Stream What You Hear

Have you ever been in a Skype call and wanted to share your current music with your friend on the other line? Or do you want to add some more interactivity to ustream.tv by letting viewers Skype in questions? You can accomplish this, as well as recording of anything you hear through the use of two simple programs which let you create a loopback audio device. (There is also a screencast.)

Mac OS X only! (Tested on Intel MacBook Pro)

  1. Go grab yourself a copy of LineIn (I used 2.0.2) and install it.
  2. Download SoundFlower and install it. (Remember to drag SoundFlowerBed into your applications directory - you’ll need it later)
  3. Restart your computer as prompted.
  4. Launch LineIn (Applications > LineIn.app).
  5. Set the Input From to Built-in Microphone: internal microphone (or whatever your input device is).
  6. Set the Output To as Soundflower (2ch).
  7. Click Pass Thru and hide LineIn.
  8. Launch Soundflowerbed (Applications > Soundflowerbed.app) - it was on the Soundflower disk.
  9. A flower icon will appear in your menu bar. Click it and a menu will appear.
  10. Under Soundflower (2ch)click Built-in Output. (Or whatever your chosen speaker device is)
  11. Open system preferences and then sound preferences.
  12. Under the output tab, select Soundflower (2 ch).
  13. Under the input tab, select Soundflower (2 ch).

Are you a visual learner? I have a screencast of steps four through thirteen for you.

Now your default input device is the Soundflower (2 ch) which includes all the sound you hear as well as everything you say. Some applications may not respond to this change immediately but will require that you set the input/output device to Soundflower (2 ch) - which should be both your input and output device for all applications besides those specifically listed above. For instance, in usteam.tv you must click Advanced Settings and then select Soundflower (2 ch) under Audio Settings. If you need help with a specific application or don’t understand this procedure, don’t hisitate to comment. If everything went great for you, have fun streaming your audio and please consider digging this.
