From man oggenc:
<quote>
--managed
Set bitrate management mode. This turns off the normal VBR
encoding, but allows hard or soft bitrate constraints to be
enforced by the encoder. This mode is much slower, and may also
be lower quality. It is primarily useful for creating files for
streaming.
Specifying a maximum and average bitrate, and enforcing these.
oggenc infile.wav --managed -b 128 -M 160 out.ogg
