Abstract

The paper presents results on spatial audio quality evaluation and approaches for modeling the data using binaural-hearing models, following the interactive and object-related framework developed in the EC-funded FET-Open project TWO!EARS (www.twoears.eu, see also Raake & Blauert QoMEX 2013, Raake et al. Forum Acusticum 2014). Two types of tests and respective modeling approaches are presented: (1) Feature modeling following the well-established approach of spatial and timbral fidelity prediction. To this aim, a feature-specific set of listening tests was conducted for ground-truth data collection. The resulting feature models apply different parts of the bottom-up auditory processing modules from the TWO!EARS framework. (2) Preference modeling. For collecting the underlying data, a listening test series was conducted applying tailored mixes for different musical pieces with different variations of the mixing choices for specific sources in the scene. Using a full paired-comparison test paradigm, preference ratings were collected from listeners. The respective model involves TWO!EARS’ scene segregation for object identification and subsequent object-specific feature extraction.
