  This paper presents our work to enhance the background music (BGM) in
DareFightingICE by adding adaptive features. The adaptive BGM consists of three
different categories of instruments playing the BGM of the winner sound design
from the 2022 DareFightingICE Competition. The BGM adapts by changing the
volume of each category of instruments. Each category is connected to a
different element of the game. We then run experiments to evaluate the adaptive
BGM by using a deep reinforcement learning AI agent that only uses audio as
input (Blind DL AI). The results show that the performance of the Blind DL AI
improves while playing with the adaptive BGM as compared to playing without the
adaptive BGM.
