[linux-audio-user] OT Good material for DIY headset microphone.

[Alex Polite]

This is really OT.

I'm thinking of doing some experimentation with audio
beamforming[1]. For this I need to construct my own headset
microphones, with multiple microphone capsules per headset. Getting the
capsules, the microphone wire and doing the soldering should be dead
simple.

But I have no idea as to what material to use for the frame. A very
thick metal wire surrounded in some kind of foam, maybe? Wire is good
because it's easy to form during construction of the headset, but bad
because it's also easy to deform when using the headset.

The ideal material would be some kind of plastic that behaves like
thick metal wire until you bake. Then after you've baked it, it should
behave more like the plastic used in ordinary headsets and headphones.
