Project overview

GuitarTuner listens through the microphone, identifies the played note, and sounds a cue when the instrument is in tune. It is designed for guitar but works as a chromatic tuner for other instruments, with an adjustable reference frequency. The prebuilt macOS release is Intel-only; Windows users need to install the Python dependencies and run the program from the command line.
