Spectro Frequency Analyzer software provides you with the ability to perform real-time frequency measurements using your PC or laptop sound card. The program computes, in real-time, the averaged auto power spectrum of the time signal recorded by a microphone, connected to the sound card. Sampling rates of 8 kHz up to of 44.1 kHz (22050 Hz frequency span), 1 channel, and 16 bit are support. RMS or peak hold averaging analysis can be performed with linear or exponential averaging, applying the most popular window functions. Time History and Frequency Spectrum results are presented in graphical format with cursor tools for precision amplitude analysis. Results can be saved in a text file and imported into a spreadsheet program for additional analysis and presentation. The software is compatible with Windows 2000/Windows XP.
