can someone please explain to me why the presets in nero aac produce higher bitrates than stated. for instance, the vbr streaming preset (100-120kb/s) almost always produces bitrates around 156kb/s. the same thing goes with other presets. what am i missing here?
The bitrates listed in the preset drop down box were calculated for a much older version of the codec. At that time they were accurate. Now the codec has changed significantly and the values should be recalculated.
To add to the previous post, see this (http://www.hydrogenaudio.org/forums/index.php?showtopic=18575&hl=bitrate+inflation) thread.
