How do I adjust the voice quality?

Theres been some people asking me about ventrilo codecs and adjusting them so here they are as follows:

Code: Select all

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

Login to the control panel and go to 'Easy setup" tab, and edit select the desired codec from the drop down boxed titled "Voice codec type"

I would only use one of the top 3 codecs. NFo's default codec is the 2nd from the top, operating GSM 6.10 (11025 Hz, 16 bit).

*Note: Increasing the sound quality also increases the bandwidth used client side.

The Speex codec was also added in the latest Ventrilo version. Speex is a good codec that generally offers similar quality at lower bitrates than other codecs; however, it is more sensitive to input clipping (when the microphone or volume input settings are inappropriate and the recorded sound is too loud). We recommend that you try different settings for the codec to determine what is best for your particular group of users.
