MP3 RECORDER

Above is the link for the free mp3 recorder that we use to do our tracks , what we do is set the mp3 recorder to stero mix so it picks up both mic and music together , then search for your desired track on youtube , search for a karaoke version , hit record on the mp3 player then play on youtube and sing your heart out , if your voice or music are louder than the opposite , then opening volume control and moving stereo mix either up or down will increase music/voice to suit
