## What is an audio podcast?
An informative or entertaining audio piece that is circulated on the web. Podcasts mix voice and music and are usually produced by individuals or amateur, non-commerical groups with modest technology. They can be listened to on the PC or mobile device or by visiting a website; but many use I-Tunes to subscribe to the feed and automatically download new material to their I-pods. Some years ago, Podcastalley.com listed 39,000 podcasts with 2.5 million episodes. More recently, radio networks like [NPR](http://www.npr.org/podcasts/), [PRI](http://www.pri.org/podcasts-program) and [BBC](http://www.bbc.co.uk/podcasts) “professionalized” podcasting; here are some of the [best professional podcasts](http://www.makeuseof.com/tag/best-podcasts-2015-recommended-makeuseof/).
## How is it created and shared? There are four major steps
1. planning 1. recording 1. editing 1. “casting” (publishing by uploading and linking via a blog)
## Recording (How to / practice)
* Use a portable digital recorder or a GOOD microphone. The microphone on your laptop is not good! * Do a test recording. Listen for background noise, popped 'p's, etc. * Make sure your recording *level is high*. (It is possible to record voice with an excessive level but it's very uncommon. Usually people make the opposite mistake, and doing so may require you to repeat the recording! Volume is proportional to distance from the sound source; singers and instrumentalists learn to be close to the microphone.) * Save audio files in a lossless format (WAV)
## The Podcast Process
1. Choose a topic / subject/ purpose. 1. Planning a podcast - choose a format, such as interview or audio-essay 1. Prepare the interview (ex. talk to a classmate about teaching and technology) Or script an essay 1. Record the interview and/or essay 1. Log the interview if you chose that 1. Script and record appropriate narration (at least an introduction and out-tro) 1. Select and prepare background sound, including music 1. Use “audacity” to mix the tracks into a 2-5 minute podcast. 1. Listen, revise, listen, edit, listen, export to MP3.
