A word about my last post. I didn’t mention that I was using the trial version of Sound Forge 8.0 and a trial of the Noise Reduction plug-in.

Is it possible that the trial versions insert artifacts? The randomness of the chirps are making me wonder…

I am using Sony Noise Reduction to take out a very complicated waterfall sound as background noise.

Here’s the problem:
When I am using Noise Reduction anywhere in the track (even sampling a completely silent portion of the track to use as the ‘noise’) I get chirps and other artifacts at random places. Even if I loop the same segment, the chirps are at different places in the loop.

No matter what settings I use, the chirps are present. Were it not for those artifacts, the waterfall noise reduction would be quite reasonable.

I’ve tried capturing large areas of noise and tiny tiny tiny ones – it doesn’t matter.

I’d be more than happy to provide an audio sample if anyone wants to try.

Thanks
