+soundin - Either a file, or a string that can be used to get an SFX
+vol - The volume of the sound, excluding falloff and pressure affection.
+vary - bool that determines if the sound changes pitch every time it plays
+extrarange - modifier for sound range. This gets added on top of SOUND_RANGE
+falloff_exponent - Rate of falloff for the audio. Higher means quicker drop to low volume. Should generally be over 1 to indicate a quick dive to 0 rather than a slow dive.
+frequency - playback speed of audio
+channel - The channel the sound is played at
+pressure_affected - Whether or not difference in pressure affects the sound (E.g. if you can hear in space)
+ignore_walls - Whether or not the sound can pass through walls.
