Our VAS does not split songs by silence. It split songs by 'kernel streaming'. Windows opens an audio stream when it is asked to play a new song, VAS can detect this and record this new song as a new file. In other words, if there is silence in one song, VAS does not split it. This is our unique feature, only VAS can split songs by kernel audio streaming. It is more accurate than those audio recorders that split songs by silence because many songs also contain silence internally.
Give a try with the VAS systray recording command, then you will understand it. Also read:
