Transmit 12 bit audio using Teensy 3.1's built-in digital to analog converter.
| Port | Purpose |

| In 0 | Audio Channel |
This object has no functions to call from the Arduino sketch. It simply streams data from the ADC to its output port.
Signal range is 0 to 1.2V
Most applications require at least a 10µF DC-blocking capacitor.

The output rate is 44.1 kHz (no oversampling). Ultrasonic noise present if not filtered. This may not be an issue for many uses, but care should be used if amplified and driven to high power tweeters.
