Per OpenAL docs, 3D POSITIONAL AUDIO emits sound from a source with which feature set?
AOnly a fixed echo curve regardless of distance
BPosition + velocity used to pan + Doppler-shift the sound
COnly stereo phase reversal regardless of position
DOnly volume scaling by distance is supported
Answer & Solution
Correct answer: B. Position + velocity used to pan + Doppler-shift the sound
OpenAL spec: each source has position + velocity; the listener also has these. Engine computes panning, attenuation, and Doppler shift.
