A system comprising: a first apparatus and a second apparatus, and configured to enable transmission of data between the first apparatus and the second apparatus, wherein: the first apparatus comprises means for: capturing audio generated by at least one participant as at least one participant audio object; rendering different audio to the audio generated by the at least one participant and at least one user of a second apparatus to the at least one participant as at least one private audio object, wherein the private audio object is associated with the participant by being rendered to the participant; the second apparatus comprises means for: obtaining from the first apparatus a spatial audio signal where the spatial audio signal comprises the at least one participant audio object and the at least one private audio object causing the participant audio object to be rendered in a first spatial location; and causing the private audio object to be rendered in a second spatial location so that the rendering of the private audio object is less prominent than the rendering of the participant audio object such that the user of the apparatus can distinguish that a type of the participant audio object is different from a type of the private audio object based, at least partially, on at least one of: the second spatial location being farther from the user than the first spatial location, an angular direction of the second spatial location from the user being farther from a main direction of the user than an angular direction of the first spatial location, or the first spatial location being located between the user and the second spatial location. the first apparatus comprises means for: capturing audio generated by at least one participant as at least one participant audio object; rendering different audio to the audio generated by the at least one participant and at least one user of a second apparatus to the at least one participant as at least one private audio object, wherein the private audio object is associated with the participant by being rendered to the participant; capturing audio generated by at least one participant as at least one participant audio object; rendering different audio to the audio generated by the at least one participant and at least one user of a second apparatus to the at least one participant as at least one private audio object, wherein the private audio object is associated with the participant by being rendered to the participant; the second apparatus comprises means for: obtaining from the first apparatus a spatial audio signal where the spatial audio signal comprises the at least one participant audio object and the at least one private audio object causing the participant audio object to be rendered in a first spatial location; and causing the private audio object to be rendered in a second spatial location so that the rendering of the private audio object is less prominent than the rendering of the participant audio object such that the user of the apparatus can distinguish that a type of the participant audio object is different from a type of the private audio object based, at least partially, on at least one of: the second spatial location being farther from the user than the first spatial location, an angular direction of the second spatial location from the user being farther from a main direction of the user than an angular direction of the first spatial location, or obtaining from the first apparatus a spatial audio signal where the spatial audio signal comprises the at least one participant audio object and the at least one private audio object causing the participant audio object to be rendered in a first spatial location; and causing the private audio object to be rendered in a second spatial location so that the rendering of the private audio object is less prominent than the rendering of the participant audio object such that the user of the apparatus can distinguish that a type of the participant audio object is different from a type of the private audio object based, at least partially, on at least one of: the second spatial location being farther from the user than the first spatial location, an angular direction of the second spatial location from the user being farther from a main direction of the user than an angular direction of the first spatial location, or the second spatial location being farther from the user than the first spatial location, an angular direction of the second spatial location from the user being farther from a main direction of the user than an angular direction of the first spatial location, or the first spatial location being located between the user and the second spatial location.
