D16 Group Audio Software is a Polish software company based in Katowice that launched in 2006. The company was founded by a team of musicians and developers who wanted to bring the sound of iconic hardware into their digital setups but couldn't afford the original machines. Their first major release, Phoscyon — a emulation of the Roland TB-303 bass synthesizer — established them as specialists in faithful recreations of classic hardware.

D16 Group's product lineup centers on virtual instruments and audio effects. Their instrument catalog includes drum machine emulations modeled after legendary Roland hardware: Nepheton (TR-808), Drumazon (TR-909), and Nithonat (TR-606), alongside the Phoscyon 2 acid bass synthesizer and PunchBox kick drum synthesizer. Their flagship synthesizer, Lush-2, is a multilayer polyphonic instrument. On the effects side, the SilverLine collection spans a wide range — Decimort 2 (bit crusher), Devastor 2 (multiband distortion), Toraverb 2 (reverb), Repeater (delay with 23 modeled vintage delay devices), Tekturon (multitap sequenced delay), and several modulation effects including Syntorus 2 (chorus), Fazortan 2 (phaser), and Antresol (flanger).

D16 Group's plugins are available in VST, AU, and AAX formats for macOS and Windows. The company has built a following among electronic music producers, with users including Jean-Michel Jarre, Richie Hawtin, Chris Liebing, David Guetta, Robert Babicz, and Stephan Bodzin.

D16 Group has 39 products cataloged on Equipboard, including Drum Machine, Distortion Plugins, and Synth Plugins. Their gear is featured by 54 artists, with the strongest followings in Electronic, Pop, and Rock. Notable users include emma essex, Aiden Jude, and Rob Swire. Most D16 Group products fall in the mid-tier range — professional-grade without flagship pricing.
