I was recording a show last week (David Ford @ The Georgian Theatre) and when I was listening back I noticed some occasional distortion in the right channel.
Around 75% of the show sounds great, but I would love any opinions on what caused the distortion/interference/whatever it is.
Here is a sample track in Mp3, which is where it is the most prominent.
http://www.mediafire.com/?4fccdjibxy1I was set up using CA STC-11 Cards (With Standard Windscreens) > CA ST9000 pre (+10 Gain) > iRiver H320 (+6 Gain).
The mics were mounted on a stand at about 7' AB around 20' from the stage at the very back of the room.
I set up just to the right of center/board. The entrance doors were to the right, which was not ideal, but the bar was off to the left which would have been worse.
Here are the things I have considered that might have been the problem.
(i) Moisture in the capsule -
Possible after a few very hot and humid shows the previous week, but I would think that it would be more of a constant distortion if this was the case.
(ii) A loose Capsule -
I have checked and this doesn't seem to be the case, also I would expect this to be more constant.(iii) A bad connection on one of my miniplugs (either not inserted properly or a bad wire) -
Again possible, but I have some tracks which are perfect and only three or four which show distortion.(iv) My right mic was picking up a draught from the opening/closing door or a noise from the hinge -
While this sounds weird I am leaning towards this without having been able to do any home testing.
(v)
*Insert your suggestions*I will do some tests when I have a chance, but I have another show coming up and would love to have any opinions to work with as I don't think I will have enough time to do much testing beforehand.
Thanks for your time.
Dave.
