Lower audio bitrate for steaming

I need help with lowering the audio bitrate that the MediaBrowser is streaming. I can't seem to find the correct field nor do I know which profile I am supposed to edit.
If I could lower the bitrate on all the songs that are streamed through MediaBrowser then I'd be golden!

The bit rate is set by the streaming server. You cannot lower it. You can of course transcode it after you receive it but what would be the point.

I mean't that I have the music on my server and I am listening to it through the internet using the MediaBrowser. Is there somewhere on the server's config files where I can change the audio bitrate to be lower because my internet upload speed is really low...

Find the profile called flv_player (right at the top) and replace

<Audio targetContainer="mp3">
                <Matches container="mp4" />
                <Matches container="flac" />
                <Matches container="ogg" />
                <Matches container="lpcm" />
                <Matches container="adts" />
                <Matches container="asf" />
                <Matches container="wavpack" />
                <Matches container="mpc" />
                <Matches container="ape" />
</Audio>


with

  Code:

<Audio targetContainer="mp3" aBitrate="64">
                <Matches container="*" />
