On the 29th February, I guided a group
of year 5 children at Cage Green in Tonbridge. They Brainstormed,
scripted and recorded their Podcast.
Jingles and intro music was composed on Garage Band on the Mac mini.

Chipmonk mp3 Playback
16/02/08 08:44 | Permalink
FAQ: My mp3 recording sounds fine when I play it back on the
software that I recorded it in, but sounds like chipmonks when
downloaded as a Podcast.
The main issue is that you are playing the Podcast back using a player that can not cope with the sampling rate. If it is played in a Flash based player this is almost certain to be the problem. Flash Player only supports two sampling rates: 22050 and 44100. Most other players - including Audacity, can play tracks of different sample rates and sound totally normal.
The article here explains the issue and a possible solution by resampling (involves getting your hands dirty in the command line!):
www.boutell.com/newfaq/creating/chipmunk.html
Ideally all recording would be done at 44100 in the first place.
If the sampling rate is set at too high a value and needs to be reduced to 44100, this can be done from the track menu. See screencast video here.
The mp3 export from Audacity is rather crude and can lead the user into thinking that the file is being exported out at 44100, when it is in fact nothing of the sort.
The Lame encoder used by Audacity can have different front ends applied. These open up other features of the Lame encoder. One key one, is to force a fixed sample rate for exported mp3s.
See http://www.dors.de/razorlame/index.php for the free download for Windows.
Once you install Razerlame, click on the LAME button, choose the Audio Processing tab, and set the sample rate to 44.1 kHz. That will force the resulting mp3 to 44.1.
To be safe in future, export from Audacity as a WAV file, then encode as an mp3 externally as a second step.

Podcasts Quell Exam Fears

When exams are just around the corner, many students let fear of failure affect their performance. So why not video the dreaded GCSE results day, and make a podcast to show that it’s not as scary as it sounds? Windsor Boys School did just that, proving how podcasting can tackle a wide range of learning problems in unexpected ways.

The Levelator

The Levelator is software that runs on
Windows, OS X (universal binary), or Linux (Ubuntu) that adjusts
the audio levels within your podcast or other audio file for
variations from one speaker to the next, for example. It's not a
compressor, normalizer or limiter although it contains all
three.
