Title:

Energy Aware Modelling of Inter-Aural Level Difference Distortion Impact on Spatial Audio Perception

Authors:

Pablo Delgado (Fraunhofer IIS), Jürgen Herre (Fraunhofer IIS), Armin Taghipour (Fraunhofer), and Nadja Schinkel-Bielefeld (Fraunhofer)

Abstract:

In spatial audio processing, Inter-aural Level Difference Distortions (ILDD) between reference and coded signals play an important role in the perception of quality. To reduce costs, algorithms that predict the perceptual quality of multichannel/spatial audio processing without requiring extensive listening tests are developed. The correct modelling of the perceived ILDD greatly influences the prediction performance. We propose a model of ILDD perception including an energy dependency in different spectral regions of the signal. Model parameters are fitted to subjective results obtained from listening test data over a synthetic audio database with arbitrarily induced ILDD at different intensities, frequencies and energy levels. Finally, we compare our model performance over two databases of real coded signals with two state-of-the-art ILDD models.

Title:

An Approach for Object-Based Spatial Audio Mastering

Authors:

Simon Hestermann (Fraunhofer IDMT), Mario Seideneck (Fraunhofer IDMT), and Christoph Sladeczek (Fraunhofer IDMT)

Abstract:

Object-based spatial audio is an approach for interactive three-dimensional audio reproduction. This concept not only changes the way how content creators interact with the audio, but also changes how it is saved and transmitted. Hence, a new process in the reproduction chain called rendering has to be established. The rendering process generates loudspeaker signals out of an object-based scene. Although recording and mixing have been subject to research in the last years, concepts for object-based mastering are nearly missing. The main difference compared to channel-based mastering is that instead of adjusting loudspeaker channels, audio objects need to be altered. This requires a fundamentally new concept for mastering. In the paper, a new method for mastering of object-based audio is presented.
