Abstract This bachelor thesis presents a detailed overview of the acquisition and storage of head-related transfer functions (HRTFs) and similar directional audio data, providing both theoretical basics and an examination of publicly available datasets and databases. The need for more and larger high-quality HRTF databases is mainly addressed in two ways: Firstly, knowledge is established, which allows to assess and enhance the quality of existing or future databases in terms of spatial resolution, optimization of the measurement process, choice of the impulse response measurement method and post-processing. Secondly, particular focus is laid on the possible creation of a standardized directional audio storage format. For sake of more universal applications of such a format, the scope is extended from HRTFs to general head-related directional audio data.
