as of January 30, 2003. (The DSSF3 is our best sound
measurement/analysis software and has been frequently
updated.)Quality sound measurement software
equivalent to at least US$10,000 hardware.The
software license of RAL costs just US$24, but RAL is
more functional than the usual FFT analyzer. General

It has the signal generator and FFT analyzer for
supervising distortion of the frequency
