I'm going to assisting with a musical for a school I sub in, as an acting teacher/vocal assistance but with this school it becomes a bit of a challenge. The school is in multiple buildings, and we don't have access to a band room so in the past the director/teacher would just play the song and they'd have to sing over it to rehearse. And it's not one with a karaoke listing, so I'm attempting to try and get the audio to rip out the vocals myself, but my ability to do so is limited. Originally I could MacGyver something with Audacity using invert and an addon to help with the vocals, and I can get the normal voices down to very little without sacrificing too much of the music, but the "All" singing parts blow out any of my abilities to do so without compromising the song itself.
Yes I know the easiest way would be to get someone to play the songs and I record it, but I'm trying to improve my own abilities to be more independent and it is definitely easier for me to learn and do something techwise than self-teach myself the piano. Which is ironic, because I could sing well but I can't play an instrument to save my life. So yeah any help you guys might know, would be fantastic, side note. I have a PC, no Mac, I'd be doing this at home mostly otherwise I'd open up Mac as a work option.
