Adam Monroe's Delay

Adam Monroe's Delay is a free VST AAX and AU effect plugin for Windows and OS X. There are many free and commercial delay effect plugins, but I wanted to make my own unique delay. Interesting features of this plugin include: - ping-pong panning that is synced to the delay time, so that each delay sounds like an echo sweeping from left to right. - built in high and low pass filtering, so that the frequency of the delay can be filtered, well leaving the original dry signal intact. - mix, panning, and panning-width controls.

The end goal was to make a highly parameterized delay plugin that could emulate some of the classic delay sounds like slapback, as well as create new and interesting effects, and package them in a comprehensive preset list and GUI, that the end user could easily navigate. The development of this plugin was restricted to the delay effect itself. Early on, the idea of a "time stretching" delay effect you might find on some digital and analog delay pedals as you change the delay time - for example, the rimshots on the Bauhaus song "Bella Lugosi's Dead" - was toyed with, but due to developmental restraints was ommitted from the final version of the plugin. Future versions of this plugin might include this feature.

Perhaps the most interesting feature of this plugin is the option to set the high pass and low pass filters to linear or exponential. Setting to exponential creates interesting effects like hisses and clicks, as the filtering folds-back on the delay buffer. This effect works best at 44.1 kHz, but many sample rates are supported.

I have updated this plugin to version 1.2. I've added a "dry mix" knob and around 25 presets. The new preset have a bit of a focuse on spatial delay effects...I wanted to make delay sounds sort of like you hear in Jerry Goldsmith's score for Alien and other weird horror scores. Check out the "spatial presets" mp3. There is also now support for macOS Big Sur and Arm64.

A delay VST AU or AAX plugin effect isn't that difficult to program - delay effects are relatively simple algorithms to implement. The interesting part is how to implement and manipulate simple concepts to produce interesting results.
