iZotope DDLY Dynamic Delay Effects Plug-In (Download)

The DDLY Dynamic Delay from iZotope is a plug-in featuring two delay lines that respond dynamically to the source material. You can adjust the threshold to split the signal based on transients, and then send the signal down two separate analog or granular delay paths. For instance, one could set up the delay on a drum track to only add echo to the harder attacks of the kick and snare, without adding delay to the buzz from the snares, room noise, or a sloppy high hat that would make the mix sound muddy or crowded.
