Thoughts about tomorrow's Koreabridge Webast


Been gathering my thoughts in preparation for tomorrow's Koreabridge Webcast. Topics that I'd like to address at some point - either tomorrow or during future webcasts.

  • The Vision/Big Picture
    -a media channel that helps  those interested in Korea connect, learn, and collaborate
    - how  Pweb/KB fit into Worldbridges
  • Standards & Values
    - where do we draw lines?
  • The Business Model
    - show who the money?
  • Community Contribution
    - giving back, starting last year
  • Content Producers
    - what's in it for them?
  • Ratings & Reviews (businesses, employers/recruiters, content)
    - balancing the value of crowdsourcing with the headache of potential lawsuits
  • Forums
    - consolidation?  range of categories?
  • Advertising
    - more than banner ads, interactive advertising
  • Other Sites
    - collaborate if interested, cordial co-existence (no Pweb mafia)
  • Tech Stuff
    - Drupalers wanted,  OpenX vs Google Ad Manager,

Live, Interactive Webcasting Guide (for Windows users)


How to stream a Live Interactive Webcast from a Windows PC's
(Mac users, check out Alec's Guide and Mac Screencasts here)


What you'll need

Internet Connection
In order to webcast, you need a stable internet connection that provides at least 100kbs upload bandwidth (which means dial-up connections will not work).  If you plan to have more than one or two people in a skype call, you will probably need a bit more than that.  You can test your bandwidth at , ,or .  You can install NetMeter on your computer to measure and collect real time data on your upload and download speeds. 


  • Soundcard - you will need a soundcard that has 'stereo mix', 'What U Hear', or 'Wave out mix' as a recording option. 
    Many recent Dell computers do not come with this option, but you can find information about a work around here.
  • Microphone - It is necessary to use either a desktop USB mic like this or  USB Headsets like these which have two separate inputs for  the mic and ear piece. Models that have been confirmed to work include:Non-usb headsets or USB headsets that do NOT have the two separate inputs for mic and ear piece will not work and may cause severe anxiety for webcasters attempting to use them!  Actually, with some soundcards it may be possible (as shown in this screencast), but echo issues have always prevented this from being a viable option. If you can demonstrate otherwise, please let us know. 
  • Computer Specs - There are no other fixed minimum hardware requirements, but webcasting with anything less than 512kb RAM or the equivalent of a Pentium 4 would probably be pretty difficult.


Capturing both ends of a call

The major challenge of producing a live interactive webcast is capturing both ends of a telephony call in a way that it can be streamed. If all you want to do is record both ends of a call without streaming it, there a number of programs that can be used (see this page for more info).  To do so in a way that allows the audio to be streamed live, it is necessary to use an audio bridging tool like Virtual Audio Cables along with the hardware described above.  There are other ways to do this, additional hardware and/or software is usually required.

Setting up your microphone and headset
  • If using a USB Desktop mic, plug it in to any USB port.  Plug any headset into your standard speaker jack.
  • If using a USB headset (with separate jacks for mic and earpiece), plug it into any USB port, remove the earphone jack and plug it into the standard speaker jack as shown below.

Configuring your computer so you can capture both ends of a telephony call.
Parts of this will vary from computer to computer and it is possible that webcasters will need to go through some trial and error to get this working.  The most common places to alter settings are your Windows Volume Control, Sound & Audio Device Settings, & your Telephony audio settings. 
  • By default, most computers are set up to record from your microphone.  This needs to be changed. Using Windows Volume Mixer, set the Recording Control Properties of your soundcard to 'stereo mix' , 'What U Hear', or 'Wave Out Mix'.  With some sounds cards you will select his item, with others you will make sure it's unmuted'. 
  • In Sound & Audio Device settings, select your sound card as the recording device in the 'Audio' and 'Voice' tabs. 
  • Open Audacity.  In Edit/Preferences/Audio I/O , select your sound card as your recording device. 
  • Open the Audio settings of your telephony program.  In Skype, it's under Tools/Options/Audio Settings. For microphone, select your USB microphone.
  • Install Virtual Audio Cables (the trial version will work for experimentation purposes, but to produce actual webcasts, you will need to purchase the full version (US$30). Go to Virtual Audio Cable in your start menu and click 'Audio Repeater'.  In the 'wave in' section, select your USB mic.  In 'wave out', select your sound card.  For total buffer, select 100. You can experiment with the other settings, but it shouldn't be necessary to change any of them.  Press 'Start'. Open the Audio settings of your telephony program.  In Skype, it's under Tools/Options/Audio Settings. For microphone, select your USB microphone.
  • If all is working properly, after you press start, you should hear an echo when speaking.  You are now capturing all audio on your machine - your voice, voices of others in the telephony call, audio played from media players, program noises, etc. (Note: you might want to disable  notification noises in Skype and other IM programs)
  • Call someone (you can call skype lady at 'echo123'). Press record in Audacity, and you should see that you are recording audio when you speak and when the other person speaks. If so, you're ready to move on to streaming. If not, let the troubleshooting begin.

