I tried using SMplayer and VLC under both Linux and Windows and MPC-HC and MediaInfo under Windows. None of them will show me the bitrate for AAC audio streams when in an MKV container. I'm assuming this is because it was encoded using a variable bitrate? There has to be a way to get the average bitrate though because all the torrents on Baka that I have checked have a bitrate listed for AAC.

Is there a nice software solution that will tell me this? I'm pretty sure there is a mathematical formula for calculating this but I hate math >:(

I think they find the bitrate by sum random geek way xD

Could you extract the audio track then use an audio player to find out. I know that foobar2k will do that.

Foobar has a plugin to read mkv, just drop the whole video in and it should do just fine.

Nice! Under the audio properties it seems to want to list the entire bitrate but I know my video bitrate so I just subtract it from the total and I get my answer. I've used foobar2000 in the past but never realized it could handle .mkv files.

What's really awesome is the latest version seems to work pretty well under WINE!

Thanks alot!
