Hi --- I was webcasting last week through an pa system -- so I was going directly into my soundcard via a 1/8 inch audio cable from the mixing board. I selected the Stereo Mix Audio Recording Control and put the volume up and was not getting any input from my sound card to Simplecast or Audacity. I panicked, restarted Simplecast, checked my audio settings -- nothing seemed to work. So I closed and opened Audacity, and then I saw that the microphone was selected in the audio input in Audacity. I changed that to Audio Mix and that fixed the problem.

So what does this all mean? I think that Audacity may take over some of your Audio settings on your computers, so checking the settings there before you start streaming is important. I hope that this helps some of you.

Hello All,

    Very much enjoying the audio introductions. Just want to let you konw that I'm aware of the glitch that is leading to double posting of most introductions. Looking in to it know - should have it sorted out soon. In the meantime, please do take a look at the ID3 Tags screencast - noticing a lot of untagged audio.

Here is a little audio I created to help explain the use of a compressor in audio editing.

In a recent post, Leigh Blackall talks about the decentralization of education. He shows a vision where learning is freely available to all through the best teachers on the Internet.

This can be made possible if teachers loosen their coupling with institutions and create an independant prescence on the web. Each teacher shares her research interests, and findings with everyone over her blog, podcasts and the like. Teachers also build communities of learning on their website. Learning is promoted by conversations; synchronous and asynchronous. By giving assignments and publishing micro-contents that explain various concepts in the form of text, audio, video.

In a recent post I described my experiment with live online training.

Anyone who has tried recording both ends of an audio conversation would know that the voice of the person on machine the recrding is being done gets recorded significantly louder than the other participants. Leveling this difference is a manual process where we normalize and amplify certain sections in Audacity.

A new tool called Levelator automates this process. You give it a WAV file, and it gives back a leveled WAV file. It does work and pretty well too.

The best part is: it's free for non commercial use.
