The Effect of Electronic Reverberation in a Hybrid Reverberation Enhancement System: CarmenCita

Abstract : Active reverberation systems turn a performance hall with naturally dry acoustics into a multipurpose venue that can host any type of performance from theatre to symphonic music. Different types of active reverberation systems exist. All systems have loudspeakers spread on the walls and ceiling of the audience area, but they differ in two main concepts: the locations where the sound is picked-up and the use of electronic reverberation algorithms or not. ?In-line? systems pick the sound close to the stage, add electronic reverberation and diffuse it in the audience area. ?Regenerative? systems such as Carmen pick the sound in the audience area and increase reverberation in the room without using electronic reverberation algorithms but only amplification and delays. Finally, ?hybrid? systems like CarmenCita pick the sound in the audience area and add reverberation with specifically designed reverberation algorithms. This work investigates the convolution that happens between electronic reverberation and the natural response of a concert hall with a hybrid reverberation enhancement system as CarmenCita. The effect of the system on various acoustic indicators is explained based on measurements performed at Espace Paul Jargot, a 400-seat multipurpose venue located in Crolles, France.
