summary
Good primer on Podcasting
The power of XML is yet to be fully recognized, but its expression in podcasting has far-reaching effects and consequences all by itself. Way beyond extending audio distribution over the Internet and providing relatively easy access for creative types to a global distribution channel, podcasting may alter and extend the distribution of content in ways never experienced before, having repercussions for political communication, social expression, and democracy itself.
Podcasting can be considered, in general, a melding of several elements: digital audio, weblogs, radio, Tivo-like recording/playing devices, and RSS (Really Simple Syndication). RSS is the protocol extending XML allowing creators to publish content to audiences who can easily subscribe and partake remotely in both space and time. It is much more than merely an alternative to conventional radio.
Given all of this asserted importance, the new book, Podcasting Hacks: Tips & Tools for Blogging Out Loud is perfectly timed to provide guidance on how to find, listen to, and subscribe to podcasts as well as how to create, publish, and market audio and video content. This is a comprehensive introduction to nearly all aspects of podcasting. It covers not only the technological elements but the content and creative elements as well. Much of the later material draws on analog sources like radio and television broadcasting. Many of the content elements are shared across the technology distinctions. Good interviewing techniques and content stylings, for example, are the same regardless of how produced and distributed. The major theme here is how to produce quality audio which can attract audiences via digital distribution over the now ubiquitous Internet.
The book has 11 chapters covering how to find podcasts, starting out in listening and creating podcasts, producing quality sound, using formats, interviewing, blogging, publicity, basic editing, advanced audio, mobility, and video blogging.
The main author is Jack D. Herrington, a software engineer and developer and technology writer and reviewer. There are 20 other contributors to the book, including journalists, multimedia consultants, radio and video producers, web editors, and podcasters themselves, particularly several who have popularized the medium.
The book has two main focuses - how to find and listen to podcasts and how to produce your own. The later focus consumes most of the book and deals with producing the best sound (with the lowest noise), producing interesting content, marketing, getting involved in the community, and even how to get your audio masterpieces into syndication.
Although this book is part of the venerable O'Reilly series of Hacks, the 75 "hacks" contained here work more like captions for various sub topics under the podcasting rubric. The book is less a collection of individually-packaged solutions to discrete problems or issues, but a primer on the whole of podcasting.
The first two chapters provide a list of the best and most popular podcasts, and directions on how to search directories of podcasts on the web. Apple's iTunes software broadly popularized podcasting only a short while ago by including a built-in directory of podcasts in version 4.9 of iTunes. How to get and use the right podcaster for your interests is explained, as well as some recommendations of specific applications - iPodder gets good reviews. Hack #2 offers a perl script which allows one to aggregate and rebroadcast feeds from other sources. Hacks 3 & 4 also describe perl scripts to build your own podcasts and to import podcasts into iTunes, (both PC and Mac versions.)
Using perl scripts is not for everyone, but the content of this book is fairly broad, having interest and value for a wide range of technological types, from higher level geeks to the person who is only casually interested in this new technology and content. Throughout, when discussing common software applications, the authors pointedly cover each of the main platforms - Windows, Mac OSX, and Linux and both technical production and content. Hack 10, for instance. is a technological hack; it relates how to create your first podcast using the freeware, Audacity. Hack 11 is a content-related hack instructing how to produce the content of a podcast and how to understand the respective roles of producer, writer, engineer, host, editor, and performer.
Surprisingly, one can get started producing podcasts relatively easily using a very modest amount of hardware and a little software, including mostly freeware or modestly-priced applications. The authors go out of their way in many of the hacks to point out how to select and acquire production materials at low cost. They often recommend specific products and services making it as easy as possible for readers to believe they can actively participate in podcasting with relatively modest efforts and budget.
The segments on formats describes what a format is in terms of duration, structure, content, and production elements. Some of the many types of formats are itemized and described - news, story show, personal show, political, mystery science theater, music, sports, technology, and news. The segments for each of these contains information on important sources for content, examples of use, and tips for producing content. Each type has its own strengths, limitations, and pitfalls. An overly enthusiastic personal show, for example, can get you fired from your job if your boss accesses and hears something he/she doesn't like. (It has happened more than once, according to news resources).
There is an enormous amount of material presented in this book with excellent attention to details. The audio theater type of format, for example, includes an itemization of the structure of a typical show - the story, script, studio setup, performances (with directorial prompts), mixing and encoding audio, and even how to make your own sound effects. Hack 33 describes techniques professionals use in producing interviews - types of interviews, location considerations, preparing guests, interviewing techniques, using environment sound ambience, and even microphone techniques. A large handful of the contributors make reference to how to use microphones properly emphasizing the need to control wind, voice pops, environmental noises and the like. There is even guidance on training one's voice for audio (Hack #19).
Virtually every possible element of podcasting is noted in this book. Some other topics include: how to record telephone interviews, including Skype conversations (#34); how to podcast using blogs (with examples of HTML and XML coding); how to manage bandwidth (#39); how to use ID3 tags for your audio to facilitate searches (#40); how to market, connect with the community, and even how to make money while podcasting (#48-49).
More advanced topics are handled later in the book. Learn basic editing using the right audio tools in Hacks#50-58. Hack 61 details how to set up a home studio. A very interesting section tells how to be mobile while podcasting including making a small recording rig for travel as well as podcasting directly from your car while driving. (Sounds unsafe to me and illegal in some states, as noted by the authors). Other sections take up, directly and at length, the legalities of podcasting covering copyrights, libel, licensing, and more. An interesting explanation of Creative Commons licensing is contained in #67 - 68. To cap it all off, there is a useful glossary of digital and analog audio terminology and an index.
As you might expect, given the presence of 21 contributors, not all hacks are as good as some, and there is considerable repetition of some elements, like microphone handling, production concepts, and others. However, these are small quibbles for such an information- packed volume of modest cost."

