I'm trying to get the filesize in my game down. I noticed all of the songs are stereo, with a left and right audio track, when I export a mp3, the options I see are 'joint stereo' and 'stereo'. is joint stereo the same as mono? The filesize seems to be the same, I even converted the stereo track to mono and the filesize didn't change. I'm assuming that half samples would mean half the file size.
Am I going about this the wrong way, or with the wrong mentality? Do you have any tips to lower the file size? I've already lowered the quality to 64 kbps.
