In the default mode of operation, the quality level is 3\&. Normal quality range is 0 \- 10\&. .RE .PP managed .RS 4 Boolean\&. 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 can be slower, and may also be lower quality\&. It is primarily useful for streaming\&. .RE .PP max_bit_rate .RS 4 Enabled only if managed is TRUE .RE .PP min_bit_rate .RS 4 Enabled only if managed is TRUE .RE .PP downmix .RS 4 Boolean\&. Downmix input from stereo to mono (has no effect on non\-stereo streams)\&. Useful for lower\-bitrate encoding\&. .RE .SH "DESCRIPTION" .PP These options were extracted from the OpenMAX IL spec and Gstreamer vorbisenc properties .PP For best quality users should specify VBR mode and set quality levels\&. .SH "COPYRIGHT" .br
