Speex dev - Aug 2007 - vbr questions

Hello,

      I am working on a real-time app for embedded hardware. I have two
questions about the variable bit-rate option:

1. Can one designate a maximum bit-rate with the VBR option?
2. Does VBR chunk the bit-rate up and down, i.e. what is the
granularity/speed of the changes in the bit-rate and can that granularity be
defined and/or defined on the fly?

Thanks so much for your help.

Yes, use SPEEX_SET_VBR_MAX_BITRATE, which has been added in 1.2beta2

VBR means the bit-rate can change in any way, at any time. If you want
to change that, you need to dig in the code, thought I don't really see
why you want VBR *and* prevent rapid changes in bit-rate.
