       mplayer radio://[channel|frequency][/capture] [options]


       -radio <option1:option2:...> (radio only)
              These options set various parameters of the radio capture module.  For listening to radio with MPlayer use 'radio://<frequency>' (if channels option is not given) or
              'radio://<channel_number>'  (if  channels  option is given) as a movie URL.  You can see allowed frequency range by running MPlayer with '-v'.  To start the grabbing
              subsystem, use 'radio://<frequency or channel>/capture'.  If the capture keyword is not given you can listen to radio using the line-in cable only.  Using capture to
              listen is not recommended due to synchronization problems, which makes this process uncomfortable.

              Available options are:

                 device=<value>
                      Radio device to use (default: /dev/radio0 for Linux and /dev/tuner0 for *BSD).

              + and -
                   Adjust audio delay by +/- 0.1 seconds.

Using MPlayer for Radio Listening

You can do a lot of things with MPlayer. An example of commandline syntax used for radio listening is:

mplayer -rawaudio rate=48000 radio://2/capture -radio adevice=hw=2:arate=48000:channels=93.8-Radio_Zones,94.7-SSR_1

Note that this command will work even without audio cable between the output of the radio card and a line input of the audio card.

This will start MPlayer with sample rate = 48 kHz (using the same sample rate that the sound card is using gives best results), listening to the second station on the list, the tuner is the third sound card (ALSA device hw:2). For more examples and syntax: MPlayer radio tips.

You can add as many stations as wanted and use LIRC to control MPlayer.

If you are, say, running JACK all the time, you can add

ao=jack,alsa

into ~.mplayer/config (for MPlayer) and mplayerplug-in.conf (for Firefox mplayerplug-in). For recording, you can use any JACK aware recording application.

A XDialog wrapper can be made for radio listening using MPlayer and v4l2-ctl. The authour found that it was so good that they decided to make it public under the name XDRadio. You will have to make a list of your stations during the installation (very easy to do). After that, all that is required is to just to run it and enjoy the radio.
