I've adjusted some volumes and distance radii. It's not the final version but its an improvement. It will make the taunts/warcries louder and able to hear from a further distance. Download and install V1.0 then install new text files (v1.1) into your Rome/data folder and say "yes" to replace all existing files. For more info see thread:
