This is related to my motion tracking using piezos post(below) but is really a new topic.
I am attempting to track where a ping pong ball hits a table during a game using an array of microphones.
I need to ask if it is possible with a standard audio interface (in my case m-audio firewire audiophile).
I know that sound travels at 340m/s and I am estimating that it travels at 600m/s through the table.
I think that to detect the position of impact within 5cm I need to be able to access data from the microphones to within 1/12 of a millisecond.
I understand that it is possible to sync Max to an external clock or to change the length of (what it thinks is a) millisecond to get at the timing data.
I understand that I can sample audio at a frequency of 44,100.
But.....and this is the question
Is it possible to analyse the signals accurately at these sub-millisecond levels?
Anyone any thoughts?
