FYI, we provide a function "parseGeneralConfigStr()" that will 
convert the ASCII configuration ('AudioSpecificConfig') string into 
binary form.  (See "liveMedia/include/MPEG4LATMAudioRTPSource.hh")

We also provide a function 
"samplingFrequencyFromAudioSpecificConfig()" that can be used to 
extract just the sampling frequency from the ASCII configuration 
string.  (See "liveMedia/include/MPEG4GenericRTPSource.hh".)  We use 
this function in "QuickTimeFileSink" when writing ".mov'" or "mp4" 
format files.
