Multipurpose auditoria demand variable reverberation which can be accomplished using electroacoustic systems. In order to minimize the complexity of such a system, the control of perceptually redundant information should be avoided. Therefore, the design of such a system should be based on perceptually relevant parameters. It was found that modification of the auditorium`s spectral energy decay curve is sufficient to control the temporal properties of the reverberant sound field. The paper describes a proposal to implement this modification by plane wave synthesis from a limited number of directions, thus generating a reverberant sound field with variable diffusiveness.
