Podcasting History… It is Short

The last two days in the car; I have been listening to a podcast from IT Conversations. It was an interview with Doug Kaye the founder of IT Conversations by Michael Geoghegan on the Podcast Academy Channel. Doug talks about the history of podcasting on IT Conversations. If you have listened to podcasts from IT Conversations you will enjoy the interview. But I was thinking about my current predicament of trying to replace a co-host for The Global Geek Podcast and the history of podcasting.

A History Lesson

As mentioned in the interview the first “podcast” was accomplished by Dave Weiner the developer of the RSS format. He demonstrated the concept on his blog on the 11th of January 2001 after defining a new element called an “enclosure“. By the way he did this by “enclosing” a song by Grateful Dead on his blog feed of Scripting News.

For the first two years there were very few users of enclosures in RSS feeds. In September 2003 Weiner gradually released to his feed a series of 25 interviews with bloggers, futurists and political figures. Weiner announced these audio features on his blog as they were released. This threw out the challenge to other aggregator developers to support enclosures. As up until this point most feeds were text only.

In October of 2003 the first BloggerCon provided the platform for a demonstration by Kevin Marks of a script that enabled RSS feeds and pass the enclosures to iTunes for transfer to an iPod. Marks and Adam Curry discuss collaborating. After the conference Curry offers readers of his blog a script called RSStoiPod a script that moved mp3 files from on-line to iTunes, he encouraged developers to further the concept. Initial efforts were based in the command line. The first podcasting client with a user interface was iPodderX (now Transistr). The name change was due to the threat of legal action by Apple and trademark issues, obviously related to the iPod. From here the development of “podcatchers” or aggrregators was fast and mainly resided in the open source community with the show of Juice, CastPodder and PodNova. There are many aggregators now on offer and go from the simple to the highly sophisticated.

In September 2004 the term “Podcasting” was referred to as one possible; out of multiple terms for to listening to audio blogs, as coined by Ben Hammersley:

“…all the ingredients are there for a new boom in amateur radio. But what to call it? Audioblogging? Podcasting? GuerillaMedia?”

In the same month Dannie Gregoire used the term to describe the automatic download and syncrinisation of audio content. The name stuck and entered into common usage. Note the absence of anything related to an iPod? No it had nothing to do with iPods or Apple. In hind sight the association of the iPod with podcasting and podcasts has been detrimental in my opinion. As many people still to this day believe that you need an iPod to listen to podcasts and until I investigated the medium I too thought that the case. Or at least an association.

In September 2004 Adam Curry launched the ipodder-dev mailing list. A huge 100+ message conversation on Slashdot resulted in more attention in the development project. October of 2004 saw detailed “how-to-podcast” articles on-line. Then November 2004 saw the launch of Liberated Syndication, which offered storage, bandwidth and RSS creation tools. LibSyn for short, still provides the service to this day at some of the cheapest prices on the Internet.

As a final point, in February 2005 out rolled the first of the podcasting networks. The first was The Podcast Network, created by Cameron Reilly and Mick Stanic. The Podcast Network was and is the first Commercial Network. PodTech was founded in May 2005. Many others have followed and I think this is only the begining! I have every reason to be proud that The Global Geek Podcast lives at The Podcast Network.

So What has that got to do with Me?

Do you notice the dates in our history review? I use the word history very loosely as we can only say that it refers to past tense regarding podcasting and it’s past. Podcasting is a very new technology! In many respects the technology is still rapidly evolving and very dynamically at that. So being new it offers great challengers to the new user.

I would not say that subscribing and listening to podcasts is easy for the average user. In brief the user has to take the following steps:

  1. Realise what these strange links called RSS are (in addition to not writing it off immediately after seeing a page of RSS!)
  2. Source and install an RSS Aggregator
  3. Figure out how to subscribe to a feed, and realise that it is free.
  4. Know that not all aggregators are built equal (some support enclosures and some do not)
  5. Actually download a podcast using their tricked out aggregator
  6. Find some application to listen to it with or
  7. Figure out how to transfer the mp3 file to a portable mp3 player
  8. Enjoy

Phew! Now that is an effort. In reality most people probably start by right clicking and saving a podcast directly rather than use an aggregator. To try and explain to somebody exactly how to do all of the above is difficult and you generally loose the individual as soon as you mention aggregator. If you keep them that long.

Then I realised today, in light of listening to the interview with Doug Kaye that I can not expect every user that surfs by the Rooster’s Rail to know what podcasting is or what a podcast is. Given that; no wonder I have had bugger all responses to my plea for a new co-host. No wonder they might think that it is hard and intimidating or that they are not cut out for it. Or even that they have any idea what so ever and think I have a screw loose!

I think that the next huge leap in exposure to podcasting will be the simplification of the subscribing, downloading, transferring and listening process. It won’t be long until the manual procedure described above becomes a seamless automated process that the “average” user will be unaware of. Much of this I believe will come about when it is built into something like Windows Media Player. While that might disgust some people, the fact remains that most users use Windows! So it stands to reason. In addition to this factor will be the ever connected Generation Y, podcasts for them will be a thing that they have intergrated into their lives as a part of it rather than something they have to introduce.

