I have not used the noise reduction feature.
I will have to wait until I get home to check that out. I'm thinking it may have to do with the audio driver. I can reduce the volume but I can't increase it enough. I had a previous version of the software on my old computer and I didn't have that problem.
I checked my Sound Forge software last evening and I don't seem to have the noise reduction plug-in you referred to. Also, it looks like that's something that applies when you already have a sound file to edit. My problem is evident when attempting to record an audio stream from a website. I will set up an account with my home e-mail later this week and re-submit the question from my home computer where I can try things more efficiently. In the meantime, thanks for your suggestions.
I set up a new account with my home e-mail because it's problematic accessing my work e-mail from home and vice versa. As it turned out, another expert was able to remote in to my home computer last night and download another audio driver, and the problem has been fixed. Thanks again for your help.
