apulSoft apShaper is an audio effect plugin to add harmonic distortion 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 can simulate various types of distortion, including tape and tube saturation, wavefolding and analog bitcrushing. apShaper uses sophisticated algorithms to reduce the big problem of digital distortion - unwanted nonharmonic noise. It performs analog waveshaping using numerical integration. The distortion is applied to a continuous model of the audio signal. This reduces digital artifacts more than traditional oversampling could, especially if the transfer curve is not smooth (wavefolding/bitcrushing).

The three filter bands offer the same great quality without frequency squeezing at high frequencies. The included variable slope low-pass filter type allows smooth slopes not possible by traditional filtering - ideal to gently shape signals with large amounts of distortion applied. Four types of tone control bands produce recreations of vintage and modern guitar/bass tones.

Great plugin. odd that this the first review! Just tested the demo for version 1.0.1 build191117.


-The modulation panels adds great features to the all saturation circuit, making it possible to control when and how the saturation happens;

-The different algorithms for saturation sound really good (harmonic / tube / saturation / steps / wavefold) and how we change the shape it great;

-The filter types for Eq are enough for manipulating the sound! they are post-shaper, i believe;

-GUI resize from 50% to 200%, very nice.

-CPU wise - even in ultra mode doesn't "suck" much CPU and is great in the number of samples it introduces (using the compressor lookahead introduces some more samples has usual).

- Spectrum analyser makes it possible to visualize how the sound has changed in reagards the process made, is great, avoids 3rd party plugins for that task;

-Two programmable knobs for any plugin task, amazing feature;

-Phase input and output, many will think is not necessary, but when dealing with saturation many things can change along the process;

-Variable DC filter;

-MIDI controllable;


- Meters could display dbFS values;

-Alt /Ctrl + Click doesn't reset the knobs / sliders to default values;

Feature request:

-Introducing a module swap to change what comes first in the chain.

-Two saturation units to combine drives.

-more UI skins.

Thanks apulsoft, keep the good things coming.
