Abstract:
An apparatus comprising: a coding rate determiner configured to determine a first coding bitrate for at least one first frame audio signal multi-channel parameter and a second coding bitrate for at least one second frame audio signal multi-channel parameter, wherein the combined first and second coding bitrate is less than a bitrate limit; a channel analyser configured to determine for a first frame the at least one first frame audio signal multi-channel parameter and configured to determine for a second frame the at least one second frame audio signal multi-channel parameter; a multi-channel parameter determiner configured to generate an encoded first frame audio signal multi-channel parameter within the first coding bitrate from the at least one first frame audio signal multi-channel parameter and configured to generate an encoded at least one second frame audio signal parameter within the second coding bitrate from the at least one second frame audio signal multi-channel parameter; and a multiplexer configured to combine the encoded at least one first frame audio signal multi-channel parameter and the encoded at least one second frame audio signal multi-channel parameter.
