The Universal Audio Precision Limiter is a single-band, look-ahead brick-wall limiter made primarily for use with program material. The very easy to use Precision Limiter achieves 100% attack within a 1.5ms look-ahead window, which prevents clipping and guarantees zero overshoot performance. Both the attack and release curves are optimized for professional mastering, which minimizes aliasing.

The Precision Limiter is a colorless, transparent mastering limiter-no upsampling is used, nor does the Precision Limiter pass audio through any filters - audio remains untouched unless the compressor is working, in which case, only gain is affected.
The Precision Limiter also features comprehensive, high-resolution metering and conforms to Bob Katz's "K-system" metering specs. This metering allows the user to see what is happening to audio with a great deal of accuracy, with simultaneous RMS and Peak metering and adjustable Peak Hold; the plug-in can also be bypassed and used strictly as a high-resolution meter.

Other features include options for a user-adjustable Release or intelligent Auto Release, which allows for fast recovery--minimizing distortion and pumping. The unique Contour Mode switch offers two different methods to tailor the attack shape and can affect overall "presentation" or perception of how "up front" a track feels. Switching the Contour Mode can be useful on minimal and/or acoustic program material, yielding a more subtle touch.
