apulSoft apShaper is an audio insert effect plugin designed to enrich audio signals by introducing harmonic content. It integrates a powerful waveshaper with three distinct filter bands, providing detailed tonal control. The plugin features five unique shaping engines, ranging from harmonic distortion to customizable polygonal wave folding, enabling creative sound transformations.

The waveshaper employs advanced algorithms that minimize aliasing and digital artifacts, delivering a smooth and natural sound. This approach simulates ideal analog waveshaping through numerical integration, maintaining audio clarity even with complex shaping curves like wave folding or bit crushing. With only six samples of latency, apShaper is suitable for real-time use, making it a reliable tool for both studio production and live performance.

apShaper’s three filter bands provide high-quality tone shaping without compromising high-frequency content. The plugin offers a variable-slope low-pass filter that achieves smooth transitions not possible with conventional filters, ideal for refining heavily distorted signals. Additionally, multiple tone control options inspired by classic analog circuits allow users to sculpt bass, midrange, and treble frequencies with precision and character.
