Hi,

On
http://www.speex.org/docs/manual/speex-manual/node11.html#SECTION001140000000000000000
the bitrate for Speex Wideband mode 9 and 10 is
9 	34,400
10 	42,400

On
http://tools.ietf.org/html/draft-ietf-avt-rtp-speex-03
the bitrate for Speex Wideband mode 9 and 10 is
9       34.2 kbit/s
10      42.2 kbit/s

I believe the draft contains the right values:
E.g. mode 10

Narrowband mode 7 -> 492 bits
High band "mode" 4 -> 352 bits
Total: ( 492 bits + 352 bits ) x 50 packets/s = 42200 bits/s

Can this be corrected/clarified?

Best regards,
Chris
