Notes on Audio and Videocasting

Just notes - because it's good to share


First step: recording audio. See Audacity.

Second step: recording both sides of a conversation. There's a bunch of 3rd party applications. See

  • Recording Conversations with remote participants

Third: Streaming

None of these programs capture both ends and push it out.

Use Virtual Audio Cables - Tools

Then streams out to shoutcast server using simplecast. (Or an open source program called icecast (but it doesn't support mp3 well))

or -


You're essentially using nicecast -


Jing -

Screen sharing - live sharing of computer screens

Video streaming - free hosted service

To connect audio and video to computer - Pinnacle device - takes audio and video cables in one side, and provides a/v computer inputs out the other side.


  1. just got a Samson Zoom H2
    awesome for recording even round table talks, radio quality, goes for 200 bucks

  2. I have Jing, but prefer Why?

    Jing: 5 minute limit (right?)
    SOM: 15 minutes (pausable)

    Jing: download
    SOM: web-based

    Jing: popup annotations possible? (not sure)
    SOM: popup annotations wherever you want them.

    Etc, e.g.:
    SOM stores your movies on your own channels, allows multiple size embeds (unfortunately iframe format, but oh well), downloads as .mov, and the online screencasts are beautifully high-resolution. Voiceover included, of course.

    Thanks for the nice resource. It is nice to share.

    (Thanks for Will R's speech video too.)
