I had 3 things and points with that noise reduction.
A, noise can be reduced, but with 3 drawbacks. Number 1, by reducing the noise, if you have a band opening it can change the clarity of the audio. Because remember when two or more station is on the same frequency you hear that modulation and the other station in the distance. The noise filters can only do their part to press away different noises, but it can't prevent them entirely, without preventing the audio.
So let's use the example of the 24 second clip. In the first example, the flat audio, which by the way, if someone used a bit of treble reduction the high hissing sound could be delt with that way. The second part of the clip though registers that, if a band opening happens, and say for example on the frequency of kzz48, you hear 5 other stations, eventually the noise filter may get confused as to whether or not you are canceling out voice, or noise. I guess the one thing that would be a good test is to make the signal gradually weaker to see how much the threshold is, before the sound is blocked.
Item 2, separate notice, KZZ52 is back to streaming. I had to correct an audio issue with a patch cable as the jack I was using to run the audio through was trying to outsmart me, so I moved the patch cable to my microphone input jack on the computer. Seems to have solved the problem, minus the detail that thankfully I'm streaming mono since the patch cable is mono.
Just an interesting question, does anyone know if the web based software defined radios are accessible to the blind?
Just wondering.
I hope my audio insite gives you something to look at.
Ssorry if I missed something, I'm doing this on literally no sleep.
Thanks
Brandon.
