Audacity is an open source, cross-platform sound editing application. It is the sound editor I use for producing the PodLeaders and it@cork podcasts.
The process I use for producing the podcasts was:
- Record the interview using Skype and Wiretap Pro (with Wiretap Pro set to save as mp3)
- Import the mp3 file to Audacity and edit
- Export as mp3 and publish
After a recent conversation with Doug Kaye, I decided to try his Levelator application to get the levels on the recordings the same. This meant I had to change Wiretap Pro to output to aiff ( a lossless format) instead of mp3.
I did this and recorded a number of interviews successfully, saving the interviews as aiff. However, yesterday, when I went to edit the first of those interviews, I was disappointed that the Levelator couldn’t work with the files (gave an error and stopped trying to level them).
However, I was horrified when I tried importing the files into Audacity only to find that the imported files had massive echo problems, echo problems (!). No matter what I tried I couldn’t get rid of the echo and it made the audio useless.
Finally, I hit on a solution:
- Import the aiff files into iTunes
- Export from iTunes as mp3
- Import the mp3 file into Audacity – no echo (phew!)
I should have hit on this solution sooner but it had been a long day!

Just a suggestion re the sound levels. I know but have not used audacity but I’m pretty sure you will find a normalise function that will set the average volume to a set level.
If that doesn’t work then look for besweet which is an open source app for sound editing. Besweet allows you to normalise and convert to a multitude of formats.
You can probably find a whole lot more info over at doom9.net and their forums.
I listened to the podcast with Doug Kaye and was planning on trying his levelator. I guess you’re saying it doesn’t work? I recall him saying it works with aiff and wav files. I assume you only tried it with aiff. I’m reluctant to try it out since I know the feeling you describe above when you think the recording of the great conversation you just had hasn’t turned out for some reason. I guess a test conversation would be the way to go here.
to be honest – it didn’t work with the aiff files output by Wiretap Pro is as much as I can say. I wouldn’t hesitate to try it out if I were you. Make a copy of the file you are going to try it on first if you have any worries but it doesn’t modify the original file in any case, it creates a new modified file.
The problem I had importing the file into Audacity was unrelated to my use of the Levelator.
