Separating technique for singing voice from music accompaniment is very useful in original sound type Karaoke instrument. We propose a real-time system to separate singing voice from music accompaniment for stereo recordings. Proposed algorithm consists of two stages. The first stage is a spectral change detector. The last stage is a selective vocal separation in frequency bins. Our system consists of a DSP board and a multichannel audio interface board. The DSP board is a TMS320C6713 DSK. And multichannel audio interface has six (three stereos) channels. The proposed vocal removal algorithms are embedded in DSP. Listening tests with extracted MR from proposed system show vocal separating and removal tasks successfully.
