01Overview

IR1 Convolution Reverb is an effects plugin in the reverb category from Waves. Instead of relying on algorithmic models, it applies recorded impulse responses, so the reverb takes on the character of the space it was captured in. The included library is 4.8 GB and covers a wide variety of acoustic environments. Beyond the built-in impulses, the plugin can load your own WAV files or third-party impulses, and it includes a sweep file for capturing new ones.

Sound, Impulses and Editing Controls

IR1 is built around its impulse library. The developer says every impulse was recorded with premium field-recording gear, which gives the reverb a realistic sense of space. Each impulse can be adjusted with several editable parameters, so you can shape a captured space to fit your track rather than using it exactly as recorded.

The reverb envelope can also be reshaped to produce non-linear effects, useful when you want a tail that behaves differently from a natural room decay. Waves also notes that the plugin can reproduce classic digital reverb hardware, so it covers vintage-style sounds as well as realistic rooms.

Channel Modes and Custom Impulses

IR1 offers mono, mono-to-stereo, full stereo and efficient stereo processing modes. Choosing a mode lets you match the reverb to the channel layout of your source, from a single mono track to a full stereo bus.

For sound design or specific spaces, you can import third-party impulses from the internet or load your own WAV files. The included sweep file lets you record impulses from your own spaces and use them inside the plugin.
