Sonimus is an audio software developer specializing in analog-emulation plugins for mixing, mastering, recording, and post-production. Founded in 2009, the company builds a focused catalog of tools modeled on classic analog hardware rather than a sprawling product line, operating under a "less is more" philosophy. The name combines Soni, from the Greek Sonitus (feeling of listening), with Mus from Music.

The company is best known for its console-emulation plugins — including Satson (a solid-state console emulation), Britson (modeled on a classic British 8014 console), and the A-Console, N-Console, and T-Console series — along with channel strips, compressors, and EQs such as TuCo (a warm tube-style compressor), Burnley73 (a 1073-style EQ emulation), StonEQ 4k, SonEQ Pro, and the simple tilt EQ Sweetone. A free version of SonEQ is also offered.

Sonimus products are developed by a small team of musicians, producers, and programmers, with distribution and support handled from the United States. The plugins are commonly discussed on audio engineering forums such as Gearspace and KVR Audio, where they are often cited for delivering analog-flavored coloration at an accessible price point.

Sonimus has 5 products cataloged on Equipboard, including EQ Plugins, Multi-Effect Plugins, and Channel Strip Plugins. Their gear is featured by 2 artists, with the strongest followings in Electronic. Notable users include Mat Zo and Tom Hades.
