In this 11 minute screencast, I demonstrate how to use free software tools including Audacity, The Levellator, and Switch to “normalize” an audio recording before publishing it as a podcast. The process of normalization makes the volume levels in a recording more even, so the listening experience is better for podcast subscribers. The Levellator only accepts uncompressed audio files, like WAV files, to perform the normalization process. Switch software is handy to compress the resulting normalized file into a lower bitrate mp3 file which is MUCH smaller in size and faster to download.
Access the audio podcast mentioned in this screencast, “STEM ? Successfully Targeting Elementary Minds,” on the “Yukon PD Podcasts” website created as a free blog on Posterous.com. Access and subscribe to the free “Fuel for Educational Change Agents” audio podcast, also referenced in the video, on audio.speedofcreativity.org.
I used Screenflow software to create this screencast. If you give any of the techniques a try described in this screencast, please let me know via a comment or tweet.
