Oxford Dynamics - HDX is an AAX dynamics processing plugin from Sonnox that combines a gate, expander, compressor, limiter and two-band side-chain EQ in one mastering-oriented effect.
Oxford Dynamics - HDX bundles six independent dynamics processes into a single plugin. Producers can use it for subtle control of a vocal or for a pumping side-chained effect, and the gate and expander handle fast gating and precise expansion. A warmth control adds optional tube-like harmonic saturation when a track needs extra presence. The plugin is built for Avid HDX systems, where its processing runs on the DSP rather than the host CPU.
The plugin offers three compressor types: Normal, Classic and Linear. The knee is variable, with settings from 0 dBr to -20 dBr in 5 dB steps, so the compression curve can be shaped from hard to soft.
The warmth control adds tube-like saturation for extra presence. Sonnox describes the processing as ultra-low in noise and distortion, and the dynamics section is taken from the Sony OXF-R3 console.
Oxford Dynamics - HDX covers both track-level and bus-level work. A two-band side-chain EQ lets the detection signal be filtered before it drives the compressor or gate, which is useful for pumping effects and frequency-selective control.
A surround bus compressor and limiter is included, available on HDX only.

Oxford Dynamics - HDX is available in AAX format only.
The plugin runs on Windows 10 or later and on macOS 10.12 or later, including M1 Macs through Rosetta 2.
It requires Pro Tools 11 or later with AAX Native and AAX DSP support, plus an iLok USB 2 or 3 key with the latest drivers or an iLok Cloud authorisation with an active internet connection. It is intended for Avid HDX systems; without one, Sonnox recommends the native version.
Sonnox states there is no difference in sound quality between the Standard and HDX versions. The HDX version moves processing to the Avid DSPs to reduce load on the host processor.
