Speex and G729
[i=s] 本帖最後由 角色 於 2010-5-17 07:35 編輯 [/i]在使用eyeBeam过程中，我发现在上载速度不太好的情况下，系统会选择Speex，而不是G729。看来Speex是比G729更加适合，不知道iLBC又怎样呢？

[b]iLBC is designed for narrow band speech[/b] and results in a payload bit rate of 13.33 kbit/s with an encoding frame length of 30 ms and 15.20 kbps with an encoding length of 20 ms. The [b]iLBC codec enables graceful speech quality degradation [/b]in the case of lost frames, which occurs in connection with lost or delayed IP packets.
[b]iLBC's basic quality higher then G.729A, high robustness to packet loss[/b]
iLBC is [b]Royalty Free Codec [/b]
[attach]56[/attach] 因为我的NAS or IP01系统没有iLBC，所以iLBC是怎样就不知道。
如果bandwidth够，用哪一个codec都可以。