So I have resolved myself to my crusade to expose as many people as I can to a medium that while young is transforming the global media landscape. In Cameron Reilly’s words “…this is something I have to do”.

Welcome to the revolution… For the rest of us that means hardcore brain cell re-programming.

What Bit Rate for Podcasts?

I really, honestly do not know the answer to this question. What is the best bit rate to encode a podcast at? Also does that answer depend upon the fact that you are a listener or a podcaster or hosting service?

I do the post production work for the Global Geek Podcast. Before moving to TPN I always encoded the podcast at 44khz and 96kbps. That works out at about 35 – 40MB per show (depending on length between 40 minutes to an hour). We have what I think is great audio quality, but am I spoiling ourselves and our listeners and potentially excluding others?

We have never had a complaint about the file size of the show. No-one has ever said it was too big. People have commented on the quality and said it is great and we have worked hard to get it that way. But I now question if that is over kill. So I tried to figure out what bit rate is the most common. I did a very small survey of the podcasts I have on the computer. I only have nine on it at the moment – most of them are on the MP3 Player (where they should be).

Anyway I got the following breakdown:

Total of 9 Podcasts:

  • 2 encoded at 96kbps
  • 4 encoded at 64kbps
  • 3 encoded at 48kbps

A conclusive survey that does not make. But maybe I am aiming too high. What quality do listeners expect of a podcast? Do they want a small file and lower quality so that they get the content without the bandwidth. Or do they want great quality and a larger file size? With the size of MP3 players now the storage is not an issue I don’t think. But I know in Australia the cost of bandwidth might be. The cost of faster connections is expensive and so many users are on a maximum of 256/64 or 512/128. So does a larger file size deter them from listening to our show? Could we have a bigger audience if we made it smaller and if that is the case what size is acceptable?

With the uptake of broadband technology there is a step towards encoding at a larger bit rate but what should it be? Perhaps 64kbps is a good place. I listen to quite a few podcasts that are recorded at 64kbps and they sound good. A one hour podcast encoded at 64kbps is about 28MB (voice only). Is this a big difference to 96kbps? Well it is between 10 and 15 MB. Will that mean the difference between more listeners and a balance between keeping your existing ones because of what they expect? Will you loose listeners by lowering the bit rate dramatically and will it matter because of the number you pick up. To me it does anyway, I care that we keep the listeners we have.

The other big consideration here is the hosting cost. I know that I had to go to the plan one up from the basic plan in order to have the podcast encoded at such a high bit rate. So that privilege cost me $10US/month instead of $5US/month. That was a cost that I thought was worth it. Also what if your podcast is being hosted by a network, what file size is reasonable for them to host? Is it acceptable that you have a higher bit rate than the other shows that are hosted there and is it necessary? Personally, I would like to find a happy medium between file size, bit rate and quality. I want the best quality at a reasonable file size. I don’t want my hosting provider to get pissed off that the show is too large. In addition to that fact; the network wants as many people to listen to as many shows as possible. If it is possible that people are “turned off” by a large file size, then that is not for the benefit of the network and I would not do it. In that instance the file size should be smaller at the sacrifice of quality for the benefit of the network and I need to accept that.

As a listener I do not care what size a file is. I have a fast Internet connection and it really does not bother me. I like high quality podcasts but I listen to some that are not of a high quality as far as bit rate because the content is good. So is good quality a cover for shit content? If it is; it is not sustainable long term. So as a listener of podcasts I don’t search for podcasts based on audio quality or file size, and maybe I have just answered my question in part.

Having made these points I will say that some basic editing will improve quality out of sight. I have turned off podcasts because they have not bothered to do this basic editing. They were unlistenable and total shit and they should have thought the same! I wonder if some podcasters even listen to it after they have recorded it. So what do I mean by “basic editing?”

Basic editing in my opinion is:

  • Setting levels before you start, especially if you are recording Skype using a software application. This means setting your levels with enough “headroom” to get loud during a podcast so that you don’t “clip” the recording. And not so soft that you have to amplify it dramatically to get something to work with.
  • Don’t edit the podcast as an MP3, MP3 is a “lossy” format and gets worse and worse in quality every time you re-encode it or open it and save it.
  • Run a compressor on the audio to “smooth” the audio. That is take out the high’s and bring up the lows.
  • Run the compressor a few more times.
  • Normalise” the audio, basically set the zero level. Makes the podcast the same volume and means that the listener isn’t constantly turning their volume up and down.
  • You may need to “amplify” the whole audio after using the compressor and normalising the audio. You don’t want the listener running out of volume because it is too soft!
  • Any added or imported audio needs the above steps.

Believe it or not the above takes the least amount of time in my editing but makes the biggest difference. I do go a step further and edit the actual audio and take out the umms and errs and we always stuff things up and say well we will edit that out. The time is also in the transitions and the mixing of the imported audio, making it all work together (the best that I can). So maybe you can see why as a podcaster I want it to sound as good as I can, I put a lot of effort into both the pre and post production. But is that at the neglect of other issues? Is this basic and advanced editing enough to make it a “quality” podcast?

