Mozarabic Chant anechoic recordings for auralization purposes

The Hispanic Rite is the liturgy celebrated by Christians of the Iberian Peninsula before the imposition of the Roman Rite in the mid-eleventh century. As in other early Christian liturgies, music was the core of the Hispanic Rite. This music, known as Mozarabic Chant is one of the richest musical repertoires of the Middle Ages. Currently, a research project is underway involving the restoration of the Hispanic Rite sound, using techniques of acoustic virtual reality. The project aims to perform the auralization of the sound of Mozarabic Chant in his primitive environment, that is, taking into account the acoustic characteristics of the pre-Romanesque churches in their original state. For this purpose, anechoic recordings were made for a number of musical pieces representative of the Mozarabic Chant repertoire. In total eight (8) musical pieces have been recorded and interpreted, each of one, by six (6) different singers. The recordings were made using a spherical array composed by 32 microphones. This paper describes the more relevant aspects related to the recorded musical material, the technical specifications and installation details of the recording equipment, the data processing, and a summary of the results.
