Dynamic Sound Effect Based on Distance of Interactive Object using Linear Interpolation Method in Unity3D

Sound effect is one of the important component in a game. It can express a moment or an action at a certain time in the game and emphasize the visual experience of what the player see. Thus, it can increase the immersive feeling for the player. While creating each sound effects by recording them separately is possible, it can be time consuming and very inefficient to complete. Therefore, creating a dynamic sound effect is needed to cut down on the production time and complete the game quicker. Our prototype specifically created for interactive object that can be picked up or placed by the player. It produces sound effect based on the distance of the player and the object. We use loudness and pitch as our control variables to produce a dynamic sound effect. Those variables are controlled using linear interpolation(Lerp) method, so it produces sound based on the determined graphic.
