LANDR is a Montreal-based music technology company developed by MixGenius, best known for pioneering automated, AI-driven audio mastering. The platform launched its flagship online mastering service in 2014, applying machine learning trained on the adjustments mastering engineers make to produce release-ready tracks, and has since expanded into a broader end-to-end suite for independent artists and producers.

Beyond automated mastering, LANDR offers digital music distribution to streaming platforms such as Spotify, Apple Music, and TikTok, a royalty-free sample library, and a catalog of plugins and virtual instruments. Its product lineup includes the LANDR Mastering Plugin and Mastering Plugin Pro, which bring the cloud mastering engine into a DAW as an insert effect, alongside Samples, Distribution, and a marketplace connecting musicians with session players, mixing engineers, and other collaborators.

The service occupies a niche aimed at home-studio producers and DIY artists looking for fast, affordable mastering and release tools without hiring a traditional mastering engineer. LANDR's automated approach has been a frequent point of discussion in pro-audio communities such as Gearspace and Sound on Sound, where it is often compared with human mastering as a baseline option for demos, streaming releases, and high-volume independent output.

LANDR has 25 products cataloged on Equipboard, including Multi-Effect Plugins, Synth Plugins, and Virtual Instrument. Their gear is featured by 1 artist, with the strongest followings in Hip Hop. Notable users include Nas. Most LANDR products sit on the budget-friendly end of the spectrum.
