"An impulse response," explains Stefan Feistel, managing director of AFMG, "contains all the information that can be derived from the measurement of a linear, time-invariant system, such as loudspeaker systems, rooms and the like. Magnitude and phase transfer functions can be extracted from an impulse response just as all parameters of electro and room acoustics. In order to evaluate STI, RT, C50 or many other parameters of room acoustics, you need to have a full-length impulse response - and SysTune is the only software able to deliver this in real time."
Developers at AFMG have been working on the topic of room impulse responses for three decades. With the rise of computer processing power, SysTune has been the first real-time audio measurement programme to deliver fluent, continuous and reliable results without the need for error-prone, manual delay tweaking. Refinement of SysTune's astute algorithms led to the filing of the patents in 2007.
