Oxford Limiter


Transparent and precise look-ahead true peak limiting.

The True Peak Limiter Plugin for Mastering

Using conventional audio limiters can result in a loss of dynamic range and transient power, meaning that your mix loses impact and emotional resonance with the listener.

Every mastering engineer’s worst nightmare is having the final master sounding overly squashed, with key transient components such as the kick and snare having lost all of their weight and bite.

The Oxford Limiter has been designed to combat this problem, enabling limiting that allows loud mixes to maintain their punch and clarity.
