Easy Editing, Convolution Sound

Algorithmic Reverb Familiarity
With IR1, editing convolution reverb can be just as easy as editing conventional algorithmic reverb. You’ll find familiar reverb parameters—like RT60 decay time, size, density, ER buildup, and a 4-band EQ to set damping.
Superior Shaping
Despite impulse responses being static, the envelope shaper allows non-linear responses—faster or slower decay, gated responses, tails that swell up before decaying, rhythmic chopping, and more.
Shift Into Reverse
The innovative Reverse mode reverses the tail, but not the original sound being processed. The result is ghostly, evocative reverb that still retains the intelligibility of vocals and instrument attack/decay characteristics.
Over 2,000 Spaces
The crown jewel of the package is over 2,000 meticulously recorded impulses of acoustic spaces, including venues from around the world—often with different seating positions and microphone polar patterns.
Impulse Customization
The IR1 separates the direct sound, early reflections, and tail, each with its own gain and predelay parameters. Also, you can trim the impulse start for an instant attack, or the end for a shorter reverb that needs less CPU power.
Create Your Own Impulse Responses
Want to sample an acoustic space whose natural reverb you love? Maybe sample a vintage spring reverb? IR1’s sweep tone makes it easy to create your own impulses. Download this sweep file, play it through speakers in your space of choice, record the result, and import the recorded sweep file into the plugin (see the IR1 user guide for full instructions).
