Tools To Get You Podcasting Part II

Getting started is very inexpensive: entry level might include an $80 USB microphone, a computer and some free software. Want to get fancy? Buy a couple of good-quality microphones, a phone hookup, commercial software, and a soundboard to blend the different voices.

Fortunately, you don’t need specialized digital recording software or proprietary hardware to podcast. In fact, you can probably use whatever digital audio software and hardware you already have. Audacity is a great free, open source digital audio application that is available on several platforms: Linux, Mac OS X, Windows and other operating systems. It is both an audio editor and digital recorder that can record live audio, convert tapes and records into digital recordings or CDs, edit Ogg Vorbis, MP3, and WAV sound files, cut, copy, splice, and mix sounds together, and change the speed or pitch of a recording. You can do shows live, you or you can drag and drop the music files into the program and arrange them. Programs like Audacity are also called open source software, because their source code is available for anyone to study or use. There are thousands of other free and open source programs, including the Mozilla Web browser, the office suite, and all the Linux-based operating systems. Go to for more info.

Other free tools include VOP (voice over IP) software such as X-Lite from CounterPath at and Gizmo, a free, open-source application from Gizmo Project at that can record phone conversations digitally. For budget-minded commercial products, there are many to recommend. ePodcast Creator lets you record, edit, create an RSS feed and upload your podcast; and is available from Industrial Audio Software PlayPod by IGG Software is a powerful, easy to use Mac OS X podcast client that allows you to start browsing thousands of free radio shows, and news shows at Juice is a free application that allows you listen to podcasts.

Digital Audio Recorders: Hardware Alternatives
New generations of dedicated digital audio recorders have entered the market offering great hardware alternatives for podcasting with professional level quality.

Marantz Professional at has the PMD660 portable solid state recorder that is small enough to fit in the palm of your hand but has features that make more expensive, full-sized field recorders green with envy. It runs for hours on just four AA batteries. It records on Compact Flash media cards which you can find at any discount store and will store more than 35 hours of mp3 mono audio on a single 1 gigabyte flash card and over 3 hours of pristine, uncompressed, 16-bit .wav files. Editing can be done right there in the field with a choice of two editing modes or you can use your favorite audio editing software by transferring files to your computer via the built-in USB port. I particularly like that it can use two XLR mic connections with +48v phantom power, or its two built-in condenser mics for true stereo recordings.

M-Audio at offers a rugged high-fidelity mobile 2-channel digital recorder that records WAV and MP3 files to CompactFlash or microdrives at 24-bit 96 KHz quality. A 1 GB CompactFlash card can hold approximately 100 minutes of uncompressed

CD-quality 16-bit stereo 44.1. KHz WAV files. Powered by a lithium-ion battery the unit can recharge via the computer’s USB connection or included USB power adapter.

EDIROL by Roland at offers an R-09 digital recorder which records in 24-bit uncompressed audio with a choice of 44.1 or 48 Hz sample rates. It records and plays back in MP3 format as well up to 320 kbps. It offers built-in stereo recording with the onboard stereo condenser microphone, or 1/8″ Mic and Line inputs for external mics components. It records to an SD card (P64 MB card included), and uses standard AA alkaline or rechargeable batteries that can offer approx. 6 hours of recording time. The unit is pocket-sized, and features simple, one-hand operation.

Closing Comments
Some podcasts are simply recorded lectures, classroom noise included. Others are more sophisticated audio and video presentations. Podcasting seems to have rekindled an interest in the use of audio in education. And with the use of laptops and other portable devices, digital recording is possible everywhere. And new audio software is easy to use and at reasonably priced. This is the result of the podcasting/digital audio revolution. The type of podcast you want to create should dictate the production and technical resources you chose to use. Digital audio is well within the reach of teachers and students. For example, Tim Thompson and Roget Pontbriand at Palm Beach Atlantic University in West Palm Beach, Florida have integrated podcasting with the use of Sawbills to teach music theory and arranging concepts in the curriculum.
