The key concept here is "tracks" as these are not isolated audio events but rather short compositions of multiple events: overlapping layers of sound effects designed to evoke excitement, panic, speed and so on (and they do this very well with the SFXtools namesake delivering as always). Despite the grouped format of each file it's also possible to isolate specific sounds for specific visual sync cues. Regardless of scoring visuals or working with audio-only this pack oozes quality and begs to contribute to your project.
