Editing Variable bitrate (section)

===Bitrate range===
This VBR encoding method allows the user to specify a bitrate range — a minimum and/or maximum allowed bitrate.<ref name="hydrogen-VBR">{{Citation |title=Variable Bitrate |url=http://wiki.hydrogenaud.io/index.php?title=Variable_Bitrate |year=2007 |publisher=Hydrogenaudio |format=knowledgebase |access-date=2009-10-04 |archive-date=2014-07-06 |archive-url=https://web.archive.org/web/20140706173840/http://wiki.hydrogenaud.io/index.php?title=Variable_Bitrate |url-status=live }}</ref> Some encoders extend this method with an average bitrate. The minimum and maximum allowed bitrate set bounds in which the bitrate may vary. The disadvantage of this method is that the average bitrate (and hence file size) will not be known ahead of time.  The bitrate range is also used in some fixed quality encoding methods, but usually without permission to change a particular bitrate.<ref name="hydrogen-LAME-VBR">{{Citation |title=LAME — VBR |url=http://wiki.hydrogenaud.io/index.php?title=LAME#VBR_.28variable_bitrate.29_settings |year=2007 |publisher=Hydrogenaudio |format=knowledgebase |access-date=2009-10-04 |archive-date=2014-06-06 |archive-url=https://web.archive.org/web/20140606173223/http://wiki.hydrogenaud.io/index.php?title=LAME#VBR_.28variable_bitrate.29_settings |url-status=live }}</ref>
