What is Relab?

Relab refers to Relab Development, a company that creates professional audio plugins used in music production, mixing, and sound design. The company is best known for developing high-quality digital effects that emulate classic studio hardware while adding modern features for digital workflows.

Relab Development specializes in reverb and spatial audio plugins, which simulate how sound reflects and travels within physical spaces. These tools allow producers and audio engineers to place sounds within virtual environments such as rooms, halls, or plates, helping create depth and atmosphere in a mix.

One of the company’s most widely known plugins is LX480 Complete, a digital reverb plugin that recreates the sound of the legendary Lexicon 480L Digital Effects System, a classic studio reverb unit used on countless professional recordings. Relab’s plugins are designed to closely replicate the sonic character of this hardware while providing modern controls and workflow improvements.

Relab plugins are commonly used inside digital audio workstations such as Ableton Live, FL Studio, and Logic Pro. They are popular among mixing engineers, producers, and composers who want professional-quality reverbs and effects to enhance their music productions.
