Spectrogram window is located on the right side of the plugin. This window displays streaming spectrogram in real-time, as well as recognized notes (marked with orange color). Spectrogram allows to estimate recognition accuracy and make decision about changing recognition parameters.
At the top of the spectrogram window the plugin displays chord names. The chord indication can be delayed using a slider on the option page. This can be useful if your host sends audio events to the AU module in big advance.
