ATKTransientSplitter is a specialized mono audio plugin designed to separate an input signal into its transient and sustain components. This process allows producers and engineers to manipulate the attack and body of sounds independently, enhancing control over the dynamics and texture of the audio. By isolating transients, the plugin helps in refining percussive elements or emphasizing the rhythmic impact within a mix.

The plugin is based on a unique transient shaping approach that applies different filters to the transient and sustain segments of the signal. It utilizes adjustable parameters that influence the timing and behavior of these filters, enabling precise shaping of the attack and release characteristics. These parameters control aspects such as the size of the analysis window, attack and release times for both fast and slow filters, and the ratio of influence between these filters, providing nuanced control over how the transient and sustain parts evolve over time.

Additional features include threshold and slope settings, which determine how the sustain level responds once it surpasses a certain power level, allowing for dynamic swell effects. The softness parameter adjusts the smoothness of the transition between transient and sustain processing, helping to avoid harsh or unnatural artifacts. Together, these controls make ATKTransientSplitter an effective tool for detailed transient manipulation, improving clarity and punch in mixes while maintaining the natural feel of the original sound.
