question 1: how many players can be part of the same swordfight?

answer: currently 2, algo does support multiple. Trick is to send multiple tones, but needs to make it faster.

question 2: we tried this, using short bursts of 17KHz sound. Have you tried using smaller bursts than 100ms?

answer: 100ms is not tone length. 25ms is the length. You record for 100ms, in hope of picking up the tone.

question 2a: what was the frequency band?

answer: two phones have different ranges - 0-11Khz, 0-8Khz.

question 2b: this is audible range. so what about background noise?

answer: high pass filter removes people's noise. Also correlation.
