Noise Reduction Addons - A personal perspective

I found a neat little noise reduction VST that I started playing with in Cakewalk Home Studio. Let me say that I have tried the audacity application and the noise reduction tool and I think the free VST I found works a whole lot better.

Now mind you I am still not a fan of noise reduction for audio review for 2 reasons.

1) It garbles the voices and makes the understanding of the audio up to interpretation. Also listening through the audio and picking up on subtle variations becomes much more difficult when the audio is processed via cancellation which is usually what you do to remove noise.

2) You get what you pay for. Free is never THAT good. (unless you're a pirate, then I can't help you there.)

The free VST can be found by searching the VST's on the KVRaudio.com website. http://www.kvraudio.com/get/4153.html Easy to find. The program is superior in that it not only does profiling, but it shows you the resulting settings of the profiling, in case you need to make adjustments. Something you won't find in audacity last I checked.

That being said, I was going over some of the audio that I did find on the lemp mansion audio. Most notably, the time of 5:09:28 contained what I though of as a voice saying "get off the bed". This was following a voice at 5:09:25 which sounds like a child voice saying "get off the bed". This of course is not what I hear when running the audio through the noise reducing software. I'll post the audio, because it's easier to hear because of the software, but what I heard originally, is not what I hear now. In the new audio, you can hear a voice saying "get out". Fairly straight forward, I would think.

Anyway, I am of the mind that you shouldn't rely on just one thing. I mean, if you want to be objective and thorough in your analysis, you can't do that.

I followed audacity back when it was called cool edit. Back when that program originated, cakewalk was in its infancy and windows was in version 3.1. I'm feeling old now.

I would imagine that someone would find a way to isolate just the kind of audio that you're not wanting in the output, but when it comes to ghosts, I just get the itching feeling that the reason we get those sounds is because of that background noise.

I guess it's kind of like how you can trick the eyes to see infrared light. Which I will have to post at another time.
