When you first launch ScopeBox, it will run as "unregistered". To enable the full feature set of ScopeBox, you must enter a serial number in the Registration dialog. You may also visit to obtain a time-limited trial key, which will allow you to try all of the features of ScopeBox before buying.
By default the Audio Meter will show all channels currently reported by a source. However, many devices report a fixed number of output channels, which can waste valuable screen space displaying empty channels. If your capture device always sends eight channels to ScopeBox, but you are only using two, you can set channel count to 2 to only present the first two channels.
ScopeBox is a high end application and requires a lot of system resources to run properly. The application uses a number of techniques to actively monitor video processing and allocate CPU resources to ensure video is captured without frame drops. 2b1af7f3a8
