A piece of [Hardware] that allows you to pick up broadcast radio on your computer.

Many TvTunerCards have a radio tuner built in.

!Tuning/Listening to the radio
You can use the "radio" application to tune and listen to radio stations. This is part of the xawtv package, but in [Debian] at least it is split into its own binary package:
  apt-get install radio

Here is a sample __~/.radio__ configuration file for it (based on Hamilton frequencies):
 # frequencies have 6 decimal places of precision?!
 [[Stations]
 # 91.4
 91400000=Concert Radio
 # 101.0 or so
 101000000=National Radio
 [[Buttons]
 1=91400000
 2=101000000

Gnome Radio is a nice gui for [GTK2] that can store frequencies and record streams onto disk as Wav, [MP3] or OggVorbis.%%%
RedHat users with Dags repo set up on Apt or yum can install `gnomeradio`


!Recording

1. Use the Gnome Radio program as above.

2. From the command line:

Step 1 - (Make sure your sound card's mixer is set to record from the appropriate device - eg from Line In if you are using a loop-back cable).

Step 2 - run the "radio" command or whatever program you use to get output to the sound card.

Step 3 - run the following commands (or put them in a script and run that). Press Ctrl-C to finish.
----
 #!/bin/sh

 # -c 1 for mono

 # -s signed/-u unsigned, -w words (2byte samples)
 datatype="-s -w"

 # cd quality sample rate
 rate="-r 44100"
 # this is fine for voice recordings
 rate="-r 22050"

 # I like ogg.
 encodecmd="oggenc - -o out.ogg"
 #If you prefer mp3, you could install "gogo" and use
 #encodecmd="gogo stdin out.mp3"

 sox -t ossdsp /dev/dsp -t wav -c 1 $rate $datatype - | $encodecmd
----
Note that these commands aren't really radio-specific - they could be
used for recording anything, although the settings here are ok for radio-quality audio. Also, if you use [ALSA] then you will need to have [OSS]-emulation drivers loaded.
