Tone Projects is a small Danish developer with an outsized reputation in mastering circles. Uni-L, its mastering limiter, is routinely mentioned alongside limiters costing several times more, thanks to a transparent sound that holds transients together even at streaming-loud levels. The brand’s processors favour depth over sprawl: fewer plugins, each refined across years of development with input from working mastering engineers. That patience shows in the details — dithering, oversampling and metering are handled with unusual care. Plugins run on Mac and Windows in VST3, AU and AAX formats and arrive as instant downloads from VST Vault with both platforms in a single purchase. If your masters are the weak link in your releases, start with the limiter. Then browse the full VST plugins catalogue for the rest of the chain.
