Directional audio is currently accomplished with per-ear propagation delays and direction-dependent amplitude. Convolution with head-related transfer functions (HRTFs) reportedly provides a stronger sense of direction, at the cost of per-source FFT convolution. A fast FFT implementation will be needed, likely employed via the overlap-save method.
