ABSTRACT:
A switching apparatus is constructed for discriminating a plurality of singing voices from each other based on a reference melody in order to pass the discriminated singing voices to different audio processes. In the apparatus, a plurality of input devices are provided to collect a plurality of singing voices separately from each other, each input device producing a voice signal which carries an individual melody of the singing voice collected by each input device. A plurality of output terminals are arranged to pass the voice signals separately from each other to the different audio processes. A switch circuit is disposed between the input devices and the output terminals to provide a plurality of electrical paths which are switchable with each other so as to distribute the voice signals from the plurality of the input devices to the plurality of the output terminals through the electrical paths. A controller device examines matching degrees of the individual melodies carried by the voice signals with respect to the reference melody so as to discriminate the voice signals from each other, and controls the switch circuit based on the examined matching degrees to switch the electrical paths to thereby route the discriminated voice signals from the plurality of the input devices to the plurality of the output terminals.
