Neyrinck is a San Francisco–based audio software company founded by Paul Neyrinck, an engineer whose prior work includes the design of products such as the TL Space Convolution Reverb, Digidesign D-Show EQ, Focusrite D2 EQ, and Orban Digital Optimod 8200. The company develops plug-ins and control-surface utilities aimed at Pro Tools users, broadcasters, and post-production studios.

Neyrinck is best known for its SoundCode line of plug-ins, which provide encoding, decoding, and monitoring tools for Dolby Digital (AC-3), Dolby E, and LtRt surround formats directly inside a DAW, removing the need for dedicated Dolby hardware. Titles in the family include SoundCode for Dolby Digital 2, SoundCode for Dolby E, SoundCode LtRt Tools, and the Broadcast Supreme Bundle.

Alongside the SoundCode suite, Neyrinck develops V-Control Pro, a software bridge that keeps legacy Digidesign/Avid control surfaces — including D-Command, C|24, Control|24, Pro Control, and Command|8 — working with modern DAWs such as Pro Tools, Logic Pro, Cubase, Nuendo, Studio One, and LUNA, as well as newer PreSonus FaderPort hardware. The company also makes the Spill metering plug-in and the V-90 Symphonic reverb.

Neyrinck has 2 products cataloged on Equipboard, including DAW Controllers and Flanger Plugins.
