5.3 Zip Format

This file format represents a compound information such as a transfer function file for localization which represents transfer functions for all directions. A transfer function includes multiple kinds of information, for example, microphone positions, source positions, and transfer functions themselves. Thiz zip format combines all of them into single file, and represents their relationship with a directory tree.

Although Zip Format can represent arbitrary kinds of information structure, we currently support only one structure as libharkio3 API. We use the structure for a transfer function, a separation matrix, and a correlation matrix.