Please leave a comment and tell me what you think. Tell me if you are a listener or a podcaster. Podcasters, tell me what you encode your podcast at and why. Listeners please answer my questions for me. As I said at the start of this post I really do not know what the right answer is, that’s why I have posed lots of questions. It would be great to get some answers, although I am not sure there is one.

Odeo Respond, Download Link Returns!

As posted yesterday it appeared Odeo had decreased it's functionality of the "send me an Odeo message" by not allowing users to download the mp3 of the left message. Well there has been a great response from Odeo with emails and even a blog comment. All is restored in the Odeo universe.

Odeo Download LinkBiz Stone who works for Odeo left a comment on the Rail yesterday that indicated that the omission of the Download link on the web page was a bug and implied that they were unaware of the problem until I had blogged about it. So great I found a bug! The emails that were recieved were also prompt and promised a resolution. The action by Odeo to resolve the issue has been excellent. When I logged onto my inbox this afternoon, the download link is now present and accounted for. Everyone breath a sigh of relief. I am yet to see if the enclosure in the RSS feed from the "inbox" has been fixed as well but I am assuming that it has.

I commend Odeo staff on their excellent response time and the fact that they responded at all. They could have easily just resolved the problem and pretended that it did not happen. Great work Odeo, we still love you 😉 (In a nice blokey type of way…).

In fact I am not really sure how Biz found my humble blog, and if he is reading this then I wouldn't mind knowing. The other thing that I was curious about was if the staffers at Odeo patrol the BlogOsphere looking for tags and posts regarding Odeo, to see what people are saying and suggesting. I know that one suggestion that I made in the past was implemented, so that was cool.

Thanks Odeo keep up the good work.

FeedReader Now Supports Enclosures

FeedReader Logo_OldI was talking to my brother-in-law tonight and giving him a crash course in RSS feeds and podcasting and just how great the whole thing is. I think I left him sufficiently confused but excited about what it could do for him. That aside I was recommending a feed reader for him to try and I have always recommended FeedReader. I was very surprised to see that it now supports enclosures (and that includes podcasts!).

While I have not used this version which is FeedReader 3.02, I am sure that it is as easy to use as it was for me when I used it. I have used FeedDemon for some time now, one of the main reasons that I switched to FeedDemon was the fact that it is an all-in-one solution. It supports both feeds and lots of different types of enclosures including podcasts and I liked the idea of having it all in the one place. Essentially both these programs do the same thing; in that they now both support enclosures and read news and whatever other feed you wish to subscribe to. But now when I recommend a reader I won’t have to give an explanation as to why you can not get podcasts with it and why you need a program like Juice to do that. This makes FeedReader a very nice no cost alternative for anyone wanting to give RSS a go.

Juice is a very good Podcast aggregator. However I do think that it is not the easiest piece of software to use for a person that is new to RSS or podcasting. Now having the podcasting support in FeedReader means that a user only has to learn to use one program and not two. Both having very different interfaces. The other huge bonus for the end user is that FeedReader is still open source and still free! Which is great news all round in my book. The new version of FeedReader has some other great new and improved features so check it out!

So for my mates that I put onto FeedReader, go and update it to the latest version on the Download Page and shove your podcasts and feeds into it and let me know how easy/hard it is to use. I hope it makes it a lot easier for people to utilize RSS and enjoy podcasts.

What is RSS?

What is a podcast?

What is an aggregator?

Ok, so I have the software where can I go to find some great RSS feeds and podcasts?

That should be enough to get you going I am sure you will start to notice RSS links and feeds and podcasts everywhere now.

Don’t forget to add Rooster’s Rail to your subscriptions and Global Geek Podcast! Here are the RSS feeds for those. Right click and copy the link and paste it to your reader of choice when you have selected to make a new subscription:

Global Geek Podcast 004 is Out Now: Go Get Some Geek

Well I am very happy with the end result of the published podcast. If you have not listened to it before now then please give it a go.

I was very, very peeved that I initially lost two and a half hours worth of editing work. I am not sure what I did in Audacity but I think in blaming myself I am blaming the right person and "thing". So tonight I sat down and started again, from the beginning. Now I am very pleased to be finished. I had a lot of editing and splicing of tracks to do in this one, which was a challenge but well rewarded in the end product. I am leaning heaps as I go.

The one thing that I was absolutely stoked about was the fact that the audio levels were spot on, I had to do very little stuffing around using the compressor. I did normalize the final edit and amplify it and that's it. Setting our levels is always tricky with the methods that we are employing to record as I might have said before. But the attention to detail has been worth it.

One thing that has irritated me is the fact that when I uploaded the podcast tonight the LibSyn player in the top right of the page did not update! So please if you listen to it using this method please either download it, or click the symbol next to the post with "POD" on it. Alternatively the widget here has been updated so that you can listen to it from here! I have shot off an email to LibSyn and await a response from them. I do know though that over the last couple of days they have been working on their servers so this might be the reason. Also because of this, if you can not connect to the website please try in an hour, as LibSyn believe that this is the only length of down-time to expect.

Other than that, enjoy the show!
