Tonal Balance Control

Overview

Tonal Balance Control displays spectrum metering information for the track it is currently inserted on relative to a target curve. This is particularly useful when dealing with tonal balance issues that arise during mixing and mastering. Tonal Balance Control can help provide context and direction toward resolving issues with a mix or master lacking the low-end power or high-end brilliance found in professionally produced, radio-ready material..

Tonal Balance Control should live at the end of your processing chain

  • To get the most out of the Tonal Balance Control plug-in, we recommend that it is inserted at the end of the processing chain on your master bus track.
  • This ensures that the spectrum curve you are comparing to the currently selected target curve is after all other processing in your session.
  • When Tonal Balance Control is last in the processing chain, it ensures that adjustments made to Neutron 2 or Ozone 8 EQ instances will affect the spectrum curve displayed in Tonal Balance Control.

The factory target curves in Tonal Balance Control represent typical spectral shapes found in different styles of music. These target curves were created by analyzing the spectral characteristics of numerous tracks across different genres/styles of music. The target curves display ranges of typical spectral variation across the frequency spectrum for these similar styles of music.

Meters

Broad View

Broad View

Broad View displays target curve ranges split into four frequency bands.

  • Low: 20 Hz - 250 Hz
  • Low-mid: 250 Hz - 2 kHz
  • Mid: 2kHz - 8 kHz
  • High-mid: 8 kHz - 20 kHz

The blue bars shown in each frequency band represent the typical range of spectral variation for the selected target curve.

The white lines will update to show how your track compares to the target curve. You can make adjustments to Ozone and Neutron EQ instances to modify your mix to fall within the blue target ranges.

Fine View

Fine View

Displays the selected target curve range in blue across the frequency spectrum. The white spectrum curve in this view represents your current track.

Band Indicators

Band Indicators

The frequency band labels will turn white when your current track is within the typical range for the selected target curve.

Crest Factor

Crest Factor

The Crest Factor meter shows information about the low end dynamic range of your track. When the meter is weighted to the left, it indicates that your mix is ‘too dynamic’ in the low end. When weighted to the right, it indicates that your mix is ‘too compressed’ in the low end.

Target Curves

Target Menu

Tonal Balance Control comes with 3 factory target curves that represent the typical spectral curves found in major musical styles.

  • Orchestral
  • Bass Heavy
  • Modern

When checked, anonymous usage data will be sent to help iZotope improve future products.

Enable Tooltips

When checked, tooltips with information about a control will appear when hovering the cursor over most controls in the Tonal Balance Control interface.

Spectrum

Average Time

Averages the spectrum 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.

Frequency Scale

Sets the frequency scale used by the Tonal Balance Control meter. Choices include:

  • FLAT LOG
  • EXTENDED LOG
  • PIANO ROLL

Note

You can access and change the frequency scale option without opening the options window by right-clicking on the frequency ruler in the Tonal Balance Control interface.

Ozone & Tonal Balance Control

Select Ozone 8 instances from the plug-in selection menu in Tonal Balance Control to modify EQ parameters remotely or view the spectrum metering of any Ozone 8 plug-in.

Ozone 8 instance selected

The following table outlines the controls and displays available when the associated Ozone 8 plug-in is selected as the incoming instance in Tonal Balance Control.

Plug-in/Module Name EQ Controls? Spectrum Display?

Global EQ Controls

global control bar

  • PLUG-IN SELECTION MENU: Allows you to select the instance to display/control from within the Tonal Balance Control interface.
  • ANALOG/DIGITAL/SURGICAL EQ MODE:
  • BYPASS: Momentarily bypasses EQ processing in the selected Ozone 8 plug-in. This bypass control is useful for quick A/B comparisons.
  • SHOW/HIDE SELECTED PLUG-IN DISPLAY: Toggles the incoming instance display panel open or closed.

Note about EQ Bypass state

  • If the selected EQ is bypassed in the plug-in, the controls will appear dimmed in Tonal Balance Control. To enable the EQ in the selected plug-in, you will need to open the plug-in window and unbypass the EQ. EQ bypass state of a selected plug-in can’t be changed from the Tonal Balance Control interface.

Metering & Navigation

Spectrum and EQ curve

  • SPECTRUM METERING: Displays spectrum metering for the selected instance. Ozone 8 plug-ins will display their spectrum metering in orange.
  • EQ CURVE: If the selected Ozone 8 instance supports EQ control, the EQ curve controls will show in the spectrum meter area.

Tips for working with EQ nodes

  • Change Filter Shapes: You can change filter shapes of any visible node by right-clicking on the node and selecting the filter shape from the context menu that appears.
  • Reset node to default: Double-click on a node to reset it to default values.
  • Enable bands with double-click: Double-click in an empty spot in the spectrum display to enable a band at that frequency/gain.

BAND SELECTION & ENABLE/DISABLE CONTROLS: Band select and enable bar * EQ bands can be enabled or disabled by clicking on the power button to the left of the band number. * Click on the band number directly to view the controls associated with that band.

EQ Controls

EQ controls for the currently selected Ozone EQ are located in the bottom bar of the Tonal Balance Control interface.

EQ Controls

  • FREQUENCY: Sets the center frequency for the selected filter.
  • GAIN: Sets the positive/negative gain applied to the selected filter.
  • Q: Sets the bandwidth of current filter.
  • PHASE (Digital/Surigical Mode Only): Controls the mixed phase response of the current band. 0% = Linear phase response; 100% = minimum phase response.

General Notes

Control Availability

The following controls are accessible in the Ozone 8 EQ/Post EQ modules and EQ component plug-in, but cannot be accessed from the Tonal Balance Control interface:

  • EQ module/plug-in Bypass
  • Matching EQ controls
