Abstract. The aim of this paper is to show the development of an immersive application in a historic visual and acoustic space. The “Llotja de la Seda” (“Silk Exchange Building”) is a late Valencian Gothic style civil building in Valencia (Spain), built between 1482 and 1548. The UNESCO considered it as a World Heritage Site in 1996 since “the site is of outstanding universal value as it is a wholly exceptional example of a secular building in late Gothic style, which illustrates the power and wealth of one of the great Mediterranean mercantile cities”.
In this on-going work, we have joined the development of a specific Head Mount Display for our application, in combination with a HRTF rendering system, and the virtual reality and acoustic modelling of this building. The acoustical calibration of the model was made using 25 impulse response measurements according to ISO3382. The Llotja’s reverberation time at mid-frequencies is 3.1 s, with a volume of 12,100 m . From this model we are developing applications for dynamic representa- tion mixing voice and music.
