Karaoke!

If you have ever traveled to the Philippines during a holiday and are unaccustomed to the culture there, the word Karaoke may make you want to run for the hills. I know I got very little sleep during a social aid trip I did down there a number of years ago... there was singing everywhere all the time!

Now that I have recovered from that lovely bit of culture shock I find myself wanting to do some parodies of songs for some random side projects I have on the go that require moving the vocals from the song similar to a karaoke tune. So say for instance you were thinking of making a music video of you singing, but you actually needed a backup band (say a claymation backup band, because your real band was off for the night - or something).  Anyway here are a couple of options I'd like to share with you on how to remove vocals from a track, completely free.

Option 1: go the internet suggested route using Audacity and subtracting the right channel from the left. There are a number of video tutorials out there on how to do this and it is pretty straight forward. This works because generally vocals are recorded in a mono channel, and then split between the left and right (so the wavelength is identical). When you invert one channel and subtract it from the other like this, in theory it should remove only the doubled frequency, being the vocals. I however didn't find this worked that well for the song I was working on (home-recorded folk bands apparently don't produce conventional mixes, who knew)



Option 2: Is super quick and worked great for me. It's a little plugin called Vocal Zap for iPhone or mac/pc that you can install and use with your favourite DAW software. And it works, so I would recommend this- unless you live in near Manilla and are the ladies who sang karaoke at 3am during the only reasonably temperatured hours of the night, in which case I would recommend something else.

**Note that neither method guarantees to totally remove the vocals in any track. However both are the best option for getting you as close as possible to a song with no vocals.
