NEOLD is a German audio software company that builds plugins by modeling rare, one-off analog prototypes assembled from NOS (new old stock) components. The company was founded by three audio industry veterans: Roger Schult, an analog electronics designer who runs German Audio Lab and specializes in tube circuitry and vintage gear; Dominik Klaßen, who previously founded and managed elysia for over a decade; and Reimund Dratwa, a DSP expert who founded Fuse Audio Labs and has written analog-modeling code for Brainworx/Plugin Alliance and Black Rooster.

The company's catalog centers on faithful emulations of obscure or custom-built analog signal chains. Flagship titles include the V76U73, which models a Telefunken V76 preamp paired with a U73 compressor/limiter, along with BIG AL (tube saturator), U2A (optical compressor), WUNDERLICH, WARBLE, OLDTIMER (delay), U17, and RZ062. Plugins are distributed through Plugin Alliance in addition to direct sales.

NEOLD's niche is the intersection of boutique analog hardware craft and digital emulation — products are typically derived from hardware Schult builds by hand before Dratwa codes the DSP counterpart. The brand is aimed at engineers and producers looking for character-driven processors rooted in German broadcast-era equipment and rare studio components.

NEOLD has 7 products cataloged on Equipboard, including Saturation Plugins, Compressor Plugins, and EQ Plugins.
