A computer-implemented method for selectively applying audiovisual enhancement functions to an audiovisual communications stream includes transmitting, by a sender computing system, an audiovisual communication stream to a receiver computing system, obtaining, by the sender computing system, one or more receiver perception feedback signals associated with the audiovisual communication stream, the one or more receiver perception feedback signals obtained as output from one or more receiver perception feedback models at the receiver computing system and descriptive of perception of the audiovisual communication stream by a user operating the receiver computing system, and applying, by the sender computing system, one or more audiovisual enhancement functions to the audiovisual communication stream based at least in part on the one or more receiver perception feedback signals.
