This paper presents SALTE (Spatial Audio Listening Test Environment), an open-source framework for creating spatial audio perceptual testing within virtual reality (VR). The framework incorporates standard test paradigms such as MUSHRA, 3GPP TS 26.259 and audio localization. The simplified drag-and-drop user interface facilitates rapid and robust construction of customized VR experimental environments within Unity3D without any prior knowledge of the game engine or the C# coding language. All audio is rendered by the dedicated SALTE audio renderer which is controlled by dynamic participant data sent via Open Sound Control (OSC). Finally, the software is capable of exporting all experimental conditions such as visuals, participant interaction mechanisms, and test parameters allowing for streamlined and standardized comparable data within and in-between organizations.
