How To Podcast Tutorials
How To Podcast with the Gear You Own - by Todd Cochrane

Personally, I have found that there are a lot of different ways to podcast -- depending on your interests and goals in podcasting. The podcast rig that I show below, is one way to do it. (Since the photos below were taken, I have added a Macintosh Mini computer and a Tapco Squeez compressor, and I have purchased a Zoom H4 portable recorder -- very cool device that could be all I really need to podcast!) You can get by with a lot less equipment, and many podcasters purchase a lot more in their goal for high production quality.

Anyway, this link is to a very comprehensive and readable, and free, website that covers most everything that you might want to consider in starting or improving your podcast. Just remember that you can vary considerably from what any podcaster tells you about how to podcast.

FindSounds - Search the Web for Sounds: "Welcome to, a free site where you can search the Web for sound effects and musical instrument samples."

Someone at the eLearning Institute Workshop asked me about finding free sound clips online. The FindSounds search engine should do the trick.

My Podcasting Steps

These are the steps that I go through to record and post my podcasts. This is a post-processing intensive approach. Using programs like Castblaster, other podcasters produce more of a traditional "radio" show without any post-processing.
  1. Prepare Intro, Outro, Transitions, Sponsors (optional)
    1. Text
    2. Voice overs
    3. Music
    4. Sponsor ads

      1. Creative Commons copyright

  2. Prepare Material
    1. Lecture Notes
    2. Contemporary Events
      1. Email Lists
      2. RSS Readers
      3. Blog This (Firefox extension)
      4. Google Notebook

  3. Set Audio Levels
    1. Volume
    2. Equalizer (on mixer)
    3. (Compression, Gate and other, if available)

  4. Set Recording Rate
    1. 22050Hz sample rate and 32-bit float format (in Audacity)

  5. Record and Save Podcast

  6. Post Processing in Audacity
    1. Leveler
    2. Normalize
    3. Compression
    4. Leveler
    5. Amplify

My Current Podcasting Setup

This is my current home podcasting set up:

The computer is an old 300 MGhz PC with a 10GB hard drive that is on load from my department. It does not record well (drops words) and I am planning to replace it soon! [The vertical white stick thing is an antenna booster for the wireless Internet card that I installed on the computer.]

There are two mice on the table. The sliver mouse is the Thanko Silent Mouse ($35 from I bought is because I got tired of editing out mouse clicks from my podcasts. Works great.

The microphone is an Audio-Technica AT 2020 ($85 on eBay). The microphone requires a 48v phantom power supply.

I think I paid about $25 for the mic stand and about $15 for the pop screen at Arizona Music Pro.

Just below the microphone in the photo below is a Tapco Mix 60 mixer, which also provides phantom power to the microphone ($60). A "balanced" (3 plug) microphone cable connects the Tapco mixer to the AT 2020 microphone. only use one of the inputs, although you can have four to six (depending on the configuration).

The gray and black rectangular box next to the lap is the Edirol UA-1EX. I originally bought this for my laptop, based on comments that laptops have lousy sound cards. However, I found this it resolved the "latency" problem that I had with Audacity (the audio recording and editing freeware program that I use). Latency is the delay between when you speak and when the sound is received in the headphones. I could not use headphones while podcasting until I got the Edirol UA-1EX.

There is a line splitter coming out of the "phones" jack of the Tapco mixer. One line goes into the Edirol, and the other can be connected to an mp3 recorder to create a backup recording. I use an iRiver IFP 890. I only do a backup when recording interviews.

A very simple headset ($1 at the Dollar Tree) is connected to the Edirol so I can monitor the sound as I am recording it.

- iRiver 890 mp3 player/recorder - for backups and sound seeing audio ($45 on eBay)
- SP-TFB-2 - In-Ear Binaural Microphones
and sound seeing audio (, $69)
- Logitec 250 USB Noise-canceling Headset (used on laptop when traveling)
- Tapco Squeez SQ2compressor ($99 - resulted in a great improvement to my sound! - the gate feature pretty much removed the dog and minor house noises)
- Zoom H4 Recorder ($299 - bought for a research project, but also used for podcasting)
- MacMini and an old LCD monitor - replaced the ancient PC in the photo - nice and quiet, and small

The Microphone is connected to the Mixer usine the Balanced audio cable. An unbalanced cable goes from the headphone jack on the Mixer to the Line In jack on the Edirol external audio interface. The Edirol has a USB wire coming out of it that plugs into the computer. I have a split attached to the headphone jack on the Edirol, to which I have the headphones and the iRiver attached.

Podcasting at the UA Learning Technologies Center

Podcasting at the UA Learning Technologies Center:

How Can UA Departments Use Podcasting?

Academic and administrative departments can use this inexpensive resource to connect with students and alumni here at the UA or geographically dispersed across the Internet. Provide weekly podcasts about such things as departmental news, events, professional and scholarly topics, student activities and faculty research. Use it as a marketing tool to set your department apart from others in students' minds. LTC staff are happy to get you started. If your department or college is unable to support you, the LTC will be glad to.

Currently our “blog” isn’t so much of one as the podcasting page is a static page in AFS space until we decide where to host the wordpress version, which is very much still under develpoment. We are looking forward to having a much more dynamic page but for now we are at least out there. - Mansfield University of Pennsylvania - Mansfield University of Pennsylvania:
