Nembrini Audio Chromatic Tuner is a tuner plugin and iOS app for fast, accurate instrument tuning. Its large, bright, full-color LED display presents the tuning reading. Users can set the reference pitch to any standard, with A=440 as the default, and Drop/Capo mode transposes notes up or down by as much as one octave. The product page states tuning accuracy of ±0.01 cent. On desktop, the plugin supports VST2, VST3, AAX, and AudioUnits-compatible hosts. Listed requirements are an Intel-compatible or Apple Silicon CPU, 1 GB RAM, macOS 10.13 or newer or Windows 7 or newer, and a 64-bit DAW. The iOS app works on its own or as an AudioUnit v3 effect on iPhone and iPad. The listed plan is free for a supported plugin host or the iOS app. Nembrini Audio offers a searchable knowledge base and a form for support tickets. The company says it was founded in 2019 and specializes in digital reproductions of analog saturation circuits, with tools intended for musicians, players, producers, and mixing engineers.
