I haven't recorded vocals in a few months. I was trying to do that today, but I was getting weird artifacts throughout the vocal take. It was driving me crazy, because this never happened before. I tried everything I could think of. I recently set up a wireless network, so for the heck of it, I disconnected the wireless network, and sure enough, thankfully that fixed the problem. 

FWIW, I never shut my wireless network off and have never had any problems.

It's weird because it only affected the mic. Everything was fine when recording guitar.

What sort of mic?  I'm guessing a capacitor...   with a screen grounding problem....

You scare me Karyn.

I have my DAW connected via wireless to my office computer and via Ethernet to another machine that contains my sound library and have never had any recording or playback problems that can be traced to either wireless or Ethernet.  Surfing the internet is a whole other matter entirely and should not be done for a variety of reasons when recording.

The less RF you have floating around, the better. One potential problem occurs if there are dissimilar metals that form small crystalline structures over time. These can basically act like crystal radios (not that anyone would know what those are, but I digress...) that rectify the RF and thus create signals in the audio range. 

I just picked up a new Wireless Mouse and Keyboard combo, made by good old Mircosoft, It does the buzzing thing when you move the mouse around??. So I traded back with my old Logitech Combo and the interference is gone now. 

Wi-Fi adapters can cause DPC Latency Spikes, and lots of folks temporarily disable them just prior to launching a Sonar session, then enable them again right after finishing with Sonar.
