Fiedler Audio is a German audio software developer founded in 2013, specializing in plug-ins for immersive audio, Dolby Atmos production, and reverb. The company has carved out a niche around spatial and 3D audio workflows, producing tools aimed at music producers, mixing and mastering engineers, and sound designers working across DAWs that don't natively support Atmos.

The catalog centers on the Dolby Atmos Composer and Dolby Atmos Composer Essential, which offer a simplified path for rendering Atmos music mixes outside of Dolby's own tooling. Surrounding these are the Spacelab series of immersive reverbs — including Spacelab Interstellar and Spacelab Ignition — along with the AD 480 Reverb (also available as a Reason Rack Extension), the Mastering Console for Atmos, the gravitas MDS mastering compressor, the Stage depth-enhancement processor, and armada, an immersive plug-in wrapper.

Fiedler Audio's products are distributed directly and through third-party retailers such as Plugin Alliance and Plugin Boutique. The company is best known within the immersive audio community for providing a non-Dolby route into Atmos mixing on stereo-only DAWs.

Fiedler Audio has 10 products cataloged on Equipboard, including FX Bundle Plugins, Mastering Suite Plugins, and Mastering Plugins.
