Thanks to Stéphane for helping me create this working example:
// Test soundfile primitive
//
// USAGE:
//
// > faust2caqt -soundfile tsndfile.dsp
//
// Doc: https://faust.grame.fr/doc/manual/index.html#soundfile-primitive
gate = button("gate");
inc = 1;
play(i) = i, _~(*(gate):+(inc*gate)); // play i'th soundfile
process = play(0) : soundfile("son[url:{'/w/s/wav/uh-oh-.wav'}]",2):!,!,_,_;
// or soundfile("label[url:{'path1';'path2';'path3'}]", n);
