Yeah, one has to think of the 'microphone budget.' For microphone arrays, I think it's probably better overall (from the ecosystem management angle) to cover a wider non-overlapping region than getting a more comprehensive picture of a single point... The quality of the single-source classifier is the obvious scientific bottleneck, though; improve it, and everything else will work better. (We've also got plenty* of existing training data for this case.) So that's where we've been focusing most of the energy. * - depending on species, of course. See also: xeno-canto.org
