Another key aspect to movement sound is the sound of clothing material as a character travels through the world. Whether it's age-old leather, chain-mail, or plate style armor, the distinguishing characteristics add to the footstep sounds and help bring an additional level of believability. The sound of movement is especially important if different types of wearables can be changed or added during the course of gameplay. Changing out the sound whenever possible helps to reinforce a choice made by the player and adds to the level of realism throughout their experience.
