Welcome to SpectraPLUS-RT
SpectraPLUS-RT is a powerful dual channel spectrum analyzer. The program interfaces with any Windows compatible sound card to provide real time spectral analysis. It supports Narrowband, 1/1 Octave and 1/3 Octave measurements and includes a Recorder and a Signal Generator utility which produces tones, pink noise, white noise, and swept or stepped sinewaves. Although all signal processing is performed on the CPU, real-time performance is possible with today's machines.
