1. Mode 2. Threshold 3. Character 4. Stereo Independence 5. Transient Emphasis
Mode
The Maximizer includes the following Intelligent Release Control (IRC) modes:
1. IRC LL: Provides the intelligent digital loudness maximization of IRC I with lower latency. IRC LL is the lowest latency and least CPU intensive IRC mode.
2. IRC I: Provides intelligent digital loudness maximization of the signal. It does this by analyzing the source material and applying limiting in a psychoacoustically pleasing manner, reacting quickly to transients (to prevent pumping) and reacting more slowly to steady bass tones (to prevent distortion).
3. IRC II: Similar to IRC I, but optimized to preserve transients even more, so they sound sharper and clearer in the output signal, even when aggressive limiting is taking place.
4. IRC III: Allows for the most aggressive limiting by using an advanced psychoacoustic model to intelligently determine the speed of limiting that can be applied to the incoming signal, before producing distortion that is detectable to the human ear. Very CPU-intensive, and produces high latency, especially at higher sampling rates. You may nd that at sampling rates greater than 48kHz you are unable to use IRC III mode in real-time.
1. IRC III Character Styles: The following character styles will help you manage the limiter’s sound by constraining its

release behavior:
1. Clipping: The most aggressive style setting of IRC III and will slightly colorize your mix with distortion or achieve the highest degree of loudness with the greatest risk of clipping.
2. Crisp: Agressively constrains the limiter’s release behavior and will favor distortion over any pumping.
3. Balanced: Constrains the release behavior of the limiter in a generally transparent way and should be suitable for most material.
4. Pumping: The least aggressive style setting for IRC III and does not constrain the limiter’s release behavior. It can tend toward a slower release behavior and may result in pumping. This is the “legacy” setting and is the behavior used in Ozone version 5.01 and earlier.
5. IRC IV: This mode builds upon our existing IRC technology by shaping the spectrum to further reduce pumping and distortion. As the signal goes farther over the threshold, the IRC IV algorithm limits frequency bands that contribute most to these peaks. This reduces intermodulation between different signal components and uses dozens of psychoacoustically spaced bands in order to react to any type of audio. When no limiting is necessary, the spectrum will be unaltered. Most CPU-intensive, and produces high latency, especially at higher sampling rates.
1. IRC IV Character Styles: The following character styles will help you manage the limiter’s sound by constraining its release behavior:
1. Classic: Provides general enhancement of the overall mix with a sound more reminiscent of Ozone’s earlier limiting algorithms which are still being used by professionals today.
2. Modern: Provides general enhancement and life to your mix but with greater detail and clarity than the Classic style.
3. Transient: Optimized for maximum preservation of all transients resulting in a highly detailed overall sound that may bene t some mixes needing added clarity.

Threshold
Adjust the threshold of the Maximizer to set the level at which the limiting processing takes place and determines the amount of gain added to maximize the output level.
THRESHOLD AND MAXIMIZER OUTPUT Setting the Threshold to a non-zero value that doesn’t trigger the limiter will still increase the output of the Maximizer. For example if the input level to the Maximizer is peaking at -15 dB and the Maximizer Threshold is set to -4dB, limiting will not occur, but the level at the output of the Maximizer will be peaking at -11dB.
The threshold control includes the following sub-controls and meter:
1. Threshold Meter 2. Ceiling 3. Link 4. True Peak

1. The two outer meters display input level to the limiter. 2. The two inner meters display gain reduction applied by the limiter. 3. The text readout at the bottom of the meter displays the current
gain reduction amount that is being applied by the limiter.
Ceiling
Adjust to set the maximum output level of the Maximizer.
CEILING, DITHER, AND CODEC PREVIEW It is generally recommended to use a setting of -0.3 dB when dithering, or a more dramatic setting (-0.6 dB to -0.8 dB) when mastering audio to be converted to .mp3 or .aac later, in order to prevent clipping in the future. See the Codec Preview section for more details.
Threshold and Ceiling Link
Enable to link the Threshold and Ceiling controls. Adjusting either control in linked mode will adjust the other control by the same amount and vice versa.

