"burst of air" sounds like a very low frequency impulse... if you can't 
rely on that part of the sound to be the same, you have to remove it, so 
that you are left with the part of the sound that is reliable, so that 
[bonk~] reacts reliably.

if the very low freqs are too much for the mic... because the lower freqs 
have inane amplitudes for their amount of energy... then what physical 
device constitutes an acoustic highpass filter that can remove the 
distorsion ? something that e.g. can remove much of the effect of wind 
blowing into a mic when trying to record outdoors... i don't know that 
stuff.

i just looked up "pop filter" when seeing that word in cgc's reply, and it 
seems like it's a highpass filter, though it doesn't use those words in 
the description I read, but I guess it from what they say about clipping 
and aspirated plosives.

but this article is weird, because it mentions the hiss but doesn't say 
what a pop filter does about hiss...
