What Nembrini Audio Chromatic Tuner is
Nembrini Audio Chromatic Tuner is a free tuner plugin and iOS app for tuning instruments. Its large, bright, full-color LED display presents the tuning reading, and users can set a reference pitch; A=440 is the default. Drop/Capo mode transposes notes up or down by as much as one octave. The product page states a tuning accuracy of ±0.01 cent. On desktop, the plugin supports VST2, VST3, AAX, and AudioUnits hosts on macOS and Windows. Listed requirements include 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. On iPhone and iPad, the app works standalone or as an AudioUnit v3 effect. Nembrini Audio provides a searchable knowledge base and a support ticket form. The company says it was founded in 2019 and makes digital reproductions of analog saturation circuits, with tools intended for musicians, players, producers, and mixing engineers.
