This book gives a broad overview of research on sound simulation driven by a variety of applications. Vibrating objects produce sound, which then propagates through a medium such as air or water before finally being heard by a listener. As a crucial sensory channel, sound plays a vital role in many applications. There is a well-established research community in acoustics that has studied the problems related to sound simulation for six decades. Some of the earliest work was motivated by the design of concert halls, theaters, or lecture rooms with good acoustic characteristics. These problems also have been investigated in other applications, including noise control and sound design for urban planning, building construction, and automotive applications. Moreover, plausible or realistic sound effects can improve the sense of presence in a virtual environment or a game. In these applications, sound can provide important clues such as source directionality and spatial size. The book first surveys various sound synthesis methods, including harmonic synthesis, texture synthesis, spectral analysis, and physics-based synthesis. Next, it provides an overview of sound propagation techniques, including wave-based methods, geometric-based methods, and hybrid methods. The book also summarizes various techniques for sound rendering. Finally, it surveys some recent trends, including the use of machine learning methods to accelerate sound simulation and the use of sound simulation techniques for other applications such as speech recognition, source localization, and computer-aided design.

The real world is full of sounds: a babbling brook winding through a tranquil forest, an agitated shopping cart plugging down a flight of stairs, or a falling piggybank breaking on the ground. Unfortunately virtual worlds simulated by current simulation algorithms are still inherently silent. Sounds are added as afterthoughts, often using "canned sounds" which have little to do with the animated geometry and physics. While recent decades have seen dramatic success of 3D computer animation, our brain still expects a full spectrum of sensations. The lack of realistic sound rendering methods will continue to cripple our ability to enable highly interactive and realistic virtual experiences as computers become faster. This dissertation presents a family of algorithms for procedural sound synthesis for computer animation. These algorithms are built on physics-based simulation methods for computer graphics, simulating both the object vibrations for sound sources and sound propagation in virtual environments. These approaches make it feasible to automatically generate realistic sounds synchronized with animated dynamics. Our first contribution is a physically based algorithm for synthesizing sounds synchronized with brittle fracture animations. Extending time-varying rigid-body sound models, this method first resolves near-audio-rate fracture events using a fast quasistatic elastic stress solver, and then estimates fracture patterns and resulting fracture impulses using an energy-based model. To make it practical for a large number of fracture debris, we exploit human perceptual ambiguity when synthesizing sounds from many objects, and propose to use pre-computed sound proxies for reduced cost of sound-model generation. We then introduce a contact sound model for improved sound quality. This method captures very detailed non-rigid sound phenomena by resolving modal vibrations in both collision and frictional contact processing stages, thereby producing contact sounds with much richer audible details such as micro-collisions and chattering. This algorithm is practical, enabled by a novel asynchronous integrator with model-level adaptivity built into a frictional contact solver. Our third contribution focuses on another major type of sound phenomena, fluid sounds. We propose a practical method for automatic synthesis of bubblebased fluid sounds from fluid animations. This method first acoustically augments existing incompressible fluid solvers with particle-based models for bubble creation, vibration, and advection. To model sound propagation in both fluid and air domain, we weight each single-bubble sound by its bubble-to-ear acoustic transfer function value, which is modeled as a discrete Green's function of the Helmholtz equation. A fast dual-domain multipole boundary-integral solver is introduced for hundreds of thousands of Helmholtz solves in a typical babbling fluid simulation. Finally, we switch gear and present a fast self-collision detection method for deforming triangle meshes. This method can accelerate deformable simulations and lead to faster sound synthesis of deformable phenomena. Inspired by a simple idea that a mesh cannot self collide unless it deforms enough, this method supports arbitrary mesh deformations while still being fast. Given a bounding volume hierarchy (BVH) for a triangle mesh, we operate on bounding-volume-related submeshes, and precompute Energy-based Self- Collision Culling (ESCC) certificates, which indicate the amount of deformation energy required for the submesh to self collide. After updating energy values at runtime, many bounding-volume self-collision queries can be culled using the ESCC certificates. We propose an affine-frame Laplacian-based energy definition which sports a highly optimized certificate preprocess and fast runtime energy evaluation.

Refining Sound is a practical roadmap to the complexities of creating sounds on modern synthesizers. Perhaps the most difficult aspect of learning to create sounds on a synthesizer is understanding what all the individual synthesizer components contribute to the complex finished sound. Author and veteran synthesizer instructor Brian K. Shepard draws on his years of experience in synthesizer pedagogy in order to peel back the often-mysterious layers of sound synthesis one-by-one. The result is a book that allows readers to familiarize themselves with each individual step in the synthesis process, in turn empowering them in their own creative or experimental work. Refining Sound follows the stages of synthesis in chronological progression from the "raw materials" of sound waves through the various stages of the refinement process, ultimately bringing readers to the final "polishing" of their sounds with audio effects. Each chapter focuses on a particular aspect of the synthesis process, and contains easily digestible guided projects (entitled "Your Turn" sections) that focus on the topics of the chapter. Throughout the text, the material is supported by copious examples and illustrations and more than forty interactive synthesis demonstrations on the related companion website that allow the reader to experiment with and understand these concepts without the distraction of other synthesizer controls and modifiers. The final chapter brings everything together as the reader creates several common types of synthesizer sounds with detailed step-by-step instructions and explanations of the concepts behind those steps. With all of the sounds in the final chapter, readers are given suggestions and tips on ways to modify the sounds, with final outcomes left to the readers' own creativity. Refining Sound is essential for all electronic musicians from amateur to professional levels of accomplishment, students, teachers, libraries, and anyone interested in creating sounds on a synthesizer.

Physics-based sound synthesis is an increasingly popular technique in computer graphics to automatically generate realistic sounds associated to (otherwise silent) visual events, such as a spolling green plastic bowl or a dripping faucet. Previous work has shown very promising results; however, these algorithms still suffer from several shortcomings, such as long precomputation time or difficult integration for complex sound sources. In this thesis, we explore new simulation frameworks that leverage time-domain methods and insights to improve both the quality and speed of physics-based sound synthesis algorithms. First, we introduce KleinPAT, a new time-domain algorithm that rapidly estimates acoustic transfer fields of a vibrating rigid object (modeled by the linear modal model). Instead of estimating the transfer fields by (sequentially) solving the frequency-domain Helmholtz equations, our method partitions all vibration modes into chords using optimal mode conflation, performs a single time-domain wave simulation for each chord, and then separates the per-mode transfer fields using a deconflation solver. We show that our method achieves thousand-fold speedup compared to the more traditional fast boundary element methods, and maintains accuracy suitable for sound synthesis. Second, we present an integrated time-domain acoustic wavesolver to support sound rendering of a wide variety of physics-based simulation models and computer animated phenomena. We target high-quality offline rendering, and introduce methods including a sharp-interface boundary handling method, the acoustic shaders abstraction to integrate various sound sources, and a parallel-in-time synthesis algorithm for this task. We demonstrate the generality and quality of the solver by rendering sound sources of dynamic, multi-physics nature, such as vibrating solids, thin shells, water, and character. Finally, we will switch gears and introduce a new method to enrich standard rigid-body impact models with spatially varying coefficient of restitution maps, or Bounce Maps. We demonstrate that the commonly accepted hypothesis of constant restitution value per object is wildly incorrect, and propose a fast precomputation algorithm to sample and compute it. The resulting Bounce Maps can be queried in negligible time and can be used easily to enhance existing solvers. Although it is not directly related to sound synthesis, we will show that a dominant factor for varying restitution responses is the post-impact vibrations, which can cause sound.
