Resound is a software audio delay effect processor that emulates the sound and operation of vintage magnetic-tape echo units. Whilst not a direct copy of any one particular model, it takes features from several of the classic delay devices, and unites them into a convincing and pleasingly retro sounding effect.
Resound not only models the characteristic mechanical noise present in hardware magnetic-tape units, but also allows the noise to be controlled; from gentle warmth and distortion, to noisy, gritty, and unstable. The sound can be shaped further using the moveable highpass filter. And with feedback set beyond a certain intensity, Resound is even capable of self-oscillation.
Resounds echoes can either be synced to the host tempo (expressing delay times as musical subdivisions of a beat, each echo will be exactly in time with the host) or in free-time mode (allowing any delay time, up to 2 seconds.) The reverse mode adds further flexibility: by playing each delay backwards, Resound can produce unique effects beyond what hardware magnetic-tape units are capable of.
True independent stereo processing means that left and right channel separation is preserved. Resound is also capable or running in mono, or even mono to stereo.
With optimized audio algorithms that wont overload your processor, rock-solid stability, and easy integration with any MIDI hardware controller, Resound is ideal for live work. With a simple and intuitive interface, flexible Bank and Program management, and total parameter automation, Resound fits right into your studio environment.
Resound is available for Mac OS X v 10.4 and above, Windows XP and above, and Linux, in Audio Unit, VST plugin, RTAS for Pro Tools 7 and above, and Standalone application formats.
