Claim:
1. A method, comprising: receiving a first audio stream and a second audio stream; determining whether a first energy level for the first audio stream individually meets or exceeds an energy level threshold; determining whether a second energy level for the second audio stream individually meets or exceeds the energy level threshold; in response to determining that the first energy level for the first audio stream individually meets or exceeds the energy level threshold and determining that the second energy level for the second audio stream individually meets or exceeds the energy level threshold, computing a set of gains for at least one of the first audio stream and the second audio stream to create a dominance effect of the second audio stream over the first audio stream; generating metadata comprising the set of gains for at least one of the first audio stream and the second audio stream; generating an output audio signal comprising the first audio stream, the second audio stream, and the metadata comprising the set of gains; wherein the method is performed by a computing device, which comprises a processor.
