New Csound Opcodes for Binaural Processing

Although solutions to the challenge of binaural artificial recreation of audio spatialisation exist in the Computer Music domain, a review of the area suggests that a comprehensive, generic, accurate and efficient toolset is required. A number of Csound opcodes, using a Head Related Transfer Function based approach, are presented to satisfy this necessity. The process is a complex one, with perhaps the most significant difficulty being phase interpolation. Novel approaches (specifically methods using phase truncation and functionally derived itd respectively), as well as a method based on established digital signal processing methods (minimum phase plus delay) are implemented.
