Surreal Machines Impact v1.1.1 (WinmacOS)

Impact is designed to help with the more nitty-gritty, detail-oriented aims of transient shaping. The multi-channel processor is switchable between one, two or three bands of transient modification - this means that different frequency bands can be adjusted independently, so that if you wanted to emphasize the attack of some airy hi-hats while, in the same sample, dulling the attack of a low-rumbling kick drum, you could do simply by adjusting the Attack and Sustain controls for each frequency band.
As part of its dynamic processing chain, Impact also includes four switchable styles of analog-modelled saturation, along with a final processing section that includes a clipper, limiter and a maximizer designed specifically to work with transient materials. This ensures that you are not only able to shape your transients exactly how you want, but you can also add some additional character to your sounds in the process.
