RAL / Realtime Analyzer Light 2.0.0.2
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 realtime measurement function is entirely included.
It has the signal generator, Peak level meter, Power spectrum, 1/3 octave analysis, 3D graph (TEF), and Oscilloscope. It can be used broadly from a home audio, and a car audio to a concert hall.
