Spectro Spectrum Analyzer consists of a Frequency Analyzer and Octave Analyzer with the ability to perform real-time acoustic analysis on your PC with a sound card. The Frequency Analyzer computes the averaged auto power spectrum using RMS or peak hold averaging with a linear or exponential weighting. The Octave Analyzer computes the averaged 1 octave or 1/3 octave spectrum using RMS or peak hold averaging with a linear or exponential weighting. Linear, A-weighted, B-weighted or C-weighted amplitudes can be chosen for both FFT and Octave analysis.to perform real-time FFT and Octave analysis with the use of your sound card. Exponential and linear averaging are available applying the most common window functions. The program is compatible with Windows 2000/Windows XP.
