Algorithmic spatialization places sounds in virtual acoustic space using channel-based diffusion, object-based rendering (VBAP/Ambisonics/WFS), or binaural techniques

Spatialization is the act of placing sounds in a virtual or real acoustic space, or creating/manipulating a sound space. Channel-based diffusion routes sound directly to specific speakers. Object-based rendering abstracts sound as objects with positions, then renders to any speaker configuration: VBAP (Vector Base Amplitude Panning) for efficient multichannel positioning; Ambisonics for full-sphere 3D with scalable angular resolution (order determines precision); Wave Field Synthesis for physically accurate wavefronts. Binaural rendering produces 3D audio for headphones using HRTFs. Parameters of these algorithms (e.g., VBAP spread factor, Ambisonics order) can become compositional parameters.

Examples

A generative patch that randomly moves sound objects through 8-channel space using VBAP: positions are controlled algorithmically, creating spatial patterns as a compositional dimension.

Assessment

Name and briefly describe three different spatialization techniques. For each, describe a musical context where it would be the best choice and one where it would be inappropriate.
