Re: [Csnd] Simplistic approximation of air absorption (cutoff frequency)

Kicking some life in this old conversation, I just wanted to post a link to an article discussing calculation of air absorption, where there are some references to filter design that fairly well approximates the air absorption effect.
Hopefully it could be useful to someone.

Thanks.

Very cool. Seen a paper like this one before. I think there’s this info

in a vest pocket reference book I have. Will have to check that when

I get home. Very good.
