Xbox Banks and Bits

If a 48Khz/24bit wav file is added to the Audio Bin and built in an Xbox bank, does it need to first be dithered and set to 16bit?

Would the bank building process handle this?

FMOD will convert from 24bit to 16bit through truncation, not through dithering.

If this is something you require, at the moment you will need to handle this.