For not writing it "eXtensible Markup Language". That's so annoying.
First there were blogs which allowed to people to become amateur journalists and columnists. Now we have podcasting which allows people to become amatuer radio hosts and broadcasters. Probably the best evidence yet for the "Internet is the modern printing press" arguments.

Who has the infrastructure to account and pay for this sort of stuff? Professional broadcasters, mostly.
This assumes the music was written by an association composer. Perhaps you have some unsigned band that has granted you permission to use their material. You're clean.
Beyond music, there's spoken word. Performances have value, but many of the podcasts I've heard were more akin to written blogs than produced audio programming.
What Apple could do here, if they're so inclined, is to swing a podcast deal with their labels. Music purchased from the iTunes store would be licensed for personal use as it is now and non-commercial podcasting. If iTunes could be retooled to record voice-overs -- and it sounds if that may be coming -- you could build a podcast within iTunes and distribute it via Apple's music store. The podcasts would be playable through iTunes.
Apple's motivation in this is twofold: it would encourage podcasters to use Apple's platform and purchase their library through the Apple Store, and the podcast songs would be clickable. Listeners could buy whatever they like as they hear it.
It's a proprietary solution, but would finesse the licensing issue and make music podcasting more accessable.

Yes I see that there is a typo in my "typo". It was a legitimate misteak.
When I first heard about podcasting and podcasts, I really didn't have a clue what it meant. The name seems to make an inextricable link between the iPod and this content, which simply isn't the case. Admittedly the iPod is the leading portable mp3 players, and mp3 players are the major driver of this content.
But still. My parents here about podcasts. It's a buzzword. They don't care. I tell them they can download a radio show and listen to it on the computer; their ears pick up. They hated streaming shows almost as much as I did, but when they found out you could slurp the whole show in one go and listen to it at your leisure, they were into the technology almost as fast as they got into Google Earth.
Maybe it was the same with email way back when. I remember people asking me; "Email. What's that?". I had to explain to them that it stood for electronic mail and that you could send and recieve mail to and from other peoples "electronic postboxes". (No I'm not Korean). THEN they got it. Email was just a buzzword until then. But now the word email is ubiquitous, so perhaps the same will be true of podcasting.

Back then, the content was better too because not every 12 year old had one.
Not to feed a troll but this is what happens as a communications medium becomes more popular; you start to see a lot of drive behind stuff that is normally considered "the lowest common denominator" by the early bird crowd.
Just look at Napster, when it was a "geek thing" it was a quiet community with some great content and you could download a file without wondering if you were getting the right thing or if it was corrupt, etc etc... After Metallica started to scream about it everyone got on the band wagon and we had idiots who claimed that Lenny Kravit's version of American Woman was done by Jimi Hendrix and still, better yet, was completely mislabled content.
Now with e-mule I try to get a preview of my downloads ASAP to ensure that my Lectures on Physics by Feynman aren't actually some kind of fisting video. Like that's a real riot... geez...

Live-to-tape had been available to download for years, much as news has been available on websites for years.
RSS meant that you could aggregate news in one place without needing to browse through 20 different sites to see anything new. Likewise, podcasts mean you can get new episodes of content without needing to check manually and download.
As it happens, I quite like the fact that I pick up my iPod in the morning and some news is 'just there' for me to listen to. If you can tell me why manually checking for, downloading and copying a broadcast to your device is preferable to just letting an application automatically aggregate (Ooh, alliteration) 3 or 4 different feeds then I'm all ears.

