gzdoom-gles/src/s_sound.h
Randy Heit 03b4f71edf - Reduced the range that area sounds require to interpolate between 2D and
3D panning.
- The listener's velocity is now set at 0 for the sound engine. The player
  moves so fast that you can hear the doppler shift just by running around,
  otherwise.
- Changed the sound code so that all sounds that start playing on a single
  tic actually start playing at the exact same sample position.
