Pro Limiter

Pro Limiter


Developed from the ground up, the Avid Pro Limiter lets you maximize the loudness of your mix—in up to 7.1 surround—without distortion or harshness. Designed to be completely transparent sounding, the plug-in prevents audio from clipping and pushes the volume of your mix further, while preserving the sonic quality and underlying dynamics of the performances.


Pro Limiter offers a variety of features that go beyond capabilities found in most other limiter products, providing detailed and nuanced control of the audio signal loudness:

  • Clean and transparent sound—Sits well in the mix while maintaining tight control over output levels
  • Unique Character knob—Add soft saturation to get more loudness and a higher amount of gain reduction, without the unwanted digital artifacts of standard brick wall limiters
  • True Peak limiting — Pro Limiter limits incoming audio to the True Peak of the signal, to prevent inter-sample peaks that could introduce distortion during encoding or analog conversion
  • BS.1770-3 loudness metering — Pro Limiter complies with the ITU-R BS.1770-3 loudness metering standard, including True Peak, Integrated Loudness, and Loudness Range measurements, and is suitable for both EBU R128 and ATSC A/85 (CALM Act) broadcast workflows
  • Full surround support—Process up to 7.1 surround mixes in up to 192 kHz resolution, with full metering on all channels
  • Front/rear linking mode—Work with surround sound material more easily and link channels for more consistent level management
  • AAX DSP optimized—Pro Limiter handles monster-sized Pro Tools|HDX mixes with ease, delivering exceptional sound quality and DSP efficiency
