        channels. And likewise if you're doing an input-only app.

        @param minAudioInputChannels    the minimum number of audio input channels that the application needs
        @param maxAudioInputChannels    the maximum number of audio input channels that the application needs
        @param minAudioOutputChannels   the minimum number of audio output channels that the application needs
        @param maxAudioOutputChannels   the maximum number of audio output channels that the application needs
        @param showMidiInputOptions     if true, the component will allow the user to select which midi inputs are enabled
        @param showMidiOutputSelector   if true, the component will let the user choose a default midi output device
        @param showChannelsAsStereoPairs    if true, channels will be treated as pairs; if false, channels will be
                                        treated as a set of separate mono channels.
