LATENCY, mostly TOTAL LATENCY

[Zlartibartfast]

the popping or clicking you hear is caused by timing errors/buffer under-runs. You don't hear it in the recordings because of the caching algorithms used in the disk-writing process (different buffers).

yes, it is related to latency. It might be completely beyond your control, unfortunately.

I've noticed it gets worse the more people there are in a session.....