True Peak
When enabled, the limiter will account for the levels of each digital sample and the levels of the analog signal that will eventually be produced by D/A conversion. This is sometimes necessary, since an analog signal’s peak level can exceed the corresponding digital signal’s peak level by more than 3 dB.
TRUE PEAK LIMITING & CPU USAGE
This option will result in a small increase in CPU usage, but if your mixes are running very hot you may want to enable it to ensure that absolutely no distortion is introduced when your audio is nally run through a D/A converter.
Character
Adjust to customize the overall response time (attack and release times) of the maximizer processing. The attack and release times used are dependent on the selected Mode, and allows a continuous range from Fast (0.0) to Slow (10.0) in each mode.
Stereo Independence
The Stereo Independence controls represent the next iteration of the Stereo Unlink control in previous versions of Ozone. By default, the Stereo Independence controls (Transient and Sustain) will be linked and set to 0% – mimicking the default settings of the previous Stereo Unlink control.
1. Transient Slider: Adjusts how the limiter responds to transient material across channels.
2. Sustain Slider: Adjusts how the limiter responds to sustained material across channels.
3. Link: Links the Transient and Sustain sliders.

EXAMPLES
1. Both Sliders set to 100%: It is possible to achieve a louder output from the Maximizer, but this can result in a narrow stereo image. To alleviate the narrowing effect of the Stereo Unlink control, we split this feature into two sliders.
2. Sliders independently set to non-zero values: Applies limiting to transient and sustained material separately, based on a level envelope generated from a ratio of the individual channel levels and the entire stereo image.
Transient Emphasis
Enable Transient Emphasis adjustment by clicking the Transient Emphasis power button. Adjusting the Amount control allows you to
ne-tune the shaping of transients before limiting takes place. This can be useful for preserving sharper sounds, like drums, while still optimizing loudness.
TRANSIENT EMPHASIS SETTINGS Using higher amount values for Transient Emphasis will result in more pronounced transients after the limiting process.
Ozone Application

AAC & MP3 CODECS USED BY OZONE For AAC, Ozone uses Fraunhofer’s codec. For MP3 the LAME codec is used (www.mp3dev.org). If an MP3 or AAC format is selected,
les are exported with a 44.1kHz sampling rate.
SAVE PATH OPTIONS
1. If the project is unsaved, the default save path is your Documents folder.
2. If the project has already been saved, the default save path is an Exported Audio Files folder in the same location as the project.
Enable Dither
Allows you to preserve the sound quality and dynamic range of a higher bit depth, when exporting the audio le to a lower bit depth. Ozone processes les at 32-bit so dither is desirable for les being exported to values lower than 32-bit.
1. For example, a common work ow is to record audio at 24-bit resolution, then import and process the audio in an application such as Ozone, which will process at a higher resolution (32-bit).
2. If you are releasing the audio material on a commercial CD, it must be converted to 16-bit audio, the required bit depth of the “Red Book” CD audio format.

Overview
Master Assistant is designed to provide an intelligently tailored starting point for your track, to help you create a professional-sounding master, regardless of your experience level.
Master Assistant utilizes target genre curves that were born from a mixture of internal discussion and research. We started by grouping a large variety of audio les into ten classes of musical genre. These genre classes were then analyzed for their spectral characteristics. Based on our research, we created a number of target curves that represent the typical spectral characteristics for each genre class. Master Assistant analyzes your track to determine how similar it is to the different genre curves. Each genre curve is assigned a percentage of similarity and the percentages are used to create a unique target curve for your track.

