 There are two sound envelopes defined in Aviator.

   * Envelope 1 defines the engine sound. The third, fourth and fifth values
     (envelopeData+2, envelopeData+3 and envelopeData+4) control the choppiness
     of the engine sound and get altered by the MakeEngineSound routine,
     depending on the thrust and airspeed. These values control the change of
     pitch per step in the three stages of the sound envelope, so higher values
     make the sound jump up and down more in terms of pitch, which makes the
     sound more choppy and less smooth.

   * Envelope 2 defines the sound of gunfire, both for our Spitfire and for the
     Theme aliens.
