LANDR

LANGR is a music creation platform from LANDR Audio Inc. of Montreal, Canada. It commercialized AI mastering back in 2014 and now positions itself as an "end-to-end production suite for musicians," bundling mastering, distribution, samples, plugins, and collaboration into one subscription.

Core capabilities

• AI mastering: upload a mix and get a finished master within minutes; the engine builds a per-track processing chain (officially no presets), supports reference-track matching and album batches, and outputs 24-bit HD WAV
• Mastering Plugin: the mastering engine inside your DAW (VST3/AU/AAX) with real-time monitoring while mixing
• Music distribution: 150+ streaming/social platforms, you keep 100% of royalties, releases stay online permanently even after canceling
• Samples and plugins: 3M+ royalty-free samples, 70+ plugins, plus in-house Synchro Arts (VocAlign/Revoice Pro)
• Collaboration and education: Sessions real-time collaboration, 200+ online courses, and a REST Mastering API for developers

Who it suits Budget-conscious independent musicians, bedroom producers, podcasters, and creators who want one subscription covering mastering through distribution and are fine with an English-language interface.

Differentiation and cautions The moat is breadth plus category first-mover advantage: distribution is weaker than DistroKid, samples thinner than Splice, and mastering control falls short of iZotope Ozone — but it wins on one-stop convenience. Be aware: stem separation appears to be licensed AudioShake technology; plugin counts contradict across official pages (70+ vs 40+); no Chinese site; Trustpilot sits around 4.0 but is polarized, with 1-star reviews concentrated on subscription cancellation and refunds; G2 has only 3 reviews. In January 2026 it acquired Reason Studios, adding a DAW to the lineup.
