But in the SWF file formaat spec:
http://www.adobe.com/content/dam/Adobe/en/devnet/swf/pdf/swf_file_format_spec_v10.pdf
Coding format Audio format number Minimum SWF version
Uncompressed, native-endian 0 1
ADPCM 1 1
MP3 2 4
Uncompressed, little-endian 3 4
Nellymoser 16 kHz 4 10
Nellymoser 8 kHz 5 10
Nellymoser 6 6
Speex 11 10
So format number 6 is NellyMoser (which can have different rates depending on
the sample rate field of the sour object).
