Yeah, we were chatting about the possiblity of something like this in the new audio mixer – would be pretty easy to add a single delay line per source that changes based on the source distance. Could result in realistic doppler effect too. Might hook something like this up on an Epic Friday (we have friday’s every other week where we can do “experimental” fun features). Typically, in games, this isn’t desired but it’s a cool idea, for sure. At least as a toggle-able option in sound sources or at the project level.
