I have almost convinced myself that Audio/AMR is not the same as GSM 6.10 -- can anyone please confirm or deny this? Here is an Audio/AMR reference implementation for x86 PCs: http://www.3gpp.org/ftp/tsg_sa/WG4_CODEC/AMR-Wideband/AMR-WB_Characterization_Phase/Executables/g7221%26amrnb400_exe.zip Does anyone have source to an AMR codec? I can't find it. > AMR is the mandatory format for voice message audio email attachments > according to the MMS (Multimedia Messaging System) ETSI cellular > telephone specification (ETSI 123 140), which incorporates the IETF MIME > and VPIM specifications in large part. > > The MIME type registration for Audio/AMR is presently at: > http://www.ietf.org/internet-drafts/draft-ietf-avt-rtp-amr-13.txt > > The AMR specification is: 3GPP TS 26.101: > http://www.3gpp.org/ftp/tsg_sa/tsg_sa/TSGS_06/Docs/PDF/SP-99562.pdf Best wishes, James
