Acustica Audio is an Italian audio software company founded in 2007 by developer and music producer Giancarlo Del Sordo and based in the province of Lodi. The company specializes in analog-modeled audio plugins for professional mixing, mastering, and sound design, built on proprietary sampling technology that captures the behavior of real hardware circuits.

Their first product, Nebula, uses a technology based on Vectorial Volterra Kernels to process audio through thousands of micro-samples taken from real hardware, with a library spanning preamps, equalizers, compressors, and reverbs. The Acqua plugin line followed as a more integrated experience, wrapping the same underlying technology in photorealistic interfaces that replicate specific hardware units end-to-end. Notable Acqua titles include Cardinal (console emulation), Olive, Stone, and Straw, among many others. In 2019, Acustica introduced machine learning and deep learning into their development pipeline to generate intelligent presets for their plugins.

Acustica Audio has built collaborations with Grammy-winning engineers and mixing professionals who use their tools on major commercial releases. The company also maintains an active user community and has developed co-branded plugins with hardware manufacturers and celebrated engineers.

Acustica Audio has 22 products cataloged on Equipboard, including Channel Strip Plugins, FX Bundle Plugins, and EQ Plugins. Their gear is featured by 11 artists, with the strongest followings in Electronic, Pop, and Hip Hop. Notable users include Luca Pretolesi, The Real Mike Dean, and Alawn.
