Soundscape Reproduction for Qualitative Assessment
* Präsentierender Autor
Zusammenfassung:The increasing availability of multi-channel microphone arrays, appropriate production tools as well as publishing platforms and formats simplifies the recording, production and reproduction of spatial sound fields and thus opens up novel fields of application for immersive audio. Besides the usage in music, arts and entertainment, immersive audio production is capable to contribute to many other application areas, for example to the conceptual field of soundscapes. A Soundscape is a construct of sound sources within an acoustic environment as well as an embedded context and including the human perception and thus combines physical, psychophysical and emotional components. It can exist as part of a situational and fugitive reality or as reproducible, technical representation of a real or virtual scenario, which can be utilized as reliable stimulus for perceptual assessment. Due to the multidimensional character of soundscapes, the recording, processing and reproduction is challenging in that way, that relevant perceptual properties have to be maintained during the whole processing chain. This lecture introduces the main concept of soundscapes with regard to the technical procedure of recording, processing and reproduction, including binaural reproduction via headphones and sound field reproduction with loudspeakers. It is embedded in general psychophysical considerations of situational sound perception and proposes current research strategies on this topic.
