Hi there (from speex-dev newbie), Is it possible to change the target VBR on the fly? The application is a virtual world with multiple media types (voice, video, 3d interaction, VNC, etc.) where the total required bandwidth has high variability. Sometimes we'll be able to spare 30kbps per speaker, and and other times we will need to restrict the bandwidth considerably. It would be a shame to always make the worst-case assumption, even though the bandwidth might usually be available. I was going to ask if there are any other speech codecs (commercial or otherwise) that support this capability, but I guess not since Speex is the only one that supports VBR (according to http://speex.org/comparison/) . Right? Thanks, Josh
