Recently, I’ve been assisting instructors interested in offering podcasts to their students. Since many others write articles on podcasting basics, I won’t belabor those topics here (unless, of course, I get requests for it). Instead, I intend to share some tips on topics that I don’t see others covering, starting with building a music and sound effects catalog.
When used effectively, music and sound effects give podcasts a professional quality - introductory and “outtro” music, background music, pieces of music separating show segments, and sound effects all contribute to a podcast’s polish. In some cases, like the podcasts (or “netcasts”, as Leo likes to promote) offered by the TWiT network, music choice sets the mood for the show and helps establish a brand. However, it already takes so long to record and edit podcasts without adding additional audio that often people find they don’t have time to add that extra polish. With the right tools and resources, I’ve found I can collect and maintain an easily-searched database of podsafe audio, ready to drop in podcast episodes in minutes. Generally, the steps I’ve taken to build my podsafe catalog include:
- Collect the music using Firefox and DownThemAll
- Import music into MusikCube
- Rate and tag songs as I listen to them
- Prepare frequently-used songs with desired volume, fade and trim edits
After the jump, I’ll cover each step in depth.

A friend recently had an interesting problem - he wants to promote the use of podcasts to instructors as a component of courses taught online, and identified the excellent, open-source Audacity as their Windows tool of choice. However, as he began writing documentation for installing and using Audacity, he realized many instructors would be immediately turned off by the complicated installation process required to set Audacity up for exporting projects as mp3 files - many instructors who could otherwise be taught how to record and save projects would not understand how to unzip LAME, copy the DLL file into Audacity’s folder, then point Audacity to the lame encoder. Instead of writing thorough documentation that would likely daunt non-savvy instructors, I suggested an alternative - creating our own installer. It worked so well, I thought others might benefit from the idea.
First, a word about licensing.
I originally wanted to provide the one-step Audacity/LAME installer as a downloadable file, but started reconsidering after looking into license issues. Audacity and LAME are themselves covered by GPL/LGPL and therefore are re-distributable; however, I can’t tell what the SetupStream license terms are, and the patent mess covering the mp3 format may prevent distributing a package that installs Audacity with built-in mp3 output. Since I can’t really tell, I listed the steps required to make your own installer, and you can choose how you use or distribute it.
Step 1
First, I downloaded the tools I’d need. Since I was creating a custom installer, I needed the zipped version of Audacity, not their installer. Additionally, I needed LAME and an installation creator with the ability to insert registry keys. After trying a couple install creators, I chose SetupStream - it’s easy to use, freeware and offers a wide array of features, including all those I need.
Step 2
Next, some preliminary steps: unzip Audacity into its own folder, then unzip the file lame_enc.dll from the LAME zip file into the the same folder that contains Audacity.exe. Install and start SetupStream, select Create New Setup and click Next.
