Default Speex Codec.

I'm new to ventrilo, because ventrilo is new to Mac. I was very excited to download this today, because I could finally communicate with guild mates on World of Warcraft. When logging onto my guilds ventrillo server, i get the message that there server uses GSM 6.10 codec not Speex. My guild said they were unable to change it to speex. Is speex inferior to GSM? could someone please explain why no one on WoW uses speex? thank you.

I am not sure about inferiority, but GSM is the default codec when you install a codec. If the guild has access to the ini file, they can change the codec easily to Speex.

I'm also wondering the same thing. I cannot connect to my guilds Vent server due to this problem. Any ideas?

Well, basically. If the guild can open the ventrilo_srv.ini (which is a text file) file wherever it is hosted. There are these 2 lines:
VoiceCodec=#
VoiceFormat=#

And depending the quality you want the audio chat you change that number:

Codec\Format\Description:
0\0\GSM 6.10 (8 KHz, 16 bit) 1625 bytes/sec
0\1\GSM 6.10 (11 KHz, 16 bit) 2210 bytes/sec
0\2\GSM 6.10 (22 KHz, 16 bit) 4420 bytes/sec
0\3\GSM 6.10 (44 KHz, 16 bit) 8905 bytes/sec
1\0\DSP Group TrueSpeech (8 KHz, 16 bit) 1056 bytes/sec
2\0\Lernout & Hauspie (8 KHz, 16 bit) 600 bytes/sec
3\0\Speex (8 KHz, 16 bit, 0 Qlty) 424 bytes/sec
3\1\Speex (8 KHz, 16 bit, 1 Qlty) 620 bytes/sec
3\2\Speex (8 KHz, 16 bit, 2 Qlty) 865 bytes/sec
3\3\Speex (8 KHz, 16 bit, 3 Qlty) 1110 bytes/sec
3\4\Speex (8 KHz, 16 bit, 4 Qlty) 1110 bytes/sec
3\5\Speex (8 KHz, 16 bit, 5 Qlty) 1502 bytes/sec
3\6\Speex (8 KHz, 16 bit, 6 Qlty) 1502 bytes/sec
3\7\Speex (8 KHz, 16 bit, 7 Qlty) 1922 bytes/sec
3\8\Speex (8 KHz, 16 bit, 8 Qlty) 1922 bytes/sec
3\9\Speex (8 KHz, 16 bit, 9 Qlty) 2384 bytes/sec
3\10\Speex (8 KHz, 16 bit, 10 Qlty) 3168 bytes/sec

3\18\Speex (16 KHz, 16 bit, 7 Qlty) 3070 bytes/sec
3\19\Speex (16 KHz, 16 bit, 8 Qlty) 3560 bytes/sec
3\20\Speex (16 KHz, 16 bit, 9 Qlty) 4344 bytes/sec
3\21\Speex (16 KHz, 16 bit, 10 Qlty) 5324 bytes/sec
3\22\Speex (32 KHz, 16 bit, 0 Qlty) 669 bytes/sec
3\23\Speex (32 KHz, 16 bit, 1 Qlty) 1061 bytes/sec
3\24\Speex (32 KHz, 16 bit, 2 Qlty) 1306 bytes/sec
3\25\Speex (32 KHz, 16 bit, 3 Qlty) 1551 bytes/sec
3\26\Speex (32 KHz, 16 bit, 4 Qlty) 1943 bytes/sec
3\27\Speex (32 KHz, 16 bit, 5 Qlty) 2433 bytes/sec
3\28\Speex (32 KHz, 16 bit, 6 Qlty) 2874 bytes/sec
3\29\Speex (32 KHz, 16 bit, 7 Qlty) 3266 bytes/sec
3\30\Speex (32 KHz, 16 bit, 8 Qlty) 3756 bytes/sec
3\31\Speex (32 KHz, 16 bit, 9 Qlty) 4540 bytes/sec
3\32\Speex (32 KHz, 16 bit, 10 Qlty) 5520 bytes/sec


So basicly, VoiceCodec=3 is what you want. As for VoiceFormat=#, higher the number, the higher the quality but probably the higher the lag you will get.

Default Private or public?

Is the server hosted by a hosting company or local?
You can change the codecs of the server in the ini file if its a local hosted server. If you pay for a public server you need to contact the server hosting company.
If you are running a server from your PC run the comand prompt nt program then type "ventrilo_srv -?" that will show you the list of possible codecs you can use. Then in the ini file you will need to change the voice codec and voice format.
Basically the default is likely
voice codec 0
voice format 1
change those values to match the ones you want.
Example
voice codec 3
voice format 18
Those are just examples there are many different values you could set and the ventrilo_srv -? command will show you what you can use.
You can also test sound quality before you change the server with the client without signing on by going into the setup and changing the settings and testing.

Awesome thanks! But will this affect the other people who use PC's to connect to the vent server?

try using
Speex 16KHz, 16bit, 9 Qlty

that is what we are using on the test server and is a nice balance of quality and bandwidth.

simliar bandwidth byte transfer as GSM 22Khz
