Generating realistic sounds for soft bodies is a challenging task due to the complexity of the interactions. Therefore, automatic audio generation based on procedural approach has become an attractive method for digital synthesis of soft-body sounds. In this paper, we present a comprehensive review in the field of procedural audio, with a special focus on synthesizing the sound of soft bodies. We first introduce the concept of procedural sound generation, including its advantages and challenges for soft-body sound synthesis. Next, we review the state-of-the-art in rigid/non-rigid-body sound synthesis techniques for computer animations and games. Thirdly, we summarize and survey a taxonomy of existing synthesis methods from previous literatures by analyzing their benefits and drawbacks for generating soft-body sounds. These methods include modal synthesis, sound texture modeling, motion-driven sound synthesis, wavelet tree learning, granular synthesis, and concatenative sound synthesis. Last but not least, we discuss several possible directions for future research in procedural soft-body sound synthesis.
