Just wondered if anyone had any experience of deploying multiple AudioMoths (separated by some distance, was thinking 100 m apart) to localise sound sources?
Wasn't sure if clock drift would be a problem on the AudioMoths, or the degree of accuracy to which the clocks could be synchronised.
Cheers,
David
Hi David, It depends on how accurate you need the synchronisation to be compared to the relative time difference between events. When you set the time (either with the smartphone app or the desktop app) the time within each recording will initially be accurate to +/- 10 ms. However, the clock will drift relatively quickly - up to about 1 second per day. We have a GPS synchronisation solution that we've been experimenting with which will maintain at least 20us synchronisation between recordings, and we should be able to release some hardware and firmware for this later in the year.
