 ## Opening a stream
 
-The easiest way to open a source or sink is with the default `PortAudioStream()` constructor, which will open a 2-in, 2-out stream to your system's default device(s). The constructor can also take the input and output channel counts as positional arguments, or a variety of other keyword arguments. If you don't specify latency and sample rate, PortAudio will use device defaults.
