Sorry for the epic fail in class. Congratulations to those of you who have already posted, in spite of this.
What you need
You’ll need some hardware and software to do this. If you have a recent laptop, you probably already have a built-in mic. This may work–some built-in mics are better than others–but the single most important thing you can do to improve the audio quality is to improve your mic. The lectures are recorded using a good headset mic, but still are not great quality. I recently have a Snowflake that I’m fairly happy with, but it’s not cheap. (Or, rather, it is cheap as microphones go–if you plan on doing some podcasting or other computer-based recording, it’s not bad at all–but it’s more expensive than most decent headsets.) For the purposes of this assignment alone, you can probably make use of your built-in mic, if you have one, but try to get close, without speaking (blowing) directly into it. Also, try to maintain the same distance from the mic throughout.
You will also need software. If you have a recent Mac, you are likely to have Garage Band already installed. Go ahead and use it, it’s a great product, and tutorials abound.
If not, I’m assuming you don’t have a recording program. You may–if you’ve done video before, you may have a copy of Protools already on your system. Or, if you’ve purchased the Production Premium suite from Adobe, you have a copy of Soundbooth, which is really overkill for what we are doing. I don’t have experience with Soundbooth, but you are welcome to give it a run.
Most podcasters use a piece of free, open source software called Audacity. Audacity is great–relatively easy to work with and powerful. And it’s free. There is a small hiccup. Because the MP3 format is not an open format, you have to actually install an MP3 encoder in addition to the Audacity software. Actually, if you want to publish in the free alternative to MP3, called OGG (ogg vorbis), that’s great with me. Otherwise, you’ll need to download the LAME encoder to create the MP3. This is the whole tortured AR-15 full auto thing I was talking about.
Mic: check. Software: check. On to recording.
Wait, you didn’t say check? If you have no mic, and want to be a little adventurous/tame, you might give one of the podcast-by-phone options a try. You can literally “phone it in.” There are a number of providers: Gcast, Phonecasting, Slapcast, Talkshoe, Hipcast, Yodio, and Gabcast, among others. If you go this route, let me know how it works out–I haven’t had much experience with them (I’ve been interviewed via a phone for podcasts, but never actually did the podcast).
Produce
I would recommend that you use a script. If you make a mistake, just wait a few seconds (so you can easily find it) and start again, you can edit out the error.
You want to keep the audio file to a reasonable size. Let’s say less than 8 Mb. If yours is bigger than that, cut some of it out. (No, not really, you can follow directions here for decreasing the bitrate of your mp3.) The smaller the file the better–and the less time it will take to upload. WAVs are great, but take up substantially more space. You may have already touched on lossy and lossless compression in 502–the same goes here. MP3 is a lossy algorithm, and a good choice for the web.
If you want, you can edit the ID tags, either in Audacity or in Winamp (or whatever player you use that will allow you to do this, or even just in Windows properties for Vista).
Hosting / Uploading
This should be the easiest part, but unlike a good cooking show host, I didn’t try the recipe first before inflicting it on you. Basically, I failed to click the “File URL” button on the “Link to” line. If I do that, it works fine. I blame the lack of caffeine!
There are, again, other hosting options, from the Internet Archive to Odeo, but the easiest (if not most usable!) way is to just click on the media upload on Wordpress, but remember to click the “File URL” button.
Finally, I ended up scrapping this reading, but encourage you to pursue it on your own, if you are interested in the audio side of things. It is a short graphic-format (comic book!) tracing how Ira Glass puts together “This American Life,” called Radio: An illustrated guide.
