sonible is an Austrian audio technology company headquartered in Graz, founded in 2013 by graduates of the joint audio engineering program run by the University of Music and Performing Arts Graz and Graz University of Technology. The company builds AI-assisted audio plug-ins aimed at mixing, mastering, and post-production, alongside a smaller line of professional audio hardware including multi-channel amplifiers and immersive loudspeaker systems used in research and installation contexts.

sonible is best known for its smart: series of plug-ins, which apply machine-learning analysis to common studio tasks. Flagship titles include smart:EQ 4, an intelligent equalizer with instrument and vocal profiles and a reference-matching workflow; smart:comp 3, an adaptive compressor; smart:limit, smart:reverb 2, smart:deess, and smart:gate. The company also publishes the simpler pure: series (pure:EQ, pure:comp, pure:limit, pure:verb, and others), the learn: bundle for beginners, and a set of specialist tools such as true:balance, true:level, proximity:EQ+, and entropy:EQ+.

The brand has carved out a niche for itself among producers and engineers looking to speed up repetitive corrective tasks, and its plug-ins are commonly bundled and distributed through retailers like Plugin Boutique, Sweetwater, and Gear4music. sonible is part of the Audiotonix group, alongside companies such as Solid State Logic, DiGiCo, and Slate Digital.

sonible has 32 products cataloged on Equipboard, including EQ Plugins, Compressor Plugins, and Reverb Plugins. Most sonible products fall in the mid-tier range — professional-grade without flagship pricing.
