cause transmission of the ambient sound limited audio information by way of the audio uplink;

receive other audio information from the at least one microphone;

receive an indication of an input indicative of the user not facing the apparatus; and

in response to the input indicative of the user not facing the apparatus, determine ambient sound limited audio information based, at least in part, on the audio information.

5. The apparatus of claim 1, wherein ambient sound limited audio information is determined based, at least in part, on an ambient sound directive that specifies a magnitude of ambient audio information to be comprised by the ambient sound limited audio information.

6. The apparatus of claim 1, wherein the memory further comprises computer program code that causes the apparatus to perform:

receive other audio information;

receive an indication of an input indicative of the apparatus being proximate to a user'"'"'s ear;

in response to the input indicative of the apparatus being proximate to the user'"'"'s ear, determine other ambient sound limited audio information based, at least in part, on the other audio information; and

cause transmission of the other ambient sound limited audio information by way of the audio uplink.

8. The apparatus of claim 1, wherein the memory further comprises computer program code that causes the apparatus to perform:

receive other audio information;

cause display of an interface element associated with ambient sound;

receive an indication of an input indicative of selection of the interface element;

in response to the input indicative of the selection of the interface element, determine other ambient sound limited audio information based, at least in part, on the other audio information; and

cause transmission of the other ambient sound limited audio information by way of the audio uplink.

9. The apparatus of claim 1, wherein the apparatus comprises the microphone.

10. A method comprising:

receiving, by an apparatus, audio information, from at least one microphone, for an audio uplink associated with another apparatus;

receiving, by the apparatus, an indication of an input indicative of a user facing the apparatus;

in response to the input indicative of the user facing the apparatus, determining, by the apparatus, ambient sound limited audio information based, at least in part, on the audio information; and

causing, by the apparatus, transmission of the ambient sound limited audio information by way of the audio uplink;

receiving, by the apparatus, other audio information from the at least one microphone;

receiving, by the apparatus, an indication of an input indicative of the user not facing the apparatus; and

in response to the input indicative of the user not facing the apparatus, determining, by the apparatus, ambient sound limited audio information based, at least in part, on the audio information.
