Has anything like this happened to you?
Today, I experienced some wierd noises coming through my mixer , headphones and into my ProTools session.
These sounds even registered as little blips in the wav file. It sounded like someone was talking (very muted) , and I couldn’t understand it–but it caused me to re-record a number of times in order to get a clean audio file.
I remember at one of the radio stations I worked at, (WQFM-FM, Milwaukee), we had carrier current broadcasting a MUZAK channel simultaneously from our rock station’s antenna on the station’s roof. I recall our station engineer telling me, “It’s RF” , those ubiquitous and unpredictable radio frequencies we could hear through our headphones, and in the station’s signal. That was back in the 1970’s. Fast forward to the present, now with ever-present additional wired and wireless devices we all own, sound waves are all around us. No wonder.
I turned my mixer on & off- I was running ProTools, my MS Outlook and IE7. Could this noise have been some RF rolling off of some cell phone, Ipod, wireless internet, baby monitor or bluetooth nearby into my orbit …while I am trying to record a project for (don’t laugh, now) LG ?
Had my mixer or or mic cable become an unknowing antenna? I decided to do some research and fell upon this helpful decsription of RF at wisegeek. Another technical, but clear description was found in “What is Radio Frequency?”
Here’s my concern. Everything is already grounded, shielded and plugged into power strips and my APC battery backup. And it’s not a hum…it sounds like someone is talking.
If there are any suggestions, I’d like to know about them, and will share them here.
