...andwidth VBR will output. I thought getting the bitrate just after setting the vbr quality was the maximum, but this seems to be just a good guess of the average. .. Unfortunately, and a bit unexpectedly, the same is true for ABR. If you have a loooong period of silence in the beginning, st->vbr_quality will slowly increase. If you then have lots of talking, st->vbr_quality decreases very very slowly as st->abr_count is now very high. The end result is that the target bitrate is exceeded quite drastically over short time periods. As the limit is there to keep the network bandwidth from...

...onstant bitrate and set it using quality parameter - SPEEX_SET_QUALITY - vbr_bitrate - use variable bitrate and set it using bitrate parameter - SPEEX_SET_BITRATE + SPEEX_SET_VBR - vbr_mode - use variable bitrate and set it using mode parameter - SPEEX_SET_MODE + SPEEX_SET_VBR - vbr_quality - use variable bitrate and set it using quality parameter - SPEEX_SET_VBR_QUALITY If I look at the code, vbr_bitrate and vbr_mode probably doens't work (vbr uses vbr_quality and this is only initialized when using SPEEX_SET_ABR or SPEEX_SET_VBR_QUALITY). I have also been looking at dra...

Other options? 16khz (wideband) VBR (VAD and DTX off), passed through preprocessor (VAD, DENOISE, AGC and DEREVERB. AGC level set to 20000). VBR_QUALITY and COMPLEXITY are userconfigurable, I'll ask and see what he's set them to. I must admit I'm a bit stumped as to why it's just this one user that has this problem :( I've been completely unable to replicate the problem here. I've added stackframe output on crashes to th...

...e invalid. I did this based on reading through the speex manual etc. and the recent thread on --dtx etc. Easiest is if you can build and play with that tarball, but I'll at least try to describe the behaviour here. Please let me know where my understanding falls apart :) first up, quality and vbr_quality are mutually exclusive, so instead I'm just providing one slider, which goes from 1 to 10. when vbr is checked, the slider quietly gains a decimal point of precision, giving floating point values, and when vbr is turned off, it reverts to integer values. then, it seems that cbr bitrate and abr...
