Improving Virtual Sound Source Robustness Using Multiresolution Spectral Analysis and Synthesis

A virtual sound source system based on the principle of active noise control is presented. A solution to the robustness problem inherent to this and other virtual source systems is proposed. This solution exploits acoustical and psychoacoustical factors by employing multiresolution spectral analysis. A new multiresolution transformation method, that is suitable for real-time implementation, is developed for this purpose. Performance improvement is shown by simulation.
