Abstract
The present document describes a method () for allocating bits to a frame () of a sequence of frames () to yield a bitstream having a constant average bitrate, wherein the frame () comprises audio data and metadata. The method () comprises maintaining () an overall bit reservoir () and maintaining () a virtual bit reservoir () being a subset of the overall bit reservoir (), such that bits for the metadata of the frame () are allocated from the virtual bit reservoir () and such that bits for the audio data of the frame () are allocated from the overall bit reservoir ().
