Audio Samples

Reversed Looper

A tremolo Rhodes line, first the dry signal, and then with Resound mixed in. Here Resound is set to Reverse delay mode, synced every half a bar, and with such a high feedback rate that it acts as a looping device. The audio in this demo is faded out at the end, but the feedback can be set high enough that the loop will play forever.

Dub Drums

This demo features a short, snappy drum beat, first played dry, and then routed through Resound. Resound's Time parameter is gradually reduced from 500ms down to 5ms, which when combined with the high feedback rate produces the classic pitch shifted dub effect.

Basic Retro Delay

A simple ARP Odyssey synth line through a phaser, first heard dry, and then with the Resound wet mix gradually increasing. The wow and flutter of the magnetic tape is particularly noticeable here on the repeated signal.

Loomer Resound

About Loomer Resound

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.

Resound's 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 won't 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 macOS, Windows, and Linux, in AAX, Audio Unit, VST plugin, and Standalone application formats.
Native 64-bit versions available for macOS AAX, Audio Unit and VST; Windows AAX and VST; and Linux.

An evaluation is available for free download, with the following limitations:
  • User created Program and Bank configurations can be saved, but not loaded.
  • Output will be periodically interrupted, approximately every 20 seconds, by a short moment of silence.
Purchasing a licence will remove these evaluation limitations.

Buying a Resound licence directly from us entitles you to lifetime free updates for Resound.
