AB  - This paper covers the construction and validation of an affordable and accurate two degree-of-freedom rotational mount for making HRTF (head-related transfer function) and BRIR (binaural room impulse response) measurements using a dummy head microphone. We review the design requirements for a rotational mount in the context of measurements for binaural rendering, with reference to perceptual factors. In order to achieve a low-cost solution, we evaluate the suitability of a motorized telescope mount. Issues considered during design of the system are discussed. The use of affordable electronics to convert the mount into a general-purpose computer-controlled rotational platform is presented, as well as objective measurements to validate performance. Finally the limitations of this system are discussed and further use cases proposed.
