01Overview

Convolution reverb reproduces a space by applying a recorded impulse response to your audio, which gives a more lifelike result than algorithmic models. IR-L is built for producers who want that realism without a complicated signal path. Waves says it draws on the sound quality of the IR1 audio engine and describes the library as covering a wide range of spaces, from small stairwells to large cathedrals. Standard reverb parameters keep the editing approachable.

Sound and Editing Controls for Convolution Reverb

The IR-L library includes a 4.8 GB collection of impulses that Waves describes as carefully curated and recorded with field-recording equipment. Each impulse can be shaped with standard reverb parameters, so you can adjust the reverb without working through a dense set of convolution settings.

You can trim the beginning and end of an impulse to remove unwanted sections and tighten the tail. Variable pre-delay runs from 0 to 500 milliseconds, letting you separate the dry signal from the start of the reverb.

Import Options and CPU Modes

Beyond the built-in library, you can import your own WAV files and third-party impulse files, which extends the plugin to spaces you have recorded or sourced elsewhere.

The plugin offers two CPU usage levels, and you can choose mono, mono-to-stereo, full stereo or efficient stereo processing. These options let you balance sound and processing load depending on how many reverb instances your session needs.
