RecSound is a Windows application designed for recording sound from various
telephone lines (with adapter)
One line input of sound card gives two recording channels (left and right channels of stereo input).
Actually RecSound consists of two applications: the "RecSound core" and the "Control" application. RecSound core doesn't have any user interface, total control of recording system is provided by control application. RecSound core can be installed as Windows service or set to auto loading in application mode after Windows startup. Control application can be started anytime to listen audio records or change application settings. It doesn't work without RecSound core is started.
