14. A method comprising:
obtaining a spatial audio signal, where the spatial audio signal comprises, at least, at least one participant audio object and at least one private audio object, wherein the at least one participant audio object is generated by a participant, and the at least one private audio object is associated with the participant, wherein the at least one private audio object is configured to be rendered to, at least, the participant and a user in a communication call comprising audio, wherein the at least one private audio object is not configured to be rendered to at least one further participant in the communication call, wherein the at least one participant audio object is configured to be rendered to, at least, the user and the at least one further participant in the communication call;
causing the at least one participant audio object to be rendered, to the user, in a first spatial location corresponding to the participant; and
causing the at least one private audio object to be rendered, to the user, in a second spatial location corresponding to the participant so that the rendering of the at least one private audio object is less prominent than the rendering of the at least one participant audio object such that the user can distinguish that a type of the at least one participant audio object is different from a type of the at least one private audio object, wherein the type of the at least one participant audio object comprises an audio object configured to be rendered to a plurality of participants in the communication call, wherein the type of the at least one private audio object comprises an audio object configured to be rendered to a subset of the plurality of participants in the communication call, wherein the subset of participants is at least partially different from the plurality of participants,
wherein the first spatial location is at least partially different from the second spatial location, wherein a spatial relationship between the first spatial location and the second spatial location is configured to indicate that the at least one private audio object is associated with the participant.
