Sweetsonics released Laser, a precise sidechain plugin for Mac & Windows – AU / VST3 / AAX.
Laser draws reduction envelopes for transient signals, but it also recognizes continuous signals. One-click action gives a good starting preset in few seconds that can be tweaked easily afterwards. The algorithm is especially designed to recognize the transient signals.
Transient and continuous detection modes work for different applications. The transient mode provides extremely fast and precise envelopes for reduction and boosting! It works perfectly with drum and percussion material.
