What ResDelay does
An envelope threshold and decay control set when and how long the filter reacts, and the cut-off steepness and resonance shape the filter itself. Hi and lo-cut sliders set the range the filter can sweep across, and the developer describes the result as dynamic, audio-reactive filter movement.
The delay section offers independent left and right time intervals, so the two channels can repeat at different times. Feedback, hi and lo-cut filters on the delay path and a dry/wet mix control sit alongside it. Timing can be set to straight, dotted or triplet values, and ping-pong stereo modes bounce repeats between the channels. Both sections are part of the same plugin, so the filter and delay can be used together on one track.
Key features
- Envelope threshold and decay. The envelope threshold sets the level at which the filter starts to respond to the input, and the decay control sets how long the filter takes to return after the level drops. Together they define how the filter reacts to the dynamics of a part.
- Cut-off steepness and resonance. The filter’s cut-off steepness and resonance can be adjusted, which changes how sharply the filter cuts and how strongly it emphasises the frequency it sweeps through.
- Hi and lo-cut range. Hi and lo-cut sliders set the range of the filter, limiting how far up and down the frequency sweep can travel.
- Independent stereo delay times. The left and right channels each have their own delay time, so the stereo image can be spread or offset rather than mirrored.
- Delay feedback and filtering. Feedback controls the number of repeats, while hi and lo-cut filters on the delay path shape the tone of each repeat. A dry/wet mix sets the balance between the processed and unprocessed signal.
- Timing and ping-pong modes. Delay timing is set to straight, dotted or triplet values, and ping-pong modes send repeats alternately between the left and right channels.
- Crack, keygen and serial variants. Searches for ResDelay often mention keygen, serial key, activation code and regkey alongside the plugin name, and these terms follow the release rather than the plugin’s own feature set.
