apulSoft apShaper is an audio insert effect plugin to add harmonic content to audio signals. It combines a waveshaper with three filter bands and various modulation options - two lfos, a dynamics detector and user-configurable knobs.

apShaper comes with five shaper engines ranging from adding harmonic distortion to freely configurable polygonal wavefolding. The three filter bands come directly from apulSoft apQualizr2 and offer the same great quality without frequency squeezing at high frequencies. The included vari-slope low-pass filter type allows smooth slopes not possible by traditional filtering - ideal to gently shape signals with large amounts of distortion applied.