IMO, the best podcasting "hack" that I have found is using del.icio.us to find, create, and maintain simple podcasts. Just use the tag "system:filetype:mp3" to find only MP3s. (Hint, it also works for other filetypes.)

I tell them they can download a radio show and listen to it on the computer; their ears pick up.
Try again: tell them that a computer program can download a radio show and all subsequent shows automatically on their behalf.
The difference between a podcast and "a show you can download" is that podcasting means syndication.
I don't care what we call podcasting, but calling it "a radio show you can download" seriously undervalues the magic of rss and feed aggregators.
Spoon not. Fork, or fork not. There is no spoon.
You could do it before, and I personally did it before. Crontab + small bash script = automated downloads of Hacker Mind ready for me to listen to at my convenience. Could even script it onto an mp3 player, had one existed yet.
"Podcasting" is not a new concept, its just a bad term (nothing to do with ipods, nothing to do with broadcasting) for something the rest of us have done for years. Sure, a little bit of standards involved is nice, but as long as you had a url for the stream and a timeslot, you didn't really need anything else.
Pain lasts, kid. Its how you know you're alive. Sometimes I think this growing up thing is just pain management-TheMaxx
Thing is, it's still just a scheduled task, nothing wonderous or fantastical in any way really. Delikver it to the iPod WITHOUT needing to plug it in to anything and you might have something slightly more novel there.
What's still nice about podcasting, is that it's an audio/visual medium that doesn't have to dilute itself. Established media produces content aimed at the widest possible audience, and therefore ends up not being appealing to anyone at all. Whereas, I can create a podcast targeted toward the hardcore gamers, and it can find a loyal audience.
Furthermore, by using RSS as the delivery platform, basement hacks like me can go up against established media. For example, my friends and I do a gaming podcast that is beating out established entities like PC Gamer magazine's podcast (based on subscriber numbers from yahoo and odeo).
But numbers aside, it's fun. We don't make money off of it, nor do we think we ever will... but we do it for the love. How can established media beat people producing content out of love?!

That's hot. Is it better than streaming video?
Heh. I honestly cant tell you but I can tell you that it wasn't suppose to be "Feynman's lectures on fisting". Infact he was not even in the video... what's up with that?

It is a lot easier to do this then any previous methods of recording live broadcasts.
Therefore, it will be used be a substantially larger audience, which mean more peiople will be able to get information outside mainstream media.
You seem to think this is about putting information on a device, it is not.
It is about any body with a computer being able to get an audience, to be able to broadcast any information they like without controls. It is about the people who create broadcasts.
Of course, the likes of you wouldn't consider the printing press new or usefull because scribes have been around, and all it is is a fancy scribe.
You also wouldn't have consider writing new and fantastic because you could just listen to the local sage.
In short, you have a small mind.
The Kruger Dunning explains most post on
Services like ClickCaster allow you to record Podcasts directly from the Web via a Java applet or upload your own MP3 files directly to their site. The RSS feed is then constructed automatically from metadata you enter along with the recording; sort of like a Blogger or LiveJournal for Podcasting.

I at least remember downloading mp3 files from websites via my old 56k in the 90s... To bad back then we didnt have a l33t word for it.

You could of course just pay for your Feynman lectures, rather than just stealing them.
Well, this is where you've made a horrible assumption, actually, a couple of them.
First, not all of Feynman's material is commercially available. So there is a number of "bootleg" files the if you really want them you need to resort to "stealing" them.
Secondly, I speak as living proof to the fact that often my P2P sampling has indeed lead to sales. I have bought a number of things after a "sample". I know there are plenty that don't but that's not me.
Dedicated Cthulhu Cultist since 4523 BC.
I agree with the point about some of his material not being available. However, the sampling argument is quite specious. You can sample most, if not all, of the commercially available work. Plus, if you know enough to listen to Feynman, you know enough to know the difference between stealing and not stealing.

Sorry to be a bit late on this...
Sampling 30 seconds of a lecture is not like sampling 30 seconds of a pop song. All too often you get into a situation where a lecture is only available on a large (and pricey) box set. Taking a 30 minutes lecture from a collection that holds 20 hours of content is pretty much sampling at that point. It's not like downloading the first side of Dark Side of the Moon and calling it a sample, that'd be more like hearing half of "Time" and calling it a sample.

Agreed. You should check out audible.com. I'm considering it for myself as well as for gift giving this holiday season.
