From the App Store: GliderVerb is a “Reverberator with Glissandos” simulating a room gradually changing its shape. It is an expanded version of an algorithm created by James McCartney for his Supercollider 2 programming language.!
The original algorithm had no user-variable parameters: this device adds a series of parameters to create a wide palette of effects; from evolving reverberations to granular disintegration to smooth resonances.!
