How To Make a Podcast.
Yesterday I posted my first podcast. I thought I'd take a minute to write down how I did it for anyone else so inclined.
Equipment
After asking some friends for advice (like Doug Kaye, Thanks Doug!), I used the following equipment:
|
Behringer Eurorack UB802, an inexpensive 6 channel, 2 mic input mixer.
|
- Behreinger Eurorack UB802 mixer.
This is an inexpensive mixer with two mic inputs. Both have phantom
power, which is needed to power the mic I used (see below). I spent
about $45 on this. There are other options, like the UA-25 USB Audio and MIDI interface which goes direct to USB, avoiding lots cable woes. Its much more expensive and is not a mixer, but its also compact and runs off USB power. Perfect for mobile use. I may pick one up yet.
- Griffin Technology iMic USB Audio Interface.
This is not strictly needed if your machine has a line-in port. In any
event, I like it because I use USB as a poor man's Powerbook dock and
this eliminates two cable plugs.
|
Behringer B-1 Studio Condenser Mic
|
- Behringer Studio Condenser Microphone.
This is a great mic at a great price. I picked mine up in Orem for less
than $90. Its not portable, as you can see from the picture. It comes
with a case, shock mount, and wind sock. The stand, I picked up at
Radio Shack. I was a little worried about noise from the floor and desk
through the stand, but it doesn't appear to be too big a problem. A
more portable option would be something like the Shure Sm58.
- Bose Quiet Comfort Headphones.
I already had these. You don't need noise reduction for this
application. I do think that closed air (i.e. covers the ears) do
better at preventing feedback and are more comfortable.
- An Apple Powerbook (1 Ghz with 1G of memory).
All in all, I spent about $150 on equipment I didn't have. You could
get by with a cheaper mic that plugs directly into the computer, but I
tried that and you can definitely tell the difference. I figured it was worth the $150 to sound a little better since I sound bad enough as it is. :-)
Software
The software set up that I used was Dave Slusher's recipe for OS X podcasting at Evil Genius Chronicles. Dave's recipe is good. I had a few comments:
- Soundflowerbed seems to be very touchy. You use it to get the
audio from the Soundflower channel you've set up as a sound bus out to
the headphones. I had to start and stop it multiple times to actually
get it to route sound and it crashed at times.
- There was a delay from the mic to the headphones that made
speaking difficult since you don't hear yourself until a little while
after you speak. Consequently, I turned off the headphone feedback when
I was speaking. This was OK for soliloquy, but wouldn't work for an
interview on the phone.
- Audacity works well, but has a steep learning curve. For someone who's never
edited sound before, it was an interesting experience. I'm not above
paying money for something if its easier to use. Suggestions?
The one thing I used that's not on Dave's recipe was my hacked version of ListGarden.
I used that to create an RSS feed with the enclosure. I could have just
put it in my regular RSS feed using Radio, but I decided to create a
separate feed for podcasts and ListGarden makes that really easy.
Technique
Here was my technique. Feel free to critique if you've got suggestions that will help be do this better.
- Load the full Gillmor Gang into Audacity. Listen to it and make comments to myself on a label track.
- Go back and re-listen to interesting bits based on my comments. Record the response to them right there on a separate track.
- For each clip (I had 4 or 5), duplicate the original Gillmor Gang track and then cut out the right piece.
- Order the tracks vertically in the order I want to put them
in the finished piece. Audacity makes reordering tracks difficult
unless I missed something.
- Move them in time so that they follow each other. This is
easier to do my compressing time a lot, getting them mostly right, and
then expanding time to fine tune the placement.
- Delete unwanted tracks, edit the ID3 info, and export as an MP3.
As I mentioned yesterday, recording this took me about four hours. Dave
Slusher took me to task in response to me saying "Recording is hard
because when something goes wrong, pretty much the only choice is to
start again. You can't easily go back and change one sentence or remove
a mispronunciation (at least I can't).":
What
the? I do this every time I ever record one. In fact, in tonight's
episode I removed about 4 minutes of coughs, stammers and false starts
into topics that I decided to abandon. That's over 10% of the final
result. This suggests that the real core is in the last part, the "at
least I can't" bit. I'm curious to find out what Phil's setup is. Is he
using a tool that doesn't have a waveform editor? If so, he could
easily use Audacity for free anytime and would have that capability.
Or, is this just a case of failing to RTFM? Folks, you can in fact edit
the audio, remove mispronunciations or even insert new sentences in
place of burbled or erroneous ones. I do it all the time...
I'm sure Dave's right, but its just felt like I was swimming in
molasses and faced with the prospect of inserting some material in the
middle of another clip and removing and repairing several verbal
bobbles, it just seemed easier to rerecord it to me. Certainly, as I
gain experience with Audacity, that wouldn't be the case, but I don't
think you can argue that its as easy as cleaning up text. Text has some
very nice properties.
That said, audio has other properties. Doug talks about IT Conversation's ability to give you back bookmarks on audio clips so that you can reference them in a blog. That's nice for somethings, but I wanted to say what I was thinking, not just write them. That's the beauty of podcasting.

