RNC object has two modes: RNC and Farina. Value for mode is updated when user switches the tabs on the top of the main view. Third tab (‘Misc’) is used to store configuration data for both modes. Switching tab into ‘Misc’ does not update audio object mode. Fourth tab (‘AA Filters’) allows user to set filter coefficients for three sets, observe filters sets characteristic on appropriate graphs and check if coefficients on the filter set are stable. Switching tab into ‘AA Filters’ does not update audio object mode.
