iSight Mic Records High Pitched Noise (SOLUTION)

If your built in microphone is picking up a high pitched noise/whine when recording with your iSight camera, this solution may work for you. It seems to only be a temporary solution, so you may have to repeat, but I do hope it helps you.

@danabobana Glad I could!

Your getting 60hz buzz from your other equipment like lights. Your best bet is to keep all power cables as far from your mic cable. You could also record/sample your room with just noise and super impose it inverted and it will cancel out your noise. You can also run a noise algorithm. Also consider buying a mic with a ground IE: XLR cable mic and interface don't buy usb mics.

@00viperXX Hey Luke, the mic is built into the computer, alongside the built in iSight webcam. I've tried recording with and without lights and the noise is there regardless. I've noticed the sound coming from within the computer. I think it's the camera...but maybe a fan. I'm really not sure. I just know a quick fix is to tap the top of the computer when the sound is heard. Makes it go away for a while.

@danabobana That noise can also come from two other places: wireless internet router and, if you have a Mac, anything plugged into the firewire (timer issue).

Very interesting. I just got a camcorder that is making recordings with the same noise. The fact that your noise clears up tells me that its not the analog audio signal. I will do some checking, but right now my best guess is the video AGC is wide open with the low light, generating a lot of processor hash and noise. You added light causing the AGC to clamp down the signal level and then moved back to your black background and no noise. Exercising the AGC fixes it. Interesting.

wow I hope that apple will recognize this problem and fix it.

I will give this a shot and hopefully it will work. Thanks for posting this quick fix.

the same type things happen to the ipod nano

This solution only worked when ambient reduction was on

@jedbeetle Ya, the light trick doesn't work that well for me anymore either. I've resorted to tapping the top of my computer (where the mic/camera is) during recording and it seems to eliminate the sound for a short while. When I was looking up a fix last year I really couldn't find anything worthwhile.

@aceblade I've been trying this and it does nothing for me D: are the forums really barren???

This high pitched noise is second only to self-destroying batteries as the absolute crappiest feature of a laptop, and this MacBook has both problems...
