What people are saying

"I record and mix original music score for film. Exponential Audio reverb plugins are the most useful and musical traditional reverbs that I have found on the market today. Whether it’s a stereo soundtrack album or a Cinema Atmos mix (or any other format), I use the Exponential Audio verbs extensively."

Dennis Sands, Sound engineer (Avengers: Infinity War, Godzilla)

"Exponential Reverbs have been an indispensable part of my recent journey. As a self-proclaimed reverb connoisseur with an army of hardware reverbs in my studio, Exponential’s NIMBUS and R4 reverbs are the only ones holding a candle to the outboard sounds I’ve gotten so used to over the years."

Richard Furch, Mix engineer (Outkast, Prince, Usher)

"I’m thrilled to see two of my favorite audio developers coming together, and very excited to see what kind of brilliant new toys and tools come out of it! iZotope and Exponential have both been on the leading edge of audio software for years and I find myself using both their products in literally every single mix that I do."

Will Files, Sound designer (Deadpool, Star Wars: The Force Awakens, Stranger Things)
