// ex5.cpp / Music 120 / Lecture 2
// Loops a sound sample file (arg. #1) at certain frequency (arg. #2 [Hz]) to DAC
// for a given duration (arg. #3 [s])
//
// Mac OS X with StkX:
//  g++ -g -o ex5 ex5.cpp -framework StkX -D__STKX__
//
// CCRMA Linux machines:
//  g++ -g -o ex5 ex5.cpp -I/usr/include/stk -lstk -lasound -ljack
//
// Usage: ./ex5 input_rawfile frequency duration
// Example: ./ex5 sinewave.raw 440.0 2.0
