What library is to be required for manipulating audio on the Arduino Due?

(a) AudioMan.h

(c) Audio.h

(d) Sound.h

This question was addressed to me in a job interview.

My doubt stems from Other Libraries topic in portion Arduino Programming of Arduino

Best answer
Right answer is (c) Audio.h

Explanation: The Arduino Due uses the Audio.h library for manipulation of sounds. It allows the Arduino Due to use the DAC0 and DAC1 pins to open .wav audio files from a source. Most of the time this library is used with the SD.h standard library to enable the Arduino Due to be able to read audio files from SD Cards.
