Dual/multi channel FFT real-time audio analysis software. Uses live program material as reference or self-generated signals. Measure frequency response, impluse response, phase, ETC, RT, STI, RTA mode, and more. SysTune is an indespensible tool for tuning audio systems and doing just about any audio or room analysis. SysTune is quickly becoming the new standard in live-sound audio measurment systems. Some unique features to SysTune are real-time Impluse response, real-time ETC, real-time RT, real-time STI, real-time Multi-channel averaging. The free demo works forever and does not require registration. It is however limited to one average, about a 1 second FFT size and no saving. This free demo is a useful RTA that transcends other software RTAs that aren't free.
