MAAT is a German-headquartered audio software company specializing in high-fidelity plugins for mastering, mixing, and audio measurement. The name is an acronym for Mastering Academy Audio Tools, reflecting its origins under founder and mastering engineer Friedemann Tischmeyer alongside co-founders Dr. Christoph Musialik (CTO and DSP specialist), Oliver Masciarotte, and head of development Nils Petersson. The team's combined background spans roles at companies including Sony, Universal, Sennheiser, Lexicon, Apple, and Studer, and the company's lineage includes an agreement with German DSP house Algorithmix that informs several of its products.

The catalog is organized around three families: equalization, effects, and measurement. EQs include the thEQblue, thEQred, and the flagship thEQorange linear-phase equalizer, plus the SantaCruzEQ. Effects include FiDef JENtwo (a psychoacoustic enhancer), RSPhaseShifter (a digital implementation of Roger Schult/German Audio Lab's W2324 hardware), and the LIN family of dithering plugins such as LINpro. Measurement tools include DRMeter MkII and DROffline MkII for dynamic-range and loudness analysis, and 2BC multiCORR for multi-channel correlation. Free utilities such as 2BusControl and GŌN round out the line.

MAAT's design language emphasizes minimalism — visually unobtrusive interfaces, sans-serif labeling, and an explicit focus on sonic fidelity over feature sprawl. The plugins are aimed primarily at mastering engineers and high-end mixing workflows rather than general producers, with an advisory board that has included audio metering expert Ralph Kessler and analog designer Roger Schult.

MAAT has 20 products cataloged on Equipboard, including Utility Plugins, EQ Plugins, and Metering Plugins.
