A.O.M. is a Japanese audio software developer that builds professional plug-ins for mixing and mastering engineers. The company is best known for its Invisible Limiter series, a transparent mastering limiter designed to minimize the audible difference between the original and processed signal, with subsequent generations released as Invisible Limiter G2 and G3 in VST, VST3, AU, AAX, and CLAP formats.

Beyond the limiter line, A.O.M.'s catalog spans dynamics, EQ, spatial, and utility tools, including the tranQuilizr and tranQuilizr G2 equalizers, Nu Compressor and Tau Compressor Plus, the DeSibilizer de-esser, Track Symbiosis ducking processor, Stereo Imager D, Cyclic Panner, Sakura Dither, and the Kujaku convolution-based multi-effect. The company also offers a Total Bundle license that covers its full plug-in lineup.

A.O.M. has built a reputation in the post-production and mastering community for clean, technically rigorous processing rather than character-driven analog emulation, and its plug-ins are commonly cited alongside other transparent mastering tools in discussions of true-peak limiting and broadcast-grade workflows.

A.O.M. has 4 products cataloged on Equipboard, including Limiter Plugins, FX Bundle Plugins, and Bit Crusher Plugins. Their gear is featured by 16 artists, with the strongest followings in Electronic, Pop, and Rock. Notable users include Zedd, Pogo, and TheFatRat.
