Dynamics Meters


Ozone provides three types of meters for viewing the dynamics of a mix. You can set options for these meters by right clicking on any of the dynamics meters, or selecting the Dynamics Options or the Maximizer Options in the Options panel.

 

Threshold Control Meters

Both the Dynamics and Maximizer modules feature Threshold Control Meters that allow you to adjust the thresholds of the gate, compressor, and limiter in the Dynamics module and the threshold and the margin of the Maximizer, while monitoring how the signal is being affected in real time.

The Threshold Control can display gain reduction as it is taking place with level meters.  To enable the Gain Reduction level meters, right- (or control-) click on the threshold control’s meter window and choose the Gain Reduction option.   Two meters display the levels of the incoming signal and as gain reduction begins to take place, a gain reduction meter appears in red between the two level bars.  The Threshold meter also displays the amount of gain reduction in real-time with a dB readout at the bottom.  

The Threshold Control can also display a Histogram, a history of level over time. To enable the histogram, right- (or control-) click on the threshold control’s meter window and choose the Histogram option. This allows you visualize the overall "level content" of the audio by providing a running display of the history of levels in the audio.

 

Reduction Meters

When working in the multiband dynamics and loudness maximizer modules, the reduction meter provides you with a readout of how much the dynamics processing is changing the level of the signal. You can set this to display the amount of compression and limiting, and/or the amount of gating by right-clicking (under OS X you can also ctrl-click) on the meter.

In the screen above, on the left the compressor at that point in time is compressing or reducing the level of the input signal by 1.9 dB and on the right the Maximizer at that point in time is limiting or reducing the level of the input signal by 1.5 dB.

 

Level Histograms

Level histograms can be turned on in the Dynamics and Maximizer modules to provide a view of the audio level as a function of time in the Threshold Controls.

 

Dynamics Histogram    Maximizer Histogram

 

As Ozone processes audio, it calculates the level and displays it on the level histogram. Unlike a standard level meter, the level histogram provides a view of the history of the level over time. The height of the histogram represents the high and low levels of the audio, while the width of the bar indicates the most frequent levels.

For additional visual feedback, an additional histogram is displayed for regions that are being limited by the Loudness Maximizer or the Multiband Dynamics.

Dynamics Histograms

Dynamic Curve Meter

This meter shows the input signal (x axis) plotted against the output (processed) signal (y axis). More horizontal compression curves means the signal is being flattened (compressed) more.

By default, the range of the meter is from 0 dB to -64 dB. You can adjust the range by pressing the (+) or (-) buttons in the graph to see a zoomed-in or zoomed-out view of the curve.

Dynamic Curve Meter

Note: If you zoom out completely so the range is 0 dB to -128 dB, you'll be able to set compressor/limiter/expander thresholds down to -130 dB. When you zoom in again, the thresholds will keep their values, even though the sliders will adjust to allow finer control of thresholds between 0 dB and -80 dB.

You can also set individual options for this meter by right-clicking (under OS X you can also ctrl-click) on it to bring up the dynamics meter options screen.

Nodes:

The meter features individual nodes for the limiter, compressor, and expander as well as nodes surrounding these that represent input and output. These nodes are linked to the Threshold and Ratio controls, and can be used to adjust the curve in a visual way, rather than setting them with the standard controls.

Advanced Nodes

 Advanced Nodes:

You may variably adjust the knee of each stage of the dynamics process from hard to soft with horizontal handles that appear when a node is selected.  (Ozone 5 Advanced)
