NUSofting is an independent audio software developer based in Reggio Emilia, Italy, founded and run by Luigi Felici. Luigi began developing audio software in 2001 under the name Dash Synthesis (later DASH Signature), before launching NUSofting as its own entity in 2003. As a one-person operation with occasional freelance collaborators, NUSofting has built a catalog of synthesizer plugins and audio effects for macOS and Windows in VST, VST3, and Audio Units formats.

The company is known for experimental, unconventional plugin designs that prioritize sonic exploration over emulation of existing hardware. Key products include daHornet bis, a reimagining of the classic EDP Wasp synthesizer; Modelonia, a hybrid physical-modeling instrument combining plucked-string and blown-bore models; Sinmad, which blends virtual-analog and physical-modeling synthesis with waveshaping and FM; and Peti SA, a physical-modeling harmonium and accordion plugin. NUSofting also offers several freeware instruments, including Noisetar, a noise-based synthesizer using purely mathematical generation, and Sinnah, a virtual-analog synth built around a resonant delay network rather than a traditional subtractive filter.

Under the banner "Fertile Audio Tools," NUSofting has expanded its lineup with accessible, often free or name-your-price plugins such as Psicogramma Key (a waveshaper/FM synth), Filter4Tongue (an experimental filter), Eugene Filter, and Sosir Freeze-Delay. The company's philosophy emphasizes "less replication, more exploration," encouraging musicians to discover their own sounds rather than chasing familiar tones.

Nusofting has 5 products cataloged on Equipboard, including Synth Plugins, Drum Machine, and Filter Plugins.
