User-defined spectral manipulation of HRTF for improved localisation in 3D sound systems

摘要

Front-back and elevation confusions typically occur when non-individualised HRTFs (head related transfer functions) are used in a 3D sound system. A practical strategy is proposed to allow more 'customisation' of the 3D sound system. Thus it envisioned that the performance of the basic 3D sound system would be enhanced with the flexibility of user-defined adjustments without the actual measurement of an individual's HRTF.
