//| AudioOut can be used to output an analog audio signal on a given pin.
//|
//| .. class:: AudioOut(left_channel, *, right_channel=None, quiescent_value=0x8000)
//|
//| Create a AudioOut object associated with the given pin(s). This allows you to
//| play audio signals out on the given pin(s). In contrast to mod:`audioio`,
//| the pin(s) specified are digital pins, and are driven with a device-dependent PWM
//| signal.
//|
//| :param ~microcontroller.Pin left_channel: The pin to output the left channel to
//| :param ~microcontroller.Pin right_channel: The pin to output the right channel to
//| :param int quiescent_value: The output value when no signal is present. Samples should start
//| and end with this value to prevent audible popping.
