[M4IF Technotes] MPEG4-CELP vs other speech codecs

[Biswajit Biswas]

Hi,
I am doing quality comparison between various speech codecs.
MPEG4 CELP  (ISO)
SMV (3GPP2)
GSM-AMR(3Gpp)
Can anyone suggest where can I get reference source code for SMV
(Selectable Mode Vocoder)? I have searched in 3gpp2.org, but could n't
get any. 
Can anyone suggest an alternative location?
With regards
Bis
