Abstract

Provided is a karaoke apparatus which is connected between a song accompaniment machine and an amplifier and has a Universal Serial Bus (USB) host play function and a vocal reduction function. The karaoke apparatus includes a sound source input unit inputting therein a sound source being output from an external storage device, a vocal component extraction unit extracting a vocal component from the sound source being input through the sound source input unit by using an independent component analysis algorithm which finds out a particular left/right sound source ratio corresponding to the vocal component, and an audio output unit outputting an audio in which the vocal component extracted from the sound source is reduced.