Live Interactive Streaming 

 Once you've succeeded in capturing all audio on your computer, there are several ways to stream this audio so others can hear.
  • Commercial Streaming Services  - sites like and allow users to stream from their servers for a monthly fee (US$10+/month)
  • Free streaming Services - an ever-increasing number of sites like, Mogulus, Yahoo Live, BlogTV,,, and  allow users to stream for free.  Most of these are video based, but can be used to stream audio only. 
  • Worldbridges Shoutcast & Icecast Streams - after participating in the Webcast Academy, 'interns' can apply for webcasting permission from any streaming community that is part of the network. In order to stream to a shoutcast or icecast server, you need to install a streaming program on your local computer.  Examples include Simplecast , SamBroadcaster, Oddcast, & Winamp
  • It is worth noting that online presentation tools like WizIQ and DimDim (free) and  Adobe Acrobat Connect and Elluminate (very not free) can also be used to facilitate online conversation and do not required the audio setup described above.
Whichever method you use to stream, you'll need to set 'microphone' or 'audio in' to your soundcard.  Most of these tools provide a way to automatically record or 'archive' what is being streamed.  Webcasters may want to use Audacity to record as well because it provides a higher quality source recording and also provides a more accurate way to measure audio levels during a webcast.  Below are step-by-step instructions for using Simplecast and to stream

Simplecast is a commerical program available from that can be used to stream to a shoutcast or icecast server.  There is a free trial version that does not expire.
  • Open Simplecast.  Click 'Start'. Then, click 'Config' and on the  'General Options' page, select your sound card under 'Capture Sound from Device'.  Click OK. 
  • You should now see volume meter movement on the right side of the main Simplecast Window. 
  • Click 'Encoders'.  Click the '+' sign to add an encoder and choose either 'mp3 and mp3Pro' or 'Legacy mp3'. 
  • In the 'Converter' tab, select  a format.  Higher bitrates (kb/s) will result in higher quality audio with less stream delay, but may cause problems for those with relatively slow internet connections. 

  • In the 'Server Details' tab, choose the appropriate server type, and enter the access information for the server you're using. 

  • In the 'Stream Archive' tab, check 'save stream to file' and browse to find the directory in which you'd like to save the recording.

  • When you're ready to stream, RIGHT click the encoder and click 'start'. You should now be streaming. To check the stream, go to the 'listening' page for that stream (i.e. ) and click one of the media player icons.  You should be able to hear what is being streamed (with a 20~60 second delay). 

  • First you will need to register at
  • Then click 'Broadcast Now' or if you've created a show, click 'My Shows' and then 'Broadcast Now'. 
  • Either way, the Broadcaster window should pop up.  Click 'allow' when the Adobe Flash Settings window appears. 
  • Uncheck 'video broadcast' unless you plan to stream video.  Select your soundcard where it says 'Audio Source'.  Maximize audio quality unless you notice bandwidth problems. Check your Ustream Volume setting to make sure it isn't peaking too much (volume meter will show red if so).  There are additional settings and tools you can use toward the bottom of the window (Advanced settings, create poll, cohost, etc.). 
  • When you're ready to start streaming, click 'Start Broadcast'.  If you'd like to create a Ustream recording as well, click 'Start Recording'
  • To check your stream, go to your Ustream listen page (i.e. or anywhere you've embeded the Ustream player and click the play button.  You'll get some echo when listening, but should be able to hear what is being stream with very little delay.

ETT Assembly Thoughts

Toward the end of tonight's ETT Community Assembly, Dave expressed strong opposition to including policies against using offensive words during webcasts.  I use the word 'offensive' after considering several others - obscenity, indecent, vulgar, curses, swear words   None of those seem to fit.  'Foul language' might  be appropriate, especialy in this case, but of course I'm  talking about Carlin's seven words and the like  (Thanks George for many laughs and for adding a lot to the conversation)

. In the context of ETT Policies and Worldbridgyness,

  • Sensitivity to offending others vs. Freedom of Expression &Genuinenss of Conversation
  • Dave's Legislation Concerns?
  • Standards vs Rules?


Well, that's what I'm thinking as I head upstairs.  Got a full day on the road ahead, so will ponder these and other matters as a wander my way through the New England countryside.

full count with 2 outs in the 9th and…


Had the Red Sox-Yankees game on, and just before what could have been the game-winning pitch, Fox switches to Nascar.
Of course, my first immediate concern was getting reconnected to some kind of live coverage. First stop, .

Not surprisingly (but still to my dismay), I got this when clicking gameday


At the time, I didn’t even think of radio. I don’t really have an am/fm receiver in the house other than the Net

Next stop was . At first search I was able to immediately commiserate with other fans and upon refresh a few seconds later, got news of the final out.

Not quite the same as hearing the crowd roar and collectively hold its breath with each pitch, but compelling in it own way.


 Two minutes later, I returned to and found this graphic of the last at bat.


This picture is easily worth a thousand words… and could support a variety of language learning possibilities.

Was working on the graphics unit for Media Week in EFL537 earlier this evening and still need to put together something on social media. This little episode has provided some useful demo material for both.
