I've been noticing recently the recorder seems to make interesting noises every time I walk. Or sometimes in various other situations. When walking, it makes a faint click and sometimes even a pop, making some recordings unusable.
Sometimes it makes a faint buzzing sound that also makes some recordings unusable.
I am not plugged into AC power when the buzzing happens. I have plug in power enabled. Any ideas?
Hi omar,
Send some examples so I can find out.
pm mee and I give an email adres
Jack contact problems? Checked cables? (especially at connection points)
Changed battery? (or you may have "cold solder" somewhere in the recorder)
So or else - try to find if it's a matter of weak points somewhere (use headphone monitoring during checkup).
HI
I've uploaded 2 files that I think will give a good idea of what I mean. It's easy to doctor, but I'd rather know in case I may be driving them too hard, wearing them the wrong way hell anything could be a variable here!
In this recording, I had the recorder in my left pocket, the microphones were set at about level 70, low sensitivity. The microphone cable was not clamped or restrained and even when I did that it still did so. I was walking through the Jenson Beach mall with some stores around me.
Here are the recordings.

And the processed version, which gets rid of it somewhat

Feel free to use whatever version however you like, they will be uploaded here soon.
Thanks for the examples;
I did a lot of these in-ear recording and it's not easy to get a clean recording.
that vague tapping sound has the rhythm of walking. possibly the wires give some noise. I did tape the wire on my body. remark that clouting can make a lot of noise. Wear cotton clothing.
Thy to make some recordings in a quiet basement of an apartment or empty building on the same level, so it's more easy to find out. what the problem is.
My guess, the noise is close to you I can not find any interference from high frequent sources ore anything.
Ok,
So I tried something out. Yesterday night before I went out to dinner, I decided I'd try a different pocket I was carrying the recorder.
I normally carry the recorder in my left pocket but this time I tried the right. It seems to have solved the odd issue, for now.
Sometimes I do get some clicks or spikes of static but that's usually around server machines or some industrial machines etc.
Are these mics seriously that sensitive to RF noise? I'll have to listen to some recordings I made today, and find out. Not sure if I mentioned this before, I have the normal sensitivity version, since I have no problem supplying enough power to drive them to high volumes. I'm so glad I got them, boy these things can and do clip easily if your not careful.
