An object, beyond its image

A photograph records an appearance. A recording captures a particular sounding event. A three-dimensional model describes geometry. Each makes something about an instrument accessible, but none alone carries the whole research context.

A Virtual Acoustic Object (VAO) connects these representations in an explicit, versioned research object. Descriptive information, recordings, measurements, images, geometry and interaction data can be related to their sources, rights and exact files.

A connection between evidence and experience#

The exchange standard and the experience are separate. A VAO package is a fixed dataset; a viewer or runtime interprets the capabilities it declares. An object can support a spatial model, sampled playback or an analytical view without implying that every package supports every experience.

Follow one note through the object#

Consider a single recorded organ note. To interpret it, a listener needs more than an audio file: which instrument and stop sounded, which key was pressed, when the recording was made, how the microphones were positioned and whether the signal has been edited. A view of the pipe or keyboard adds another perspective, but only an explicit relationship tells the reader whether that geometry belongs to the recorded configuration.

A VAO gives these resources a common, inspectable context. The note can remain connected to its source take; a playback region can identify a selection within that take; a derived model can point to the measurements used to construct it. The experience becomes a route back to the research, rather than the final destination of the data.

What the object connects#

A package can be useful without being complete#

An image-and-audio release can support a well-defined study even if no playable instrument has been built. Likewise, an interactive reconstruction may deliberately explore an earlier configuration rather than document the surviving object. The useful question is what the release claims to represent and what evidence supports that claim. Declared scope lets readers compare unlike packages without mistaking a polished experience for comprehensive documentation.
