Stimulator High Frequency Stimulator High Frequency Stimulator is a simple plug-in to enhance or restore high frequency content on the source material. High Pass Filter with variable cutoff frequency. Stereo Spread control to enhance stereo image. All settings independent for both stereo channels.
Effect Only switch.
Factory presets Bypass function. HF Stimulator works this last way. How it works The transform uses a biquad high pass filter with variable frequency setting followed by a soft waveshaper. It generates harmonic content not present in the original material. The waveshaper algorithm is a modified lookup version of cosine waveshaping, with restricted constants to avoid clipping and double precision drive control.
