QExE Tool

Direct and indirect scaling quality evaluation methods for perceptual listening tests in VR environments.

Integrate a questionnaire post-item or post-test to collect subjective participant responses alongside objective ratings.

Configure the entire test session using a single JSON file — define stimuli, methods, and questionnaires without code changes.

Import freely available VST plugins for Ambisonic or object-based spatial audio rendering within the VR scene.

Record user and object pose data at runtime, streamed to a log file for offline analysis.

Include computer-generated imagery or 360-degree video scenes as the visual rendering context for each test item.
