If I understand your question properly, you need read the floating point data for each sample, sum them, and write the resulting value into your new audio stream. This would give a stright 50/50 mix.

I don't have access to a machine with a compiler right now, but it should be something like this (assuming bytes1 and bytes2 are two ByteArray objects of equal length):

for (int bcnt = bytes1.size(); bcnt; bcnt--)
    bytes1.setByte(bcnt - 1, bytes2.getByte(bcnt - 1) + bytes1.getByte(bcnt - 1));

Of course, you would probably want to do some sort of overflow check, but that should be enough to put you on the right track.
