Physically Based Rendered Audio Shaders Collection<\/strong><\/h1>\n\n\n\n
<\/div>\n\n\n\n

The pbrAudioShaders<\/em><\/strong> is the core synthesis engine of the pbrAudioRender framework. It is a curated collection of physically based audio shaders designed to breathe life into your 3D animations by generating sound directly from simulation events. Just as a PBR material defines how light interacts with a surface, a pbrAudio shader defines how a physical interaction becomes sound. Whether it\u2019s a rigidbody colliding, a thin-shell vibrating, a fluid splashing, or a fracture splintering, these shaders translate the physics of your scene into rich, unique, non-repeating realistic audio.<\/p>\n\n\n\n

Why pbrAudioShaders<\/em><\/strong><\/em><\/strong>?<\/h1>\n\n\n\n

The pbrAudioShaders<\/em><\/strong> project is not a black box. The pbrAudioShaders project is open-source and ready to be integrated into your workflow. <\/p>\n\n\n\n

<\/div>\n\n\n\n

\n

Each pbrAudioShaders<\/em><\/strong> is a modular, data-driven engine that listens for specific event types (collision, fracture, aeolian, explosion, …) and object types (rigidbody, fluid, thin-shell, …). <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

The pbrAudioShaders<\/em><\/strong> engines use physically based synthesis and noise model to produce the final audio that enhances dynamics and realism of animations.<\/p>\n<\/div>\n\n\n\n

Key Features<\/h1>\n\n\n\n

Physically Plausible<\/em>: Every sound is a direct consequence of the simulation data not a pre-recorded samples.

Event-Driven<\/em>: Seamlessly integrates with the pbrAudioRender pipeline, reacting to collisions, constraints, and destruction.<\/p>\n\n\n\n

Material-Aware<\/em>: Define acoustic properties (damping, stiffness, density) just like you define roughness or metallicness in a visual shader.<\/p>\n\n\n\n
