Nembrini Audio is an Italian audio software developer founded by Igor Nembrini, who has worked on guitar amplifier plugin development for over a decade. The company specializes in digital emulations of analog saturation circuits — guitar and bass amplifiers, overdrive and distortion pedals, and studio processors — modeling component-level behavior and tuning the results by ear.

Their catalog centers on guitar-focused plugins, including amp simulators such as the Divided 11, Overdrive Special, Faceman, Hivolt 103, Cali Dual, BG Extasy, 8180 Monster, MRH810, and BST100 Super Overdrive, alongside pedal emulations like the Black Distortion (modeled on the ProCo RAT 2) and the Clon Minotaur Transparent Overdrive (modeled on the Klon Centaur). They also offer utility and effects plugins such as the IR Loader, Shimmer Delay, Acoustic Voice Pro preamp, and the PSA1000 Analog Saturation processor.

Nembrini Audio also develops Live Rig, a standalone plugin host designed for guitarists to chain together virtual amps and effects for performance and recording use. The company releases plugins in VST, VST3, AU, and AAX formats, and distributes a number of titles as free downloads alongside its commercial products.

Nembrini Audio has 12 products cataloged on Equipboard, including Amp Simulator Plugins and Distortion Plugins.
