MS GSM 6.10 - Specification - paulzazzarino - Jun 23 2:34:00 2005
I am trying t0 measure the amplitude from an MS-GSM 6.10 data stream.
While 3GPP has specs on various GSM codecs, I am trying to wade thru
and determine what or where I can find a description of the bits.
For example is MS GSM 6.10 FR? etc
any help is appreciated!

Like just about all Microsoft products, their GSM 6.10 does not follow the spec
precisely. The best resource I have seen is the actual GSM codec source code
Microsoft provided in the NT 4.0 DDK. That source code might still be in the
latest DDK, so that would be a good starting point.
