AB  - We present a new software application based on a recently collected HRIR database comprising measurements at different distances. The new application, programmed in Pure-data, is capable of directionalizing sound objects at any azimuth, at elevations between -40 degrees and 90 degrees, and at distances 20-160 cm. This truly 3D spatialization is done by pre-calculating the minimum-phase version of the HRIRs and computing the interpolation of a maximum of four HRIR measurements, depending upon the virtual location. In the same way, interaural time differences are computed and applied to the convolved signal. For demanding real-time constraints, the number of taps used for the convolution can be adjusted, up to a maximum of 1024.
