The early years of digital sound synthesis were filled with promise following Max Mathews’ publication in 1963 of his pioneering work at Bell Telephone Laboratories [1]. The digital control of loudspeakers allowed for the production of any conceivable sound given the correct sequence of numbers (samples). Producing the correct sequence of numbers, however, turned out to be a formidable task. Ac...

In applications of sonification, the information inferred by the sonification strategy applied often supersedes the amount of information which can be retrieved by the ear about the object of sonification. This paper focuses on the representation of complex geometric formation through sound, drawing on the development of an interactive installation sonifying escape time fractals as an example. ...

Abstract This study analyses one of the most popular game engines and an audio middleware to reproduce sound according propagation physics. The analysis focuses on transmission path between source receiver. Even if there are several ready-to-use real-time auralization platforms software, engines' use with this aim is a recent area for acousticians. However, design needs limits their basic relea...

Laughing while speaking, also referred to as speech-laugh, occurs frequently in social conversations. In order to understand how laughter influences the acoustics of its co-occurring speech signal, we take a synthesis approach in designing an interactive system for artificial “laughter modulation”: users input an arbitrary speech signal, and the system processes the signal to yield acoustic pat...

The Audio Arts and Acoustics department at Columbia College in Chicago acquired a new building in 2003. The facility, a former bank, contained an old steel and concrete vault that was converted to a reverberation chamber. The acoustic properties of the space, including reverberation time, modal density, and early reflection maps were analyzed and compared to a computer model. Reflectograms were...

We consider the Gaussian framework for reverberant audio source separation, where the sources are modeled in the time-frequency domain by their short-term power spectra and their spatial covariance matrices. We propose two alternative probabilistic priors over the spatial covariance matrices which are consistent with the theory of statistical room acoustics and we derive expectation-maximizatio...

This paper is concerned with the definition and description of the phenomenon Off−Talk in human−machine− interaction. This phenomenon is considered to cause problems due to non−relevant information that is conveyed within these utterances. Besides the definition of Off−Talk our work aims to provide an analysis of transcribed audio data that is part of the SmartKom data collection. In the search...

The functional transformationmethod (FTM) is a well-establishedmathematical method for accurate simulations of multidimensional physical systems from various fields of science, including optics, heat andmass transfer, electrical engineering, and acoustics. This paper applies the FTM to real-time simulations of transversal vibrating strings. First, a physical model of a transversal vibrating los...

This paper presents recent developments of the EVERTims project, an auralization framework for virtual acoustics and real-time room acoustic simulation. The EVERTims framework relies on three independent components: a scene graph editor, a room acoustic modeler, and a spatial audio renderer for auralization. The framework was first published and detailed in [1, 2]. Recent developments presented...
