SysRes is a program capable of playing and simultaneously recording two channels at rates up 48 kHz and display the recorded stimulus graphically. In addition, SysRes is able to perform synchronous averaging of a stimulated response such as distortion product optoacoustic emission (DPOAE). SysRes requires a high-quality sound card for stimulus generation and synchronous averaging, such as Pinnacle/Fiji from Turtle Beach or CardDeluxe from Digital Audio Labs. In addition, the Linux version of the program will currently only work on the turtle beach sound cards.
