Wavelet packet decomposition for spatial sound conditioning

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