A lazyweb request after reading this: Someone should register the domain "phoneswap.org", and build a quick website (no - not a business) that does two things: 1) acts as a clearinghouse where you can post the phone/technology (and carrier if it's locked) that you have, and the carrier/technology that you're switching to, and 2) has a community-supported "how to" on helpful hints for swapping contacts - perhaps even technology-assisted. If you just want to get rid of an unused phone or other device or pda, you could be offered the option instead to formally accumulate whuffie. [Ray Ozzie's Weblog]

Nokia Leaps into the Future. Nokia Stuns Everyone
"Well, much to our surprise and delight, that Nokia phone we reported on yesterday turned out to be real. But it's not called the 7800, it's the 7600. And further stunning everyone, Nokia's also coming out with about a million other new products today. Besides the 7600 Imaging Phone (which is a WCDMA/GSM phone with a 65,000 color display, Bluetooth, and a built-in digital camera), Nokia also unveiled a new line of "Imagewear" products for displaying and viewing digital photos, including two medallions with tiny LCD screens, two digital picture frames, and a digital photo kaleidoscope.

Changing World Technologies. This company is about to open the doors on its first commercial plant. It is working with ConAgra to turn turkey offal (a byproduct of Turkey processing) into light commercial quality oil, natural gas, purified water, and commercially valuable minerals (all at very high quality levels). Amazingly, this same plant can process just about anything (from plastic bottles to sewage) and turn it into commerial materials without any nasty byproducts. Economic analysis indicates that the plant will produce oil at an estimated price of $15 a barrel (which is commercially competitive). The process involves changining the waste products at the molecular level. This could mean that landfills may become valuable sources of raw materials for reprocessing and that recycling will become a thing of the past (no downcycling of plastics for example). Very cool and seemingly credible. If the claims are correct, we should see these plants become ubiquitous in the next ten years. [John Robb's Radio Weblog]

Protecting and Improving Democracy: Canadian Style. The Prime Minister of Canada, Jean Chretien, recently submitted Bill C-24 to the House of Commons entitled Act to amend the Canada Elections Act and the Income Tax Act(Political Financing). He then delivered a speech about Democracy and how it has been corrupted in the United States and how it will be improved in Canada. Mr. Speaker, democracy is a living thing. The history of the world teaches us it is a fragile thing, as well. To be nurtured. To be encouraged. To be promoted. And to be defended. I know philosophers say that there is no such thing as a "perfect democracy". Of course that is true. Any society is a work in progress. But the truest test of a living, growing democracy like Canada is the extent to which our institutions strive to live up to our ideals. For it is in continuing to measure ourselves against our ideals that we reaffirm their power to inspire....In the United States the fitness of a candidate for office is judged first on his or her ability to raise huge sums of money. Rather than on his or her brains or ability to lead. They call it the "money primary", Mr. Speaker. And it takes place in the shadows. Long before an idea is expressed. Before a speech is given. Before a vote is cast.1 [kuro5hin.org]

One of tomorrow's innovations. More links for Radio weblogs. It's going to point to the blogroll OPML, if it's present; and to mySubscriptions.opml, and a change in the format for the link to the RSS feed. We won't release the code until tomorrow, to provide a very brief comment period. My Radio weblog already has the three types of links in its head. View source to see what they look like.

New Radio 8 feature. Now you can post to categories without posting to the home page. If you have categories enabled, there's a new checkbox, the first one, called Home Page (it effectively becomes a category). By default it's checked. Now you can easily publish multiple weblogs, going to lots of different locations, from one edit box. Screen shot. [Dave Winer: Radio UserLand]
