eaReckon is an independent audio software company founded by Philippe Decuyper, based in Verlinghem in northern France. After years of consultancy work in audio software and electronic drums, Decuyper launched eaReckon as a solo venture focused on crafting high-quality audio effect plugins for VST, VST3, AU, and AAX formats on both Windows and macOS.

eaReckon's flagship product, EAReverb 2, is a 100% algorithmic true stereo reverb featuring six distinct algorithms — including Natural, Plate, Auditorium, and Reverse modes — along with three operation modes (Pro, SE, and POS for spatial positioning). Computer Music magazine praised it as "one of the best algorithmic 'verbs on the market." The company's other notable plugins include EARebound, a multi-tap delay with 16 delay lines that scored 9/10 in reviews for its combination of flexibility and ease of use; EARevolve, a rotary speaker and stereo chorus plugin that doubles as a spatial positioning tool and stereo widener; and TransReckon, a transient shaper lauded by Computer Music as "one of the finest transient shapers we've seen/heard." eaReckon also produced the ANALOG87 series, a channel strip bundle comprising a sidechain compressor, sidechain gate/duck, four-band EQ, brick wall limiter, and full-featured channel strip, which earned Editor's Choice and Performance awards from Computer Music.

Despite its small scale as a one-person operation, eaReckon has earned a reputation among mixing and mastering engineers for plugins that punch well above their weight, with reviewers consistently noting the quality of their audio processing algorithms and thoughtful interface design.

eaReckon has 10 products cataloged on Equipboard, including Reverb Plugins, FX Bundle Plugins, and Virtual Patchbay Plugins. Their gear is featured by 1 artist, with the strongest followings in Electronic. Notable users include Thomas Gold.
