We describe how a practical personalized Head-Related Transfer Function (HRTF ) acquisition can be built. It relies heavily on off-loading the computational parts to servers using Processing as a service (PaaS) and Software as a Service (SaaS) methodology. After one has a good quality model of the head geometry, the next step is a simulation running over the audio range. The boundary element simulation is set up to run in the server side, providing an easily configurable access for HRFT calculations over the internet. The last part is the creation of the HRTF filters that can be used for auralization. As an example of the process, we are using a simple geometry based on B&K head and torso simulator (HATS) to show how a dense set of directions and distances are calculated. We briefly discuss the features of the simulated HRTFs, especially, how short distances are quantitatively different from the far field.
