation Alerts

Correlation Alerts which bring your attention to any potential issues of phase between neighboring channels. The cells bordering the 360 degree plot of the Surround Scope each represent a given channel relationship. Only prominent signals that are significantly out of phase will trigger the alerts.

Surround Meter Scale

The rings within the meter represent precise RMS signal levels of each of your channels. Signals below -60dB RMS will not register as vectors on the Surround Meter.

Overview

The global options window includes the following sections: General, Loudness, Updates, and Authorization. These options save to a configuration file, which means that modifications to the factory default values will persist in new instantiations of Insight 2.

Global Options Window

The buttons along the bottom of the Global Options window include:

  • Reset: Resets all options to their factory default settings.
  • Cancel: Discards changes made since last opening the global options window and closes the window.
  • Ok: Saves changes and closes the global options window.

General

  • Show tooltips: Enables/disables the display of tooltip text.
  • Send anonymous usage data: Enables sending of anonymous usage data to iZotope to help improve Insight 2.

Loudness

  • Enable automation data: When checked, Insight 2 will broadcast loudness overflow and integrated loudness automation data to the DAW/NLE. Enable track automation in the DAW/NLE to write the loudness data to two automation envelopes.
    • Loudness overflow: When the integrated loudness target has been exceeded, this will broadcast a value of “True”, or “1”. When the integrated loudness level is below the target, this will broadcast a value of “False” or “0”.
    • Integrated loudness: Broadcasts the Integrated loudness measurement value. When this value has exceeded the loudness target, the automation events will be broadcast and written more often. When integrated loudness falls below the loudness target value, the automation events will be broadcast and written less often.
  • Export Loudness CSV: Saves a .csv file with loudness history values captured over the course of the current calculation. The .csv file includes four main pieces of information: Timestamp: h:m:s.ms, Integrated Loudness, Short-term Loudness, Momentary Loudness. The loudness measurements written to the .csv file are only written as absolute loudness values, even if Relative scale is selected in the Loudness meter options. The Integrated loudness trace will not reflect dialogue-gated measurements, even if dialogue gate is selected in the targets control panel in the
    Loudness meter.

    Example of Loudness History CSV Export

    h:m:s.ms, Integrated [LKFS], Short-term [LKFS], Momentary [LKFS],
    00:00:0.5, -16.3116, -33.7392, -13.5834,

    sha1.hpp is a repackaging of the sha1.cpp and sha1.h files from the shallsha1 library (http://code.google.com/p/smallsha1/) into a single header suitable for use as a header only library. This conversion was done by Peter Thorson (webmaster@zaphoyd.com) in 2013. All modifications to the code are redistributed under the same license as the original, which is listed below.
