- SpectraScope is a simple Windows interface program allowing your computer to view up to two audio waveforms in either the time or frequency
domain. The program is a Windows soft panel operating as a dual channel oscilloscope and spectrum analyzer. The useful frequency
of operation is 20 to 10,000 Hz in the time domain and 20 to 20,000 Hz in the frequency
domain. The program uses the computer sound card to capture the audio input.
