Population spatialization reveals the distribution and quantity of population in geographic space with gridded maps. Fine-scale is essential for urbanization disaster prevention. Previous approaches have used remotely sensed imagery to disaggregate census data, but this approach has limitations. For example, large-scale censuses cannot be conducted underdeveloped countries or regions, remote se...

This paper analyzes post-socialist industrial development and policy in the Western Balkans through lens of its regional specialization spatial concentration. Against a conceptual framework revolving around place-based policy, using Concentration index (modified Herfindahl-Hirschman index) location coefficients (Balassa index), comparative analysis over three decades (1990–2020) highlights weak...

This paper aims at proposing a cognitive structure for discourse deixis, in terms of which deixis is understood and used to structure reality, so that reality is internally experienced and hence reproduced or changed. The paper also tries to argue that discourse deixis is metaphorically derived from place deixis. This analysis is consistent with and confirms the spatialization-of-form hypothesi...

We propose a system for controlling in real time the localisation of sound sources. The system, called MidiSpace, is a real time spatializer of Midi music. We raise the issue of which interface is the most adapted for using MidiSpace. Two interfaces are proposed: a 2D interface for controlling the position of sound sources with a global view of the musical setup, and a 3D/VRML interface for mov...

This paper describes a software demonstration program, implemented in Matlab®, which has been designed to facilitate the teaching of how 3D sound is synthesized using computerized techniques. The demonstration program simplifies the explanation of the fundamentals of 3D sound through interactive visual and auditory examples. As an extension to the Matlab® demonstration program, a real-time impl...

The Klangdom is an audio spatialization instrument developed at the Institut für Musik und Akustik at the ZKM. It is made up of 39 Meyer Sound loudspeakers hung on four sliding tracks, allowing for easy re-configuration of the speaker setup. The audience sits inside the Klangdom, which can be controlled either directly via a mixer, by externally developed software, or by a sequencer for sound m...

In this paper we present a reverberation system based on a multiloudspeaker configuration. The aim of this work is to produce a natural sounding reverberation system with a similar pattern to the produced in real rooms. A new method for sound spatialization is presented, and it is used to locate on the virtual room’s surfaces the early reflections produced in a reverberant space. Each loudspeak...

This work presents an algorithm that is able to achieve novel spatialization effects on multitrack audio signals. It relies on a crossadaptive framework that dynamically maps the azimuth positions of each track’s time-frequency bins with the goal of reducing masking between source signals by dynamically separating them across space. The outputs of this system are compared to traditional panning...
