Example‐based synthesis for sound of ocean waves caused by bubble dynamics

Water sound synthesis has attracted more and more attention in the recent years. Most current methods generate realistic water sounds based on simulation of bubble dynamics. However, for a large-scale dynamic water scene, this type of simulation is prohibitively expensive. This paper proposes a new approach to generate sound caused by bubble dynamics for ocean waves. In addition, the synthesis method is based on sound examples. The sound synthesis process includes the following steps: bubble particle extraction, wave attribute generation, and an example-based sound synthesis process. We propose a grid-based clustering method to improve the efficiency of our algorithm so that we can synthesize sound in real time. We also exploit a mapping method to properly generate the ocean sound according to the wave attributes. Various experiments demonstrated that our method can achieve competitive sounding results for ocean waves in terms of sound quality. REFERENCE 1. Wang K, Liu S.
