Yes, but I was using stereo 22Khz input. With mono, oggenc lets you use -b 16, which on my test wav actually generated an avg 24kbit file. I had to add -M 16 to force it to generate an avg 16kbit file. Is there an oggenc flag that does what lame's --abr ## flag does? i.e. "I want an output file with this average bitrate". So far -b consistently gives me a bitrate up to 50% higher than what I asked for. Time to move this thread to a vorbis list? Oh wait. I see the CC.
