- Of particular interest to many users will be the CPU load (excessive CPU load may cause sluggish behaviour or freezing of the computer), and Audio latency. Apart from DDC bandwidth, CPU load may be minimized by reducing the Demodulator filter length (...
- Note: When measuring sensitivity using SINAD, it is very important that the Audio Filter is enabled and the cut-off frequencies (and for FM measurements, also the de-emphasis) are set according to the specified test conditions. Proper audio filtering ...

The CPU speed directly influences the maximum selectivity and DDC
bandwidth that can be achieved with this receiver. The receiver may be still
usable on slower computers, but with some compromises, for example using
only one of the two receiver channels and/or reduced maximum achievable
selectivity and DDC bandwidth. Other background processes and programs
running simultaneously on the computer may also adversely affect the
receiver’s performance.