always enable band 1 (Low Shelf) and band 8 (High Shelf). Up to six Peak Bell lters may be enabled on bands 2-7. 2. DYNAMICS: Uses crest factor measurement of the input to determine if Dynamics processing will positively affect the output of the Maximizer. Sets Threshold values by learning the average input level.
NOTES ABOUT CREST FACTOR MEASUREMENT
1. Applying light low-end compression to overly dynamic audio allows the Maximizer to operate more transparently. In many cases, crest factor is calculated based on the low frequency band of the input signal. If your track is assigned a high percentage of similarity to the broad “Orchestral” category, crest factor calculation will be based on the full bandwidth of the input signal.
2. The Dynamics module will only be enabled by Master Assistant if the crest factor is higher than a predetermined cutoff value.
3. The full crest factor range used by Master Assistant is -1 to 14. The “ideal” crest factor range is 3 to 10.
4. When the crest factor is lower than 3, a track might be considered “too compressed.” When the crest factor measurement is higher than 10, a track might be considered “too dynamic.”
3. MAXIMIZER: Sets Ceiling and Threshold based on the target loudness value and destination settings. Compares the input and output signals of the Maximizer to determine which frequencies are hitting the limiter the hardest.
4. DYNAMIC EQ: Sets Dynamic EQ bands to peak frequencies found when comparing the Maximizer input and output signals in order to reduce potential distortion when limiting. Learns and sets Threshold controls based on the input level to the bands.

Vintage
In this mode, a mixture of non-vintage and vintage modules will be included in the signal chain generated by Master Assistant.

The following section details how each of the modules included in the Vintage mode chain are affected by Master Assistant.
1. EQUALIZER: Compares the input audio to the unique target curve generated by Master Assistant. Band settings are adjusted to match your track to the unique target curve. Master Assistant will always enable band 1 (Low Shelf) and band 8 (High Shelf). Up to six Peak Bell lters may be enabled on bands 2-7.
2. VINTAGE EQ: Adjusts low boost and high cut controls to add warmth and tonal character to your track.
3. VINTAGE COMPRESSOR: Analyzes the dynamic range of the input audio. If extreme dynamic range is not detected, the Vintage Compressor will be bypassed but still included in the signal chain.
4. VINTAGE LIMITER: Makes linked adjustments to the Threshold and Ceiling controls to add an analog character to the signal without introducing level differences.
5. MAXIMIZER: Sets Ceiling and Threshold based on the target loudness value and destination settings.
Loudness & EQ

Level Detection Mode
Determines how the input signal level is measured by the Dynamics level detection circuit. This is a global setting, shared by all bands in multiband mode.
1. Peak: Uses the peak level of the incoming signal. In general, this setting is useful when you are trying to even out sudden peaks in your music.
2. Env: (Envelope) Uses the average level of the incoming signal evened out across the frequency spectrum. Similar to RMS mode but with some advantages. Unlike RMS, Envelope mode produces

even levels across all frequencies and will not produce the aliasing or artifacts that RMS detection can cause. 3. RMS: Uses the average level of the incoming signal. RMS detection is useful when you are trying to increase overall level without changing the character of the sound.
Threshold
Determines the signal level at which the compressor or limiter begins processing. The handle on the left controls the Limiter Threshold, the handle on the right controls the Compressor Threshold.

Threshold Input Meter
Displays the input level to the level detection circuit (outer meters, displayed in grey) alongside the gain change applied as a result of the dynamics processing (inner meters, displayed in the corresponding band color).

Gain reduction is drawn from the top to the bottom of the meter, gain increase is drawn from the bottom to the top of the meter.
Ratio
Determines the amount of gain reduction applied to a signal when the threshold is crossed.
Compressor Ratios
1. Compressor Ratio Default: 2:1. 2. Compressor Ratio Range: (10):1 to 30:1. Note: (10):1 is shown as
0.1:1 in All Bands View. 3. Positive Compressor ratios result in downward compression.
Downward compression reduces the level of signals that reach the threshold and leaves signals below the threshold unaffected. 4. Negative Compressor ratios result in upward compression. Upward compression raises the level of signals that fall below the threshold and leaves signals above the threshold unaffected. Upward compression can gently raise levels instead of pushing down peaks.

