# start up a network wrapper around a microphone, read via portaudio
device AudioRecorderWrapper
subdevice portaudio

If this text is saved in a file called grabber_audio.ini then the device can be created by doing:

yarpdev --file grabber_audio.ini

Of course, the configuration could be passed just as command line options, or as a yarp::os::Property object in a program:

Property p;
p.fromConfigFile("grabber_audio.ini");
// of course you could construct the Property object on-the-fly
PolyDriver dev;
dev.open(p);
if (dev.isValid()) { /* use the device via view method */ }

Here is a list of properties checked when starting up a device based on this configuration file. Note that which properties are checked can depend on whether other properties are present. In some cases properties can also vary between operating systems. So this is just an example

PROPERTY	DESCRIPTION	DEFAULT
device
period
subdevice
min_samples_over_network
max_samples_over_network
max_samples_timeout
name
start
