ISP Technologies announces Decimator X noise reduction pedals

ISP Technologies announced the Decimator X and the Decimator X G String on May 31, 2024, describing them as adaptive noise reduction pedals. The company says the design is covered by US Patent 11,641,183, with foreign patents pending¹.

The maker says the pedals center on a circuit it calls the Integration Release Window, which it describes as an adaptive release system. According to ISP, fixed-release noise gates and downward expanders force a tradeoff: a fast release suits staccato notes but produces "breathing" after each note, while a slow release suits sustained notes but a fast setting causes modulation as notes decay. The Integration Release Window is said to hold a slow release until a note's decay passes a set decibel threshold, so the release tracks only the negative peaks of the decaying audio envelope and adapts as the signal falls¹.

ISP says the patent covers the unique aspects of the Integration Release Window and that pending foreign patents reflect the technology's global significance¹. The announcement does not give prices, availability dates, control layouts or other specifications for either pedal.