Limiter Ratios
1. Limiter Ratio Default: 10:1. 2. Limiter Ratio Range: (2.5):1 to 30:1. Note: (2.5):1 is shown as
0.4:1 in All Bands View. 3. Positive Limiter ratios result in downward compression (limiting).
Higher ratios, particularly 10:1 or greater, result in limiting (more extreme downward compression).
LIMITER BEHAVIOR AT MAXIMUM RATIO SETTING
The Limiter in the Dynamics module is similar to the response of a limiter in the analog domain. When the Dynamics Limiter Ratio is set to 30:1, some overshoot may still occur because it does not function as a Brickwall limiter.
4. Negative Limiter ratios result in upward expansion. Upward expansion raises the level of signals that exceed the threshold. Upward expansion can be used to add punch to dull mixes or emphasize the beat in rhythm-heavy music.
Attack
Determines the amount of time, or how quickly it takes (in milliseconds), for the dynamics to react and for the signal to become fully compressed after exceeding the threshold level.
Release
Adjusts the amount of time (milliseconds) it takes for the dynamics processor to return to unity gain (recovers gain) when the input signal falls below the threshold.

Knee
Adjusts a range around the threshold that determines how abruptly processing is applied to a signal as it approaches the threshold.
1. Higher values create a “soft knee” effect, which gradually introduces processing as the signal approaches the Threshold level. This provides subtler, more natural sounding compression.
2. Lower values create a “hard knee” effect, which abruptly begins processing when the signal crosses the Threshold level. This offers more aggressive sounding compression and is often used on individual tracks, such as kick or snare drum.
Parallel
Adjusts the amount of the “dry” (unprocessed) signal to mix with the “wet” (processed) signal. This technique is also known as “parallel compression”. This control is available for each band individually.
Dynamics Curve Meter
The Dynamics Curve Meter is an interactive plot of the Threshold, Ratio, and Knee controls as they relate to input and output levels. The y-axis represents output level (dB) and the x-axis represents input level (dB). You can zoom in/out by clicking the +/- buttons that appear in the bottom right when hovering your cursor over the meter. Signal activity is drawn below the curve in the associated band color.

Use the arrow buttons to the left and right of the Band # button to switch between available band views.
Link Bands
When enabled, all band speci c control adjustments will be linked relative to their current settings.
Global and Band Gain
Adjusts gain after Dynamics processing, useful for compensating for level differences caused by Dynamics processing. You can make adjustments to Global Gain and Band Gain simultaneously.
1. Band Gain: Adjusts the amount of gain applied to the associated band after Dynamics processing. When working in the Selected Band View, the Gain slider for the currently selected band is located on right side of the Dynamics module controls panel. When working in All Bands View, a Gain control is located directly below the threshold meter for each band.
2. Global Gain: Adjusts the amount of gain applied to the output signal of all bands after Dynamics processing. The Global Gain control is located on the right side of the Dynamics module controls panel when All Bands View is selected. The Global Gain slider is hidden when you are working in the Selected Band View.
Auto Gain
When enabled, make-up gain is automatically calculated and applied to the output signal to compensate for level differences introduced by dynamics processing. The automatic gain control calculates the RMS levels of the input and output signals independently for each Dynamics crossover band. Gain is automatically applied to the output signal based on the RMS level difference between the input and output signals. Auto gain and manual global/per-band gain adjustments can be applied simultaneously.

Adaptive Release
When enabled, automatically adjusts the Release time of the Compressor based on the peak factor of a signal.
1. If a transient signal is detected, the Release time is scaled to be shorter to reduce pumping.
2. If a sustained signal is detected, the Release time is scaled to be longer to reduce distortion.
AUTO RELEASE ADJUSTMENTS The Release time is scaled in relation to the Release value set by the user. For example: if you are using the Compressor with the Release time set to 100 ms, the Release time will be automatically adjusted to a value within a range of 20 ms to 200 ms, depending on the type of signal that is being processed.

