block wind noise on built-in mics? at DVinfo.net

Robert Bobson · August 14th, 2007, 02:34 PM

has anyone tried to block wind noise on built in camera mics? I thought about just taping some kind of soft cushion foam over them. thought I'd ask before I started experimenting. The camera is mounted on a bike rider who's going FAST!

Thanks in advance ~

Can you just turn off the mic? I dont know what kind of usable sound you'd be getting on the underside of a moving bike.

On my builtin mics, I have a furry windscreen for it, just like you'd get for an off-cam mic. Depending on your camera, you might be able to find one (I'm using one on my GL1, the same one fits my DVX also).

I wanted the sound of the chain and breathing and grunting...!

The camera is an older sony. I'll check online to see if someone makes a windbreaker.

does yours attach like a "car bra"?

thanks ~

no, mine slips over the mic like it would on an off-camera mic, its just much much smaller. If your mic is flush with the cam, you will probably have to build your own.

here's an idea:

get a 1.5" square of longhair faux fur (from a craft/fabric store)
get a 1.5" square of 1/8" thick soft foam (from a craft/fabric store)

glue the foam to the bottom of the fur, let dry

using thick rubber bands or velcro straps, place and secure the square directly over your mic.

the long fur is what actually cuts the wind noise.

Hi Robert,

Here's what I've done for some of my cams.

If you can't come up with an effective windbreaker, how about getting a little introduction to the art of Foley and recording it indoors with the bike locked into a stationary frame of some sort? Use an audio recorder or your PC along with a decent mic to capture the sound FX and then lay it in against your picture during post.

thanks for the responses. I'll try the fabric store first!

put an external mic on the back of the driver

I use the pop filter from an AT822 mic fitted over the Canon HV20 cam mic. The air gap in the filter fits right over the mic, blocks all wind.
Cheers.

DPA make a blimp that works extremely well, not a dead cat kind of thing at all. But it's pretty big and expensive. Almost no HF attenuation.

But as has been suggested, why not put the bike on a dyno and record the sounds needed.
