AB  - The synthesis of an arbitrary enclosures room impulse response (RIR) may be performed using acoustic modelling. A number of acoustic modelling methods have been proposed previously each with their own advantages and limitations. This paper is concerned with mixing the RIRs from different modelling methods to synthesise a hybrid RIR. Low frequencies are modelled using the finite difference time domain method (FDTD), high frequencies are treated with geometric methods. A practical implementation for forming a hybrid RIR is discussed and further demonstrated in the context of a 2nd order B-Format spatial encode of the modelled sound field. The paper discusses the considerations and limitations of forming such hybrid RIRs using wave-based and geometric-based methods.
