the voice-communication TeamSpeak (www.teamspeak.org) is currently testing a
version that supports speex codecs. The quality for high bitrates is quite
BUT, the low-bandwidth speex codecs that are currently used arent very good.
What I did to find this out:
I comprared a speex AVB with 6.3 KBit/sec (total, overhead for packets and
stuff included) and the 6.3 Kbit/sec Celp Codec vom hawkvoice (
http://www.hawksoft.com/hawkvoice) and the result is quite favorable for
I cant believe that this is *normal* speex behavior, please correct me if that
hawkvoice thing just performs better on that bandwidth.
Now for my question:
Could you please tell me what options are best for what codec bandwidth ? Im
figuring something is wrong since speex sounds worse than hawkvoice on the
low bandwidth...I would appreciate if youd post the *recommended* settings
for 5, 10, 15 and 20 KBit narrowband AVB speex (used in a voicecom that
shouldnt take too many cpu cylces of the game).
Please excuse my bad english and thanks in advance for helping
Many people are unenthusiastic about their work.