Width
Adjusts the amount of gain applied to side channel content. Positive values will increase perceived stereo width, and negative values will decrease the perceived stereo width of a band. A setting of -100 will make the output of the associated band effectively mono.
NOTE If the input signal to the Imager is either: mono (i.e. single channel) or effectively mono (i.e. a stereo le with the same content on both channels), you will need to enable the Stereoize feature for Width adjustments to have an effect on the signal.

Stereoize
Stereoize processing is applied to all processing bands equally. The following controls allow you to enable the effect and adjust the associated settings.
1. Stereoize power button: Enables/disables stereoize processing. 2. Stereoize Amount: Adjust the slider to add natural-sounding
stereo width to narrow recordings and to control the character of the stereo effect in conjunction with the width sliders.
STEREOIZE IS MONO COMPATIBLE The Stereoize effect is completely mono compatible. Even if you add width to audio, it can still be played back in mono without producing unpleasant artifacts.
3. Stereoize Modes: There are two different stereoize processing modes available in the Imager:
1. Mode I: Haas Effect-based decorrelation processing. This mode creates a delayed copy of the mid channel signal and injects it into the side channel.
2. Mode II: A newly developed alternative to the classic stereoize mode. This new mode has a slightly different tonal quality from the original and helps to preserve transients at higher settings.
Vectorscope
The vectorscope meters provide a view of the stereo image of the signal after all other processing is applied, regardless of the Imager’s position in the signal chain.
Polar Sample
Plots dots per sample on a polar coordinate display to highlight the stereo image of the incoming signal.

Patterns that appear within the 45-degree safe lines represent in-phase audio. Patterns outside these lines represent out-of-phase audio. The history of the Polar Sample Vectorscope fades out slowly. You can reset the display by clicking on the meter.
Polar Level
Plots rays on a polar coordinate display that represent sample averages and displays the stereo energy of a recording.

The length of the rays represents amplitude. The angle of the rays represents their position in the stereo image. Rays within the 45-degree

safe lines represent in-phase audio. Rays beyond the safe lines represents out-of-phase audio.
Lissajous
Plots per-sample dots on a traditional oscilloscope display similar to the Polar Sample vectorscope.

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). Horizontal patterns mean the two channels are very different, which could result in mono compatibility problems.

Correlation Meter Bar
The vertical bar meter to the right of the vectorscope indicates the degree of similarity (or correlation) between the left and right channels.
TIPS
1. If the left and right channels are exactly the same, the correlation value would be +1 and the meter tick would be drawn at the top.
2. If the left and right channels are exactly out-of-phase the correlation would be -1 and the meter tick would be drawn all the way at the bottom.
3. In general, most recordings have phase correlations in the 0 to +1 range. A brief readout towards the bottom half of the meter is not necessarily a problem but could represent a possible mono compatibility issue.
4. As you increase stereo widening, the phase correlation will tend to draw more towards the bottom half of the meter, as the left and right channels will become “wider” and less similar.
Stereo Balance Meter
The horizontal bar meter directly below the vectorscope meter indicates the stereo balance of the signal. When the meter tick is drawn all the way to the left, it indicates there is only information on the left channel. When the meter tick is drawn all the way to the right, it indicates that there is only information on the right channel.

Fine Tune
The Fine Tune controls can be used to adjust the shape and intensity of the matched curve.
1. Smoothing: Determines the amount of precision to apply to the matched curve. Higher smoothing is less precise. Lower smoothing is more precise.
2. Amount: Determines the amount of processing (intensity) to use when matching the Reference curve to the Apply To curve.
RECOMMENDATIONS
1. A Matched Curve amount of 100% and a Smoothing amount of 0% might be technically the closest match to your “Reference” mix, but in reality it’s probably not the most effective combination of the settings. Those settings will try to capture every peak, valley, and level, which can result in extreme, unnatural EQs.
2. We suggest working with the Matched Curve amount under 50%. If your Matching EQ curve has narrow peaks and valleys, increase the Smoothing parameter to smooth them out. Your goal is to capture the overall tonal shape of the Reference as opposed to an exact match.

