Sonnox Oxford SuprEsser is a sophisticated dynamic equalizer and de-esser plugin that has become a staple in many professional audio engineers’ toolkits. This versatile tool combines the functionality of a multi-band compressor, a de-esser, and a precision equalizer, offering users unprecedented control over problematic frequencies in their audio material.
SuprEsser plugin utilizes advanced digital signal processing algorithms to identify and attenuate specific frequency ranges dynamically. This allows for precise control over sibilance, resonances, and other unwanted frequency content without affecting the overall tonal balance of the source material. The plugin’s interface is clean and intuitive, featuring a large, resizable spectral display that provides real-time visual feedback of the audio signal and the processing being applied.
Pros:
• Extremely precise frequency selection and dynamic control
• Intuitive interface with excellent visual feedback
• Versatile application beyond just de-essing
• Low CPU usage despite complex processing
• Comprehensive set of controls for fine-tuning
Cons:
• Steep learning curve for beginners
The SuprEsser’s can do both broadband and frequency-specific dynamics processor. You can select a target frequency range with surgical precision, then apply compression or expansion to that range while leaving the rest of the spectrum untouched. This level of control is particularly useful for addressing issues like harsh cymbal overtones, boomy low-end, or overly bright vocals without compromising the overall sound quality. The plugin’s spectral display offers a clear visualization of the incoming audio signal, the selected frequency range, and the amount of processing being applied. This visual representation is invaluable for identifying problem areas and fine-tuning the processing parameters.
Sonnox Oxford SuprEsser sound quality is impeccable, with a transparent and natural-sounding processing that preserves the integrity of the source material. Even when applying significant attenuation, the plugin manages to avoid the artificial or “processed” sound that can plague lesser dynamics processors. This is particularly noticeable when working with vocals, where the SuprEsser can tame harsh sibilants without affecting the overall character of the performance.
In terms of workflow, the SuprEsser offers both simplicity and depth. For quick fixes, users can rely on the auto-level sensing feature and the plugin’s presets to achieve good results quickly. However, for those who want to dive deeper, the extensive set of controls allows for incredibly nuanced adjustments. The ability to solo the detected signal is particularly useful for fine-tuning the frequency selection and threshold settings.
While the SuprEsser excels in many areas, it’s worth noting that its extensive feature set can be overwhelming for beginners. The learning curve is steeper than some simpler de-essing plugins, and it may take some time to fully grasp all of the available parameters and their interactions. However, for those willing to invest the time, the rewards in terms of audio quality and problem-solving capabilities are significant.
In practice, the SuprEsser shines in a variety of scenarios. It’s particularly effective for taming harsh frequencies in vocal recordings, smoothing out resonances in acoustic instruments, and controlling low-end rumble in bass-heavy tracks. Its ability to function as a dynamic EQ also makes it valuable for mastering applications, where subtle, frequency-specific dynamics control can make a significant difference in the overall balance and clarity of a mix.
Compared to similar products like the FabFilter Pro-DS or Waves DeEsser, the Oxford SuprEsser offers a broader range of applications and more precise control. While these competitors excel at de-essing specifically, the SuprEsser’s flexibility allows it to tackle a wider variety of frequency-related issues across different types of audio material.
• Who would benefit most from this product:
• Broadcast audio professionals
• Professional mixing and mastering engineers
• Post-production sound designers
• Music producers working with vocal-heavy genres
• Podcasters and voiceover artists dealing with sibilance issues
Sonnox Oxford SuprEsser is a powerful and versatile dynamics processor that goes far beyond simple de-essing. Its precise frequency control, transparent sound quality, and intuitive interface make it a valuable tool for professional audio engineers and producers. While it may be overkill for casual users, those who require surgical precision in their frequency-specific dynamics processing will find the SuprEsser to be an indispensable addition to their plugin arsenal. Despite a somewhat steep learning curve and a premium price tag, the SuprEsser’s capabilities and sound quality justify its position as a top-tier audio processing tool.
