Abstract

The dedicated audio rendering engine for conducting listening experiments using the SALTE (Spatial Audio Listening Test Environment) open-source virtual reality framework is presented. The renderer can be used for controlled playback of Ambisonic scenes (up to 7th order) over headphones and loudspeakers. Binaural-based Ambisonic rendering facilitates the use of custom HRIRs contained within separate WAV files or SOFA files as well as head tracking. All parameters of the audio rendering software can be controlled in real-time by the SALTE graphical user interface. This allows for perceptual evaluation of Ambisonic scenes and different decoding schemes using custom HRTFs.
