Noise Reduction Process

All this while I have been thinking & experimenting a lot with the help of people like George & online videos to get a grasp on the technique to improve vocal signals for people having very moderate hardware setup like me. Process of Noise reduction helps remove the distorting frequencies being created by Fans, Ac, Cpu Fan, SMPS fan, etc which gets mixed up with the vocals or instruments which are being recorded through the soundcard. All we do generally is mute the parts where there are no vocals or instruments are present but actually we fail to remove the noise from the whole body of the track. So how to remove it? The answer is Noise Reduction Process. Yes it is as easy as it sounds. Few softwares like Adobe Audition 3 comes with a VST known as Noise Reduction. All we have to do is to select a small area, not too less not too much & select Capture Noise Reduction Profile & then it captures the distorting frequencies there. Then select the entire file & hit ok. All those distorting frequencies are almost gone from the entire file as those frequencies captured by the Noise Reduction Profile will be of the same frquency range throughout the track. There are a few setting which you can tweek to get even a better desired result. Like increase the negative value of decibles by which the noise is going to be reduced, attack rate, percentage, etc. I hope with this method many suffering from background noise & resulting in a distorting mix will get immence help in achieving a much more clearer signals without much of the disturbing noises.

I invite everyone in Muziboo to participate in this discussion actively & share their knowledge with everyone.
