Audio::Radio::V4L uses the Video4Linux interface to control radio receivers (eg. internal radio cards or USB receivers).
Open the device via open(). Get the highest and lowest supported frequency of the radio: get_freq_min() and get_freq_max(). Set the frequency with set_frequency(). Listen or record. Close with close().
Each public function/method is described here. These are how you should interact with this module.
