In one embodiment, at least one audio data frame having at least one channel is generated. Each channel is divided into a plurality of blocks. A sub-block partitioning scheme is selected, and a number of sub-blocks into which the block is to be partitioned is selected. The selected number of sub-blocks is chosen from numbers of sub-blocks available for the selected sub-block partitioning scheme. The block of audio data is partitioned into sub-blocks according to the selected number of sub-blocks, and the partitioned sub-blocks are coded according to a selected entropy coding scheme.
