This letter synthesizes musical instrument directivities by sequentially rotating a loudspeaker through multiple orientations. The synthesis is conducted in a spherical harmonic domain using the actual measured directivity of a commercial loudspeaker and an open database of musical instrument directivities. The letter further proposes a practically useful set of 26 loudspeaker orientations named Step45, which can be used to reproduce the target directivity as well as if the orientations were determined adopting mathematical methods that give equilibrium configurations.
