Abstract
It is well known that sound localisation is heavily dependent on frequency. Band-limited signals generally suffer from poor localisation potential. While significant effort has been invested in HRTF modelling, room acoustics and crosstalk filtering, research into alleviating the spatial system performance dependence on source spectral characteristics has been largely overlooked. The authors briefly consider how one can compensate source frequency-deficient bands that are critical to localisation with wavelet packet decomposition
