When you send a tone to a speaker with the standard tone library, the loudest is at 50% duty cycle (only on half the time). Which at 5 volts, is like sending only 2.5v to the speaker. With toneAC2, we're sending out of phase signals on two pins. So in effect, the speaker is getting 5 volts instead of 2.5, making it nearly twice as loud.

How-To #5 TM Make Arduino Tones Louder | 251 HT The Arduino™ can generate what can be called a passable tone using the function tone(). This How-To shows how a few inexpensive parts can be used to make these tones dramatically louder than those heard when a speaker is connected di-rectly to an Arduino™ output pin.

That said, I have only used the tone() function, which is part of the Arduino “language”. The tone() function is capable of generating a single tone, in only one pin at a time. Libraries such as the Tone library allow you to generate more tones, but use specific timers of some microcontrollers, which causes incompatibility with many boards.
