Spatial location

·   Primary spatial cue is azimuth (from 2 ears)

- L-R intensity difference (head shadow) ~ 1 dB
- L-R envelope delay (path length) ~ 0.1 ms


·   Secondary cues for elevation and range

- elevation from L-R spectrum & its changes
- range from level, coloration, direct-to-reverb


·   Synthesizing spatial location

- simple pan + delay (freq. dep?) for azimuth
- sampled HRTFs can incorporate elevation
  ... depend on individual


·   Delivering spatialized signals

- headphones
- speakers, transaural
- but: listener location?
  dynamic cues?
