IPEM – Institute for Psychoacoustics and Electronic Music

“IPEM’S HISTORY: IPEM was founded in 1963, as a joint venture between the Belgian Radio and Television broadcasting company (BRT) and Ghent University. The idea was to combine audio engineering with music production, thus building a bridge between scientific research and artistic research. The institute was first located in the electronics laboratory of Prof. H. dr. ir. Vuylsteke, but soon after it was associated with the department of musicology, which was lead by Prof. dr. J.L. Broeckx and later on by Prof. dr. H. Sabbe. Together with ir. W. Landrieu, they developed the institute into a music studio and a center for the study of contemporary music. Music production at IPEM was lead by the composers L. De Meester, K. Goeyvaerts and L. Goethals, all employed by the BRT. They realized many compositions and radio transmissions related to contemporary music. Since 1968, research results at IPEM were published in yearbooks. In collaboration with Sonology (then at Utrecht), this resulted in 1972 in an international journal, called Interface.”
