Abstract: A streaming client device receives a bitstream, which includes an encoded audio signal according to an encoded audio signal version selected among multiple selectable versions, each having at least one personalization option among multiple personalization options. The bitstream also includes side information with configuration information and capacity information. The streaming client device: defines a personalization, by choosing a preferred selectable version based on the capacity information and the configuration information; selects an encoded audio signal version based on a current state of the external resource and the personalization, so that the capacity required by the selected encoded audio signal version matches the current state of the external resource; and decodes the received encoded audio signal or transcodes it onto another bitstream.
