The use of wave methods to simulate room impulse responses provides the most accurate solutions. Recently, a method to incorporate directive sources in discrete-time methods, such as Finite Differences and Digital Waveguide Mesh has been proposed. It is based in the proper combination of monopoles in order to achieve the desired directivity pattern in far field condition. However, this method is used without taking into account the inherent dispersion in most of these discrete-time paradigms. This paper analyzes how influent is the dispersion in order to get the proper directivity through different study cases.
