speex voice seems to be bit breaking over long distance.
...breaking portion is filled with previous packet. This trick seems to work so far. I am not sure what is the side effect. I think jitter buffering is more correct way to solve this problem but I think this is not so easy. Is there got any source code to reference from?

Otherwise, if you're aware of another mechanism that allows it to allocate temporary stuff on the stack, I might be able to support it. Jean-Marc > -----Oorspronkelij...

Echo canceller: residue value
...floats to the pointer. I find this plus one strange, since almost all things are exactly the framesize. Is this an error in the echo_cancel function or simply an exception? Maybe you should define in the manual what exactly the residue is, meaning a float array of which size? Greetings Jeroen de Kleijn

interpolation of lost frames
...on is if it's harmfull for the audioquality that at the end of the talkspurt one frame is interpolated? Or would this be almost inpossible to hear since the last audiopacket in the talkspurt already is about silent? This obviously depends on how speex interpolates a frame.

speex 1.1.8
Hi, I saw there is a new release of speex. What is this SPEEX_PLC_TUNING option for? And is there a more complete list of changes? Because I like to determine if it is interesting to update to 1.1.8 Greetings Jeroen de Kleijn (developer of VoIPerized)

Speex 1.0.5 and 1.1.8 are out!
Hi everyone, As many noticed, I just released 1.0.5 and 1.1.8 over the weekend. There isn't much new in 1.0.5, except that I added all the API changes from 1.1.x so that it's possible to write code that will work with both 1.0.5 and 1.1.8. As for 1.1.8, here are the changes: - Initial TI C5x port: I integrated a patch from Jamey Hicks - Some fixed-point improvements and fixes - Better

stuttering in speex 1.1.11
...ersions of Speex I was wondering if one of the bug fixes in 1.1.12 solves a bug which causes the stuttering. To me the stuttering report sounds like the decoder state that speex uses gets messed up. Some info, I use the floating point version of Speex 1.1.11 both SSE/non-SSE. Greetings Jeroen de Kleijn

setting SSE at runtime (speex_set_asm)
...tion called speex_set_asm. I have been searching the archives, but I could not found that specific post. I noticed the new 1.2beta1 does not include this patch, so I was curious if the person who originally made this patch has made the same modifications to the new 1.2beta1. Greetings Jeroen de Kleijn
