Had a great time at PAB2007 and met tons of fantastic podcasters. What a friendly and helpful community.
I wasn’t able to blog each presentation live, as intended, although I did take notes and so will be posting about other presentations heard this past weekend in Kingston over the course of the next few days.
So if you’re interested in podcasting, stay tuned. There are some real gems in there.
Many thanks to Bob Goyetche, Mark Blevis, Cathy Bobkowicz , all the presenters, and everyone else who helped make PAB2007 a real success.
Jack Ward of The Sonic Society gave us a brief overview of Audio Cinema, as he calls it.
Next time I hear War of the Worlds I’ll think of Jack.
Tip of the day : don’t blog directly into a web browser if you’re unlucky with computers. As I was finishing my blog entry on Andy Bilodeau’s presentation, a browser window error message popped up.
eek. Sorry. Guess this time you really did need to be there.
It’s Sunday morning and we have Internet access in the conference room, so I’m going to take advantage of it and blog live : I’ll post the rest of Day 2 topics later on.
Bruce Murray from Zed Cast is up first and he’ s talking about sound : some low cost and no cost solutions for podcasters.
5 key things that can make a difference – Bruce calls them 5 treats :
1. Treat your room
2. Treat your voice
3. Treat your mic
4. Treat your file
5. Treat your listener
Treat your room
According to Bruce, there are 2 things to consider : isolation and reverberation.
For podcasters who work in studio (or at home), the goal is to cut down as much ambient sound as possible. So turn off everything that makes interfering sound (air conditioners, fans, dimmers etc). The mic will pick up sound that you won’t necessarily hear when you’re recording. The goal is to create a dry sound. You can create ‘soft walls’ by hanging up packing blankets, drop cloths or screens, for example. Also, it’s important to avoid hard and parallel surfaces as well as corners. Setting up corner baffles is a solution. Reflection filters can be very practical, although an investment for podcasters. Bruce built his own out of recycled materials : cardboard tubes and foam.
Ground loop hums are caused by wiring or audio equipment. To avoid this, use the same plug strip for all your equipment. Separate power cords from signal cables to minimize humming caused by magnetic fields. If they must cross, cross them at right angles so they have the least amount of contact possible. Try to keep cables shorter than 2 metres, as coiling causes magnetic fields. Drop them loosely on the floor. To quote Bruce, the neat packing of cables is not your friend. Use balanced (XLR) cables.
Mobile podcasting brings a few solutions. Cars provide podcasters with the ideal soundbooth. Being able to move your podcast to a quiet area, such as a park, is also an advantage (in fact, someone said yesterday that he has podcasted from the local cemetery).
Treat your voice
Bruce recommends brushing your teeth, drinking water with lemon, avoiding dairy. Reading and rehearsing your script is important. Humming, sighs and stretches are important for vocal warmup. Standing up makes you sound more animated.
Treat your micUse windscreens. Pop filters. Shock mounts for microphones, to reduce vibration.
Treat your file
Try to get the hottest signal that you can without clipping. If possible, put audio on separate tracks, giving you control over volume. Free filters are available through programs like Audacity and The Levelator (particularly good for panel discussions). SpitFish, FloorFish and BlockFish are free plug-ins that can be very useful. Sound FX are available through ljudo.com, Free Sound Project and SoundoftheDay Podcast. Encode at 44.1 kHz to avoid the chipmunk effect.
Treat your listener
Fill out ID3 tags. Use consistent sound levels.

Thanks, Bruce, for these tips. A pdf version is available through his site.
Listening to podcasts inspired Montreal’s Hugh McGuire to launch LibriVox, an open project which, he claims, is the most prolific audio publisher in the world. LibriVox is part of the podcasting family that seeks to open things up and construct on a non-economic model. McGuire feels that evidence-based thinking and decision-making … or the ability to manage data … is part of what gives humans an evolutionary advantage. Societies are most stable when they are able to solve problems. The basis of democracy is to open data up to many people and allow them to make decisions based on that data. McGuire proposes that opening data to more people means more problems can be solved, which, in turn, creates a stable society.
As an example, he talks about a podcast for OBGYN residents, as a platform to exchange information and share learning.
Conclusion? Podcasting will probably NOT save the world, but it’ll help.
