Yes. Use this example. https://github.com/PaulStoffregen/Audio/blob/master/examples/WavFilePlayer/WavFilePlayer.ino

The version 1.0 library has a recording example. Open it with File > Examples > Audio > Recorder.

A schematic is available….
Well that’s an interesting question. I wonder what you really mean? Taken literally, of course both the left and right headphone signals are output, so you can’t input anything via the left headphone. You could get an input signal from the left line-in pin, or from the mic input.
But maybe by “send pulses of tones from right … to left …”, maybe you mean creating tones independently on the left and right channel, varying their timing and intensity, so as to create a stereo effect that causes the listener to perceive spacial movement of a single audio source? If that’s what you mean, then yes, certainly you could a complex arrangement of AudioSynthWaveform, AudioEffectFader and AudioMixer4 objects, and of course your Arduino sketch to control them, which creates really interesting timing and intensity varying effects.
But maybe you mean something else entirely?
If you really, actually meant using the left headphone as some sort of audio input device, well, I’m afraid this hardware won’t help. Even if the headphones you’re using actually are a dynamic speaker which can function “in reverse” to sense sound, the headphone output on this board is an amplifier which passes the signal only in 1 direction. There is a mono mic input and stereo line-in signals, meant for input of signals, so you’d somehow have to connect to those to actually get a signal input from the left to then use in somehow controlling the right.

No, don’t do that!
VBat is meant only for a 3V coin cell, and only to keep the RTC’s time counting while power is removed. It doesn’t power the whole board, only the RTC. Of course, the RTC only works if you add the 32.768 kHz crystal.
It is indeed polyphonic. Look at the library’s SamplePlayer example.

Maybe this will help?
Current measurements for 10 different boards, by “mantiou48”.
Here’s a message with quick/unofficial current measurements on the new 3.1 version.
TL;DR = 32 mA at 96 MHz , 23 mA at 48 MHz , 15 mA at 24 MHz
The speed is selected in Arduino using the Tools > CPU Speed menu.
Yes, it really truly does have 64K of RAM and tons of other features far beyond Arduino Uno.
No public wish lists :(
