Abstract: An apparatus including circuitry configured to: obtain two or more audio signal sets, wherein each audio signal set is associated with a position; obtain at least one parameter value for at least two of the audio signal sets; obtain the positions associated with the at least two of the audio signal sets; obtain a listener position; obtain source position information; obtain values related to source energies associated with the source position information; generate at least one audio signal based on at least one audio signal from at least one of the audio signal sets based on the positions associated with the at least two of the audio signal sets and the listener position; generate at least one modified parameter value and a residual value; and process the at least one audio signal to generate a spatial audio output.
