    Properties:
    ------------

        * excitation (SignalObj), (SignalObj):
            signal information used to reproduce (playback);

        * device (system default), (list | int):
            list of input and output devices;

        * inChannels ([1]), (list | int):
            list of device's input channel used for recording;

        * outChannels ([1]), (list | int):
            list of device's output channel used for playing or reproducing
            a signalObj;

        * samplingRate (44100), (int):
            signal's sampling rate;

        * lengthDomain ('time'), (str):
            signal's length domain. May be 'time' or 'samples';

        * timeLength (seconds), (float):
            signal's time length in seconds for lengthDomain = 'time';

        * fftDegree (fftDegree), (float):
            2**fftDegree signal's number of samples for
            lengthDomain = 'samples';

        * numSamples (samples), (int):
            signal's number of samples

        * freqMin (20), (int):
            minimum frequency bandwidth limit;

        * freqMax (20000), (int):
            maximum frequency bandwidth limit;

        * comment ('No comments.'), (str):
            some commentary about the signal or measurement object;

    Methods:
    ---------

        * run():
            starts playing the excitation signal and recording during the
            excitation timeLen duration;
