An idea just popped into my head and I thought I would see if anyone has ever heard of such a thing...
I was wondering if there was a device which would have the ability to sample the analog background noise ("hiss") a sound system produces by taking a sample - basically, analyzing the signal with no music playing for X number of seconds, perhaps even with options like "Quick Sample" or "Long Sample" - and then, in much the same way as other noise reduction techniques, remove it digitally.
It could even have individual programmable presets to use with different analog sources since each source would probably have its own unique noise signature.
I'm not actually looking for or even need such a device. I was more or less just curious if something like it actually already existed or if it could even be DIY. On second thought, it almost sounds like the old dbx noise reduction system except in this case you are doing the encoding yourself based on the unique background distortion of your own equipment. I don't know. I was just curious.

Most noise is random. Therefore the only way to remove noise is to remove some signal too.
You know, I was thinking that as well. Like, the only way it would even come close to working would be some sort of comb filter to remove that segment of distortion.
Anyway, I really appreciate the feedback to my silly little thought. Take care, all! I'll be back!
Comb filters can often sound rather strange. They will have the same effect on music and noise. Not a solution.
Exactly. Thanks for replying.
