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 one 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. All time history and spectrum results are displayed in graphical format with cursor tools for precision amplitude analysis; results can also be saved in a text file. The program supports 16 Bit Rate and a sampling rates of 44.1 kHz.
