Maybe you’d like to record in the Sydney Opera House. Or in the Grand Ole Opry. Or in the Manhattan Center, or in Wembley Stadium, or in Birdland. Or record dialogue in a stairwell, a church, a car interior, or on the Todd-AO scoring stage. For all of these—you want IR1.

Convolution reverb’s uncanny ability to reproduce hyper-realistic acoustic environments is well-known, but IR1’s 2,000+ impulse responses are what truly bring convolution reverb to life.

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.