SPECTRAL SHAPER THRESHOLD INPUT METER The threshold input meter in the Spectral Shaper displays different information than it does in the Maximizer or Vintage Limiter module. In the Maximizer and Vintage Limiter, the threshold input level is based on the full frequency spectrum of the input signal. The Spectral Shaper threshold input level is based on the highest level of the frequency bands included within the action region.
Listen
Toggles isolated playback of the signal that is reduced as a result of Spectral Shaper processing. This signal is the difference between the input and output signals.
Tone
Adjusts the spectral tilt of the Spectral Shaper processing. Positive values tilt towards a brighter overall spectral character, negative values tilt towards a darker overall spectral character.
Attack
Set the amount of time it takes for the Spectral Shaper to apply gain reduction to signals that exceed the Threshold.
Release
Set the amount of time it takes for the Spectral Shaper to stop applying gain reduction to signals that fall below the Threshold.

Overview
The Vintage Compressor is an emulation of a feedback compressor with a detection lter in the feedback loop. The Vintage Compressor includes a versatile detection lter in the feedback loop that lters the signal passed into the level detector to change which components of the signal are triggering the compressor. Some compressors use a highpass lter or a high shelf boost to reduce pumping. Others have a wide boost in the high frequencies to let high frequency content drive the compressor. The Vintage Compressor in Ozone includes all of these
lters. We combined some of the best elements of vintage analog compressors to create this feedback compressor algorithm.
The Vintage Compressor module interface is divided into the following sections:

Threshold
Adjust the threshold to set the point where the dynamics processing takes place. Since some modes have a soft knee, mild compression may occur below this point.
Threshold Meter
Displays the input level to the module alongside the gain reduction applied by the module’s processing.

1. The two meters on the far left and right of the threshold meter display the input audio level.
2. The two meters in between the input meters display the gain reduction applied.
Ratio
Sets the amount of attenuation applied to the signal once it has passed the threshold. Higher ratios will result in more compression.

Attack and Release
Adjust the attack and release controls to set how quickly the Vintage Compressor reacts to audio that crosses the threshold.
1. Attack: Determines how quickly the Vintage Compressor reacts when the threshold is reached.
2. Release: Determines the amount of time before the Vintage Compressor returns the level to normal once the signal is no longer above the threshold. This control sets the release time for transients; for sustained compression, the release time will be signi cantly longer.
Gain
Adjusts the output gain of the Vintage Compressor module to makeup for decreases in volume.
Auto Gain
When enabled, Auto Gain calculates the RMS levels of both the input and output signals of the Vintage Compressor in order to apply the appropriate gain to the output signal.
Auto Gain acts as a smart “make-up gain” control that adapts over time and adjusts your levels to a comparable level of your unprocessed audio.

Pultec EQP-1A Controls
The top row of controls includes lters modeled after the Pultec EQP1A.
A unique feature of the Pultec EQP-1A is the ability to simultaneously adjust the boost and cut parameters for the low frequency band. While the original manual warns “Do not attempt to boost and attenuate simultaneously,” these controls interact in a way that many engineers have found to be desirable. Rather than canceling each other out, combining these controls results in a boost in the low frequencies, followed by a dip at slightly higher frequencies. This unique shape is also available in the Ozone Equalizer module with the “Vintage Low Shelf” lter shape.
Low Boost/Cut Controls
1. Low Frequency (Hz): Sets the frequency of the low shelf lter. Options include: 20 Hz, 30 Hz, 45 Hz, 60 Hz, and 100 Hz.
