Default Can you give this a listen, weird mic noise

Hi Folks,

I have been borrowing a friend's Focusrite 18i20, which is about 18 more inputs than I normally use. I am thinking about getting a new interface, and he said I could borrow this one for a while, so figured why not.

I was doing some test recording with my pair of AT 3035's tonight and noticed a weird kind of rustling sound in the right channel. I figured it would was probably the environment but decided to switch to swap the mics left to right. Then I started hearing it my left ear. So I am kind of worried one of my mics might be broken. Can someone give this a listen and tell me if you hear a slight rustling kind of sound in the left channel? It would be most prominent at the end during the fade out.

A wee bit of moisture on the mike diaphragm can cause that sound to occur.

Thanks Rick. That is good to know. Is there a good way to fix this? Just leave the mic out till it evaporates?

thanks

Anton

If you have or can get some desiccant(silica gel) packs, put the mic with the packs in a ziplock plastic bag overnight. Dry rice in a stocking and mic in the ziplock bag can work also if you don't have any desiccant packs available.

Walmart may also have something similar.

You could also leave the mic on a stand and keep it powered up. If it's moisture, it will bake off in anywhere from a few hours to a few days. In severe cases, you can place an incandescent light bulb under the business end of the mic at the same time.

Swap cables, too. It sounds like what I've experienced from a low quality cable in the past.
