I require a backing Track for my VCE Music performance piece “Paranoid Android” for my end of year exam, with the acoustic rhythm part in the first third and the electric lead parts (solos) removed from the backing track. I’ve successfully attempted to remove the guitar using the “vocal remover” function, although the sound quality of the track is terrible.
How do you improve the sound quality of a track using Audacity? I’ve tried using the “normalize” function, although it doesn’t do anything to improve the track.
I’m currently using Audacity on Mac OS X 10.6.8. My guitar teacher and I have tried everywhere to look for another track, but can’t seem to find one with our specific requirements.
The track I’ve downloaded to edit in Audacity can be retrieved from the link below
I assume you have removed more than you were intending to remove. You can perhaps control what you remove more tightly with Robert J.H.'s 2D Stereo Toolkit . Put the .ny file in your Audacity Plug-Ins folder and restart Audacity.
I can’t tell you how best to operate the plug-in for your material or if it will help much. You will have to wait for Robert to appear. But if you are aiming to make a demo CD for your exam, I think you will find your selectively-removed backing will always sound weird.
Filters can make it sound better. You can often remove steady low level noise with Noise Removal with few audible artifacts. You can remove aggressive mouth noise in a vocal with a high pass filter or de-esser.
If the OP is talking about quality reduction as a result of using Vocal Remover, you can’t easily “fix” that except by removing less or changing what you remove.
