Maybe we're working at cross purposes, I didn't hear any shrill, sharp buzzing in the test clip, either. Just the occasional crackle. Koz

Thanks, Gale and Robert. I tried the lowering the EQ. Moved all the sliders above 800 Hz all the way down and get muffled sound and the buzz is still there. What are you trying to get rid of? I thought you meant the "crackle" distortion that is there slightly in the background noise and a...

Sure but what and where? the reason I'm interested in high sample rates is that I'm not always doing the usual thing :D I have an old XP computer that runs StereoTool to feed a transmitter with FM MPX audio.

One of each, four hp earbuds(in other words, everything I tested) It seems to only happen after listening to the recording for a while (source or edited), regardless of whether it's on my...

(snd-avg s 7 7 op-average) Put the code into the nyquist prompt and press OK. The value 7 is the amount of samples that are averaged. Higher values result ...
