A Handpicked Cache of High-quality Plug-ins
The Sonnox Mastering bundle includes a handpicked cache of their high-quality plug-ins that are guaranteed to add punch and flavor to your 2-bus. Oxford EQ is a classic, and it remains one of the best-sounding equalizer plug-ins in the industry. Oxford Dynamics features a collection of compressors, limiters, gates, and expanders that will make your recordings really pop. Oxford Inflator is one of those “secret weapon” processors that will add power, presence, and warmth to your tracks. Oxford Limiter delivers everything from transparent level control to heavily applied artistic effects. And Fraunhofer Pro-Codec is a must-have tool if you submit your music to online streaming services. The Sonnox Mastering bundle contains the right tools for achieving maximum loudness, density, and presence without sacrificing sound quality.
Note: This product requires that you have an iLok account for authorization, although it does not require a physical iLok key. Please call your Sweetwater Sales Engineer if you have questions.

Oxford EQ
There are a number of reasons why the Oxford EQ plug-in has become the EQ of choice for the quality-conscious audio professional, and many of us at Sweetwater as well. First of all, the Oxford EQ was created by the same team that designed the Sonnox Oxford OXF-R3 console. The Oxford OXF-R3 is considered to be one of the best sounding consoles ever made, which comes as no surprise considering that the designers were the original design team that produced the SSL E series consoles. This team of audio fanatics, whose underlying design philosophy is sound quality first, used the exact algorithms they created for the OXF-R3 console in the Oxford EQ plug-in.
Note: Oxford EQ does not include GML Option (available separately).

Features:
- 5-band parametric design
- Selectable shelf settings on LF and HF sections
- LF and HF filters providing up to 36dB/Octave slope
- 4 selectable EQ types
- Fully de-cramped HF response
- Support for sample rates up to and including 96kHz
- Fully automatable (including separate automation for A and B settings)
- Includes 6 plug-ins in total for optimal DSP usage
- Mono and stereo versions of EQ, filters, and EQ and filters

Oxford Dynamics
The Oxford Dynamics plug-in is based on the same processing used in the famed Sony OXF-R3 console. Originally designed by the same team that designed the SSL E series consoles, the Sony Oxford OXF-R3 console is highly regarded as one of the best sounding consoles ever made. The Sonnox Oxford Dynamics Native plug-in was designed by the same team of sonically obsessed perfectionists. There are three compressor models including linear, normal, and classic styles of compression. The console was a legend in its own time, and Oxford Dynamics brings a legend to your DAW!
Features:
- Channel Dynamics Native with separately controlled sections for Compressor, Limiter, Gate, and Expander
- Channel Dynamics Native includes fully featured 2-band sidechain EQ, which can also be used in signal path
- Separate Bus Compressor/Limiter with surround multi-format support, selectable Sub channel filtering, and gain contribution control
- Selectable linear and exponential time constant curves
- Highly accurate logarithmic sidechain processing
- Fully variable soft ratio function for extreme program tolerance and highly musical compression
- Variable harmonic enhancement for extra loudness, presence, and punch
- Selectable re-dithering function for word length reduction in mastering situations
- Extremely low signal path noise and distortion, below -130dBr
- All functions are fully automated
Oxford Inflator
The Oxford Inflator provides an increase in the apparent loudness of your tracks without obvious loss of quality or reduction of dynamic range. It also avoids damaging increases in the peak level of the signal. Oxford Inflator's processing can also bring power, presence, and warmth to your tracks while providing additional headroom complete with the subtlety and sound of famed tube systems. It's a favorite among mixers for its ability to make just about any source sound more vibrant. Add the Oxford Inflator to your plug-in arsenal and see what you've been missing!

Features:
- Increases the loudness of almost any program material
- Creates warmth, character, and dynamic excitement similar to that of analog systems
- Provides virtual headroom above digital maximum to allow percussive peaks to pass without causing signal overload
- Creates artistic effects ranging from subtle, tube-like harmonic characteristics for warmth, presence, and "in your face" fatness to outright saturation distortion modeling
- Features 2 modes of operation (direct and band split) for maximum flexibility and artistic creativity. These 2 modes also ensure optimal DSP usage

Oxford Limiter
The Oxford Limiter has been developed from decades of professional audio experience to provide a very high degree of quality and facility in program limiting functions. By employing highly accurate logarithmic sidechain processing, along with innovative adaptive timing functionality using look-ahead signal acquisition, the Oxford Limiter provides exemplary performance, whether seeking general transparent level control, program loudness maximization, or heavily applied artistic sound effects. It also provides additional processing in the form of its unique Enhance function, which allows unprecedented volume and punch to be applied to your program beyond that available from conventional limiting functions, without incurring the risk of producing either peak sample overloads or reconstructed errors in end-user equipment.
Features:
- Unique Enhance section — provides sample value limiting and enhances perceived loudness
- Ability to add harmonic distortion, where artistic style requires
- Variable soft knee control
- Attack and Release controls
- Reconstruction Meter shows 'actual' signal rather than sampled signal
- Auto compensate feature — corrects recon errors without losing overall program loudness
- 16- and 24-bit dithering with 5 selectable types
- User has control over variable depth noise shaping
- 16 presets — some quite extreme!
Fraunhofer Pro-Codec
When you're optimizing MP3 mixes for use online, you need the right tools for the job. Sonnox's Fraunhofer Pro-Codec plug-in makes it incredibly easy to audition encoded or decoded material — in real time. Plus, you can audition up to five codecs at the same time. The Fraunhofer Pro-Codec's intuitive display shows the input signal, the output difference signal, and a visual representation of how much codec-induced noise can be heard. You'll also appreciate the A-B auditioning and blind listening modes, which give you even more flexible auditioning options. The Fraunhofer Pro-Codec plug-in can even batch encode to multiple formats at the same time!

Features:
- Allows auditioning of up to 5 codecs in real time
- MP3, MP3 Surround, MP3 HD, HD-AAC, AAC-LC, and HE-AAC codecs supported
- Intuitive display
- Bit-stream integrity meters for detecting potential decode overloads
- Instant A-B auditioning
- Blind listening mode
