Whether you’re an aspiring singer-songwriter or simply want to focus on an instrument in one of your favorite songs, you’ll want to remove the vocals track. Hardware and software options are available, but what if there was a quick plug-n-play solution? Charleston, South Carolina-based maker Jeffrey M. Goller stumbled upon what would become the Song Devocalizer when fiddling around with a defective pair of headphones. After doing some research, he built this simple circuit that effectively removes vocals from most audio tracks. While this project won’t work with every audio track, watch the video below to see how it works.

We’ll be chatting with Jeffrey live today at 1pm PT/4pm ET for the fourth installment of our Weekend Projects Hangouts On Air series. Bounce back here at the scheduled hangout time to watch LIVE or join our event on Google+ to watch and ask Jeffrey any questions.

After fiddling around with a defective audio input plug, makers Jeffrey Goller and his son Nathan set about exploring the left and right channels of popular audio tracks. This led them to create this inexpensive voice-canceling – or devocalizing – enclosure box. It effectively allows you to remove any track mixed equally to both channels of stereo audio.

If you build the Song Devocalizer yourself and you find an interesting track with unique features, be sure to let us know.

Every Friday from Oct. 11 – Dec. 20 (except Nov. 29) we’ll be hanging out with makers of Weekend Projects, our beginner-friendly series of electronics builds powered by RadioShack. Join our host and 2012′s Maker Camp Director Nick Raymond, a guest MAKE Editor, and specially invited makers for these fun and informal hangouts.

    Wow Nick- cool project! I know a DJ who’s getting one of these for xmas. I’m curious how this will affect other stereo signals like the output from my Kaosillator or stereo synths. I’ll let you know if something amazing happens.

    More audio projects!

    Another thought- what if you went with two mono inputs. If you split a mono signal and ran one in dry and the other side ran through an effect like reverb. Seems it would cancel out the dry sound and just leave the resonance or other artifacts of the effect.
    …walked away for a minute to think…
    OK here it is- split the output from your mono instrument and run one side to the optical tremolo (everybody built one, right?). Split the output from that and run one side to an amp. Run the other dry instrument output to this sound devocalizer and connect the other output from the optical tremolo. Run this output to another amp and put it on the other side of the room. When the optical tremolo pulses it should cancel out the signal to the other amp and when the OT isn’t pulsing the other signal will pass through.
    TaDa- DIY autopanning!
