Sound recording from spatially extended sources is an interesting acoustical problem that only in recent years, thanks to the advent of multichannel audio, has started to be successfully dealt with. In this respect the choral music is indeed a challenging audio test-bed both in the recording and playback phase of sound reproduction technology. Acoustic Quadraphony (AQ) has been applied to render the sound of a choir of about thirty singers in the classical 4 voices composition (Basso-Tenore-Contralto-Soprano) in a church. Starting with pseudo-anechoic signals corresponding to each voice and Quadraphonic Impulse Responses, a multiple quad-convolution process has been performed and then the final spatially and temporally superimposed quadsignals are reproduced through a common 5.1 surround system.
