About This File
A direct port of my most downloaded modification for Grand Theft Auto IV, the Federal Signal Touchmaster Delta siren.
Sweep/Scan tone (separate file)
Due to limitations with the game, this siren does NOT replace the FIB, Granger, Ambulance or Firetruck sirens. I apologize for this, but there's nothing I can do without trimming down and ruining the original audio files.
