recorder placement

Hi all,

I've come across many posts here where people say they've put their recording device "near" the door, the wall, the window etc.

It seems like many underestimate the power of structure-borne noise. Ever heard of a contact microphone (aka wall listening devices)? The same principle can be used with any normal microphone or recorder (like a phone).

- remove any casing from the phone/recorder
- put the phone/recorder in direct contact with the door/wall/window or whatever
- the best results you'll get if the phone/recorder exerts minimal pressure towards the object's surface. Thing of a box, a shoe or whatever that either pushes the recording device towards the surface, or creates a gap in which the phone/recorder can be placed at a ~45°angle, so its own weight holds it (with the microphone side) towards it.

If you never tried that before, you'll be surprised how much more you can capture.

That's right, the better contact the better. I recommend recorders that the microphone is completely in contact and thus avoid part of the ambient sound. The ideal is to find a natural hole such as the gap between the door and the floor. the result is spectacular.

And what recorder with a microphone do you recommend? Or which microphone you recommend? I'm doubting to buy a Samson CM10b boundary microphone for this use?
