In this research, the idea of a “holographic sound recording” or HSR is explored to support applications where multi-directional radiation characteristics can be implemented to emulate a real sound source. We choose the term “holographic” due to its uncanny ability to create a realistic 3D sound source in a virtual acoustic space, similar to holographic visual experiences. Important factors such as acoustical points of interest, adequate number of microphones, pickup patterns and angles are explored, as well as capturing room acoustics and the benefits of player isolation. Specific recording techniques are introduced that can be used to create a holographic miking system called the Multi-timbral Hologram Array (MtH: pronounced “myth”) as a starting point for recordists who wish to create a holographic reproduction of a real sound source. The MtH Array can theoretically be fine-tuned and customized to help capture complex radiation characteristics of any acoustic instrument. An online companion links with extensive documentation in the medium of photos and playable files are included in the “Examples” section of the paper.
