 RF64 can be used in the entire programme chain from capture to editing
and play out and for short or long term archiving of multichannel files.Due to the inconsistent usage of CUE data definition, the additional requirement that CUE chunk names be stored in an additional LABL chunk, along with the inherent 32-bit limitation of the CUE chunk pointer index, the 2009 RF64 format also defines a new 'r64m' marker chunk.The RF64 file format should fulfill the longer-term need for multichannel sound in broadcasting and archiving.
