(en) UER, « Tech 3306 - MBWF / RF64 : An extended File Format for Audio » [PDF], : « The file format is designed to be a compatible extension to the Microsoft RIFF/WAVE format and to the BWF and its supplements and additional chunks. It extends the maximum size capabilities of the RIFF/WAVE and BWF thus allowing for multichannel sound in broadcasting and audio archiving. », p. 5
(en) UER, « Tech 3306 - MBWF / RF64 : An extended File Format for Audio » [PDF], : « The reason for the 4 Gbyte barrier is the 32-bit addressing in RIFF/WAVE and BWF. With 32 bits a maximum of 4294967296 bytes = 4 Gbyte can be addressed. To solve this issue, 64-bit addressing is needed. », p. 7
(en) UER, « Tech 3306 - MBWF / RF64 : An extended File Format for Audio » [PDF], : « With the advent of Windows 2000 Microsoft introduced the multichannel extension to its RIFF/WAVE file format, called Wave Format Extensible. The main purpose of this file format was to support multichannel audio in PC gaming applications. The Wave Format Extensible channel mask contains 18 “#define” settings specifying different loudspeaker positions (or channel allocations). », p. 6

(en) UER, « Tech 3306 - MBWF / RF64 : An extended File Format for Audio » [PDF], : « The problem arises that a recording application cannot know in advance whether the recorded audio it is compiling will exceed 4 Gbyte or not at end of recording (i.e. whether it needs to use RF64 or not). The solution is to enable the recording application to switch from BWF to RF64 on the fly at the 4 Gbyte size-limit, while the recording is still going on. », p. 9
