Audio 'Codec Tag 26481' may be requested when Ogg Vorbis CODEC for MSACM is missing. This one may work also AC3Codec. Audio 'Codec Tag 49' may be requested when GSM 6.10 Audio Codec is missing.

Full Rate (FR or GSM-FR or GSM 06.10 or sometimes simply GSM) was the first digital speech coding standard used in the GSM digital mobile phone system. It uses linear predictive coding (LPC). The bit rate of the codec is 13 kbit/s, or 1.625 bits/audio sample (often padded out to 33 bytes/20 ms or 13.2 kbit/s). The quality of the coded speech is quite poor by modern standards, but at the time.
