Since the spacialisation of stereo sounds are not supported please add an import setting that converts stereo files to mono. Also add support for Mp3 and ogg.
Also perhaps you could notify the user when he tries to spacialise stereo sounds, after trying many different things I only found that out in the source code.
Hey bigzer -
Thank you for your input. I will pass this request along to our developers for consideration.

I would like to mention as well that if I have to add 16 full length wave audio tracks this ups the size of my project to around 750MB where as if they were Mp3 files the project would not increase more than 60Mb. This should be the NUMBER 1 reason why Mp3 files should be supported in Unreal Engine.
