1. An apparatus comprising at least one processor and at least one non-transitory memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
obtain at least one audio stream, wherein the at least one audio stream comprises one or more transport audio signals, wherein the one or more transport audio signals is a first type of transport audio signals in a format;
obtain an indicator representing an at least partially different second type of transport audio signals in the format, wherein the indicator is obtained from a synthesizer configured to perform rendering to a user, and wherein the at least partially different second type comprises a target transport audio signal type; and
process the one or more transport audio signals of the at least one audio stream based, at least partially, on the indicator to generate one or more processed transport audio signals that is the target transport audio signal type.
