Audio Ease are a group of music- and audio software developers based in Utrecht the Netherlands.
They are best known for Altiverb, the first and highest regarded convolution reverb. Convolution reverb creates reverb based on samples of the real world: Sydney Opera House, the Gol Gumbaz of india, or the company bathroom.
Speakerphone is a much younger product seeking to be the definitive speaker simulator. It not only holds samples of virtually every speaker imaginable, but also combines it with environmental sounds, static, sirens etc, to complete the image.
Snapper is newest. A small idea with big consequences. Basically: sound files in the Mac Finder are never again closed. Quicklook on steroids. Just watch.
When Audio Ease is not tweaking a filter or fixing their backup server, they are likely out there sampling a busstation or an antique telephone.
