IR is a record file of dynamic changes of sound in a space. 

Simply with an IR file, a creator can simulate the sound of music in a specific space.

The green line of Taichung MRT runs on Wenxin Road, a dense commercial area with many buildings on both sides. Therefore, we provide IR files for 10 stations from Sihwei Elementary School station (105) to Fengle Park station (114) for creators to simulate how the music sounds when played at the stations, and further adjust so that their musical compositions can better fit the stations.
