Waves Smack Attack is a powerful transient shaper designed to give you precise, intuitive control over the attack and sustain of any audio source. Whether you need to add punch and snap to drums, tighten up bass, or increase the presence of guitars and percussion, Smack Attack's independent attack and sustain controls let you reshape the dynamic envelope of your signal with ease. A real-time waveform display visualizes transient activity as you work, while the mix knob enables smooth parallel blending for natural-sounding results.
