Sonnox Oxford Inflator is a digital audio processing plugin designed to enhance the perceived loudness and presence of audio signals without introducing unwanted distortion or artifacts. This versatile tool has become a staple in many professional audio engineers’ toolkits, offering a unique approach to increasing the apparent volume and density of tracks, busses, or entire mixes.
Upon first use, the Inflator presents a sleek, minimalist interface that belies its powerful capabilities. The plugin’s GUI features a dark background with clearly labeled controls, making it easy to navigate and adjust parameters quickly. The main controls include Effect, Curve, Input, and Output, each offering precise manipulation of the audio signal. The Inflator’s primary function is to increase the perceived loudness of audio material without pushing it beyond 0 dBFS. It achieves this by using a unique curve-based algorithm that enhances the audio’s harmonic content, creating the illusion of increased volume without actually raising the peak levels. This approach sets it apart from traditional compressors or limiters, as it doesn’t rely on gain reduction or hard clipping to achieve its results.
Pros:
• Increases perceived loudness without introducing harsh distortion
• Preserves transients and dynamic range better than traditional limiters
• Adds warmth and harmonic richness to audio material
• Simple, intuitive interface for quick results
• Low CPU usage, allowing for multiple instances in a project
Cons:
• Can be subtle, requiring careful listening to dial in desired results
• Potential for overuse, leading to fatigue or loss of dynamics if not used judiciously
Oxford Inflator can increase the perceived loudness of audio without significantly altering its peak levels. This is achieved through a proprietary algorithm that manipulates the waveform’s shape, effectively “inflating” the signal without crossing the threshold of overt distortion. The result is a fuller, more present sound that maintains the original character of the source material. When compared to traditional limiters or compressors, the Inflator offers a more transparent approach to loudness enhancement. Unlike aggressive limiting, which can squash transients and introduce audible distortion, the Inflator maintains the punch and clarity of the original signal. This makes it particularly useful for mastering applications where preserving dynamic range is crucial.
The Curve parameter sets Oxford Inflator apart from similar limiter plugins. This control allows users to shape the transfer curve of the process, ranging from a more aggressive, “analog-like” saturation at lower settings to a smoother, more transparent effect at higher values. This flexibility enables the Inflator to adapt to various source materials and creative intentions.
In practical use, the Inflator shines on a wide range of audio material. On drums, it can add punch and sustain without compromising the initial transient impact. Bass instruments benefit from increased presence and harmonic content, helping them cut through dense mixes. Vocals processed through the Inflator gain a subtle lift in perceived volume and clarity, often sitting better in the mix without the need for excessive EQ or compression.
The plugin’s effect on full mixes is particularly noteworthy. When applied judiciously, the Inflator can impart a sense of cohesion and polish to a mix, bringing out subtle details and creating a more impactful overall sound. However, users should exercise caution, as overuse can lead to listener fatigue or a loss of dynamic contrast.
While the Inflator excels in many areas, it’s not a magic bullet for all loudness-related issues. In some cases, particularly with heavily compressed or limited material, the effect may be less pronounced. Additionally, achieving the desired result can require careful adjustment and critical listening, as the changes can be subtle at times.
Compared to similar loudness enhancement tools like the Waves L2 Ultramaximizer or the FabFilter Pro-L 2, the Oxford Inflator takes a distinctly different approach. While those plugins primarily function as limiters, the Inflator’s curve-based algorithm allows it to increase perceived loudness without the same level of peak reduction. This can result in a more open, dynamic sound even when pushing for competitive loudness levels. Inflator plugin also distinguishes itself from saturation plugins like the SoundToys Decapitator or the UAD Studer A800. While these tools can increase perceived loudness through harmonic distortion, the Inflator’s approach is generally more transparent and less colored, making it suitable for a broader range of material.
Who would benefit most from this product:
• Mastering engineers seeking transparent loudness enhancement
• Mix engineers looking to add density and presence to individual tracks or busses
• Electronic music producers aiming to increase the perceived energy of their mixes
• Post-production professionals needing to maximize dialogue clarity and presence
Sonnox Oxford Inflator offers a distinctive approach to loudness enhancement, preserving dynamics while increasing perceived volume and presence. Its transparent operation, versatile Curve control, and low CPU usage make it a valuable tool for various audio applications. While subtle in its effect, requiring careful adjustment, the Inflator excels in adding warmth, clarity, and impact to individual tracks and full mixes alike. Its ability to enhance loudness without introducing harsh artifacts sets it apart from traditional limiters and compressors, making it a go-to plugin for many audio professionals seeking to achieve polished, impactful sound.
