A parametric whistle or horn is a synthesized sound, built in-game with the Whistle Editor or Horn Editor (reachable from a car’s Customize… window) and exported as a .rrwhistle / .rrhorn params file. A Whistle or Horn definition can reference this file via paramsReference, as an alternative to a plain audio clip. The sound is synthesized from a small set of authored parameters (additive/spectral synthesis) rather than played back from a recording.
