## 8.2. Usage tips

The full listing of the options is available in the manual page. Here are just a few tips:

- Use the `channels` option. An example:

      -radio channels=104.4-Sibir,103.9-Maximum

  Explanation: With this option, only the 104.4 and 103.9 radio stations will be usable. There will be a nice OSD text upon channel switching, displaying the channel's name. Spaces in the channel name must be replaced by the "_" character.

- There are several ways of capturing audio. You can grab the sound either using your sound card via an external cable connection between video card and line-in, or using the built-in ADC in the saa7134 chip. In the latter case, you have to load the `saa7134-alsa` or `saa7134-oss` driver.

- MEncoder cannot be used for audio capture, because it requires a video stream to work. So your can either use arecord from ALSA project or use `-ao pcm:file=file.wav`. In the latter case you will not hear any sound (unless you are using a line-in cable and have switched line-in mute off).
