• 3D sound (Halo, Grand Theft Auto San Andreas and every game with
  positional effects and voices): muffled, smeared and too quiet. The
  console's HRTF filters, the head-related responses DirectSound loads
  for 3D voices, come as sign-and-magnitude bytes; they were read as two's
  complement, so a small negative tap (0x81, -1) became -127 and each
  response turned to noise across its 31 taps. Each was then divided by
  the sum of its taps' sizes, which left 3D voices 8 to 10 dB under the
  rest of the mix (dialogue among them). The taps are read as the
  hardware reads them and weighed as it does: the frontal response passes
  speech at about unity, and the sides show the head's shadow and the
  ear's resonance as they should. Savestates from before are converted as
  they load.
