PSP Audioware Stompfilter

What PSP StompFilter Is For

PSP StompFilter is a creative effect plug-in dedicated to modulated filtering and movement of an audio source. It is used both to create rhythmic variations on synths and pads and to add an auto-wah-style articulation on guitars, keyboards, or bass lines. In electronic, hip-hop, pop production, or sound design, it enables transitions, build-ups, textures, and filter "grooves" that breathe, while maintaining dynamic control via its compressor.

Main Features

Modulated Filtering: From Subtle to Radical

At the core of PSP StompFilter is a filter capable of smoothly shifting from one character to another, with low-pass, band-pass, and high-pass modes. You can move from gradual darkening to more focused band effects, perfect for carving out space in the mix or transforming a static source into living material. The filter behavior is designed to remain musical, whether you seek a simple "sweep" or a very pronounced effect.

LFO and Envelope Follower: Expressivity and Control

The plug-in offers an LFO to animate the filter and gain, as well as an envelope follower to trigger movements based on the input signal's intensity. A major strength is the ability to cross-modulate: the envelope can influence the LFO, opening the door to more organic and "played" effects, between automatic wah, creative pumping, and filters that react to a drum hit or accents in a bass line.

LFO Randomization: Inspiring Imperfections

By adding an adjustable amount of LFO randomization, PSP StompFilter introduces slight irregularities reminiscent of analog circuit behavior. The result: less mechanical, more natural modulations, and a sound that remains interesting over time, especially on repetitive patterns (arpeggios, hi-hats, sequences, drones).

Integrated Gain and Compressor: Sculpt the Movement

Beyond the filter, PSP StompFilter includes gain processing and a compressor to stabilize or emphasize variations created by modulation. This is particularly useful for maintaining a controlled level feel when the filter and envelope become very expressive, or conversely, to highlight the rhythmic impact of an auto-wah on a guitar, Rhodes, or drum track.
