Or another similar program? All I want to do is record the sounds coming from say firefox, or any other app, for use as samples in music. I need to do this in both windows and linux (ubuntu 9.10).

I have looked through the preferences of audacity but didn't find anything that let me select the system sound. Perhaps I overlooked it, because I was able to do this with earlier versions of audacity.

In Windows Vista, I had to do the following:

  1. Go to Control Panel > Sound > Manage Audio Devices
  2. Select the Recording tab
  3. Right click an item or blank area on the list of devices and enable "Show Disabled Devices". This made the Stereo Mix device appear.
  4. Right click the Stereo Mix device and select "Enable"

"Stereo Mix" was then available as an input device for Audacity.

For me, recording devices doesn't list 'Stereo mix' :( –  Colonel Panic Sep 22 '12 at 16:14
    
@ColonelPanic - Was missing for me too (even disabled/disconnected), but I found a thread where users reported downgrading their RealTek driver to make it reappear. Search Google for version 6.0.1.5322. If Windows keeps saying you have the latest driver, see this thread. In "Have disk...", select the "HDX.inf" file, which for me was under "Vista64" in the driver package I downloaded from CNET. –  Andrew Cheong Aug 28 '13 at 17:27

Windows and Linux

In the drop-down menu on Audacity's mixer toolbar, choose “Wave Out” or “Stereo Mix” as the input source. (The exact name may be different, depending on your computer's sound drivers.) When you press the Record button, Audacity will capture whatever sound is playing on your computer's speakers.

There is no "wave out" or "stereo mix" in that dropdown box on the mixer toolbar. The is nothing that resembles what you said. I would try posting a screenshot, but for some reason I can't do that when audacity has focus. –  Alex Feb 20 '10 at 8:37
    
@Alex - did you select your sound card as recording device in Edit > Preferences > Audio I/O? –  Molly7244 Feb 20 '10 at 12:52

On ubuntu with Pulseaudio you can route output to whatever you like, check this guide. On windows (at least on xp, don't know wista or 7) you should have a "Stereo Mix" under Recording Devices.

In Linux you may achieve it with alsamixer or pavucontrol: http://manual.audacityteam.org/man/Tutorial_-_Recording_Computer_Playback_on_Linux

Hi, here at SuperUser, we prefer full answers that include some information on how to fix the problem. Citing sources is good, but we like at least the outline of the information to be stored locally. –  David Dec 18 '13 at 17:35
