In this paper, we present low-complexity 3D audio algorithms suitable for applications based on low-power and low-memory hardware. The algorithms include an artificial reverberator associated with a time-varying all-pass filter, IIR crosstalk cancelation filters implementing frequency warping, and a headphone externalization algorithm based on simplified head-related transfer functions (HRTF's). Performances and complexities of the presented algorithms are measured and compared with the conventional ones. 20 30% of memory reduction was gained using the time-varying artificial reverberator, and 50% of computational reduction was achieved using the IIR crosstalk cancellation filters. Finally, 80% of computational complexity and 50% of memory were saved by using the simplified externalization system.
