Position tracking with contact microphones

Hi all,

I want to track the position of attacks (footsteps) on an MDF or wooden floor, by using contact mics.
Just read the 2008 post “audio tracking” by “bungalowbill”, where people adviced on using the time differences of the sounds arriving at different microphones.

However, I was thinking of using the differences in peak amplitudes. In other words, sound will be louder if closer to one microphone. I can’t get the patch quite stable enough though.

Does anybody have advice on this? Would it even be possible?

regards,
Woody

It’s definitely possible, though if you’re looking for a high level of accuracy, it’s not quite as easy as comparing amplitude.

Do a web search for tangible acoustic interfaces and you should find some information about something very similar.
