What is Podcasting ?

• An audio recording posted online, much like a short radio show.

• Think of a podcast as a radio show. Each show consists of a series of individual episodes that you can listen to how you want — on your PC, using your MP3 player, or with just a web browser.

Definition of podcasting

• Podcasting is a term used to describe a collection of technologies for automatically distributing audio programs over the Internet using a publisher/subscriber model. It differs from earlier online delivery of audio because it automatically transfers the digital media files to the user’s computer for later use.

http://en.wikipedia.org/wiki/Podcasting



Podcasting

• “Podcasting” combines two words: “iPod” and “broadcasting”.

• You don’t need an iPod to listen to a podcast! Any PC will be fine!

• Alternative terms would be “audio blog” or “audioblogging”

• “Personal On-Demand” & broadcasting, giving: POD-casting

Podcasting - What It Is

• A podcast is really just an mp3 audio file that is distributed via an RSS feed (by linking the mp3 file to a blog posting or to a web page).

• Current “podcatching” software, such as iTunes, allows the user to subscribe to an RSS feed; the software will automatically download new podcasts when they become available.

Podcasting – The Listener

• Subscribes to the RSS feed for the blog using “podcatching” software (such as iTunes) ONE TIME ONLY

• New podcasts are automatically downloaded to the user’s PC – and can be played on the computer

• The mp3 files can be “synched” to a portable mp3 player, such as an iPod, for anytime, anyplace listening – mobile learning – “m-learning”.

• Emerging Technologies of the past– Portable phones once niche players in

telecommunications– Hard to use– Cumbersome– Expensive

• Now considered one of the three things everybody has– Wallet/purse– Keys– Portable phone

• Continuing to change face of society, this tech is still emerging

Emerging Technology

Podcasting & Emerging Technology

• Podcasting is a subset of RSS which is a subset of Emerging Technology

• Podcasting uses RSS v. 2.0– Enclosures– Also includes videocasting– XML based– Download based– Not dependent on high bandwidth– Dependant on relatively pervasive connectivity

• Technically it is pull technology– Push / pull convergence– Subscription required– Has push characteristics– “Long tail” technology– Infinite number of channels!

Recording the Podcast

• we recommend using Adobe Audition 1.5 or above• If it’s primarily speech:

– record at 32, 56 or 64kbps– 44.1 KHz, Mono or Joint Stereo– MP3 or AAC

• If it’s primarily music:– Record at 64kbps or above– 44.1 KHz, Joint Stereo– MP3 or AAC+

• Name the audio file– sequential – (or) Date sensitiveness

Editing the Podcast

• Any good multi-track editor would work– Adobe Audition 1.5 or above– Samplitude– ProTools– Sonar– Sound Forge– Nuendo– Cubase– Freeware

• Audacity (audacity.sourceforge.net)• Ardour (www.ardour.org) for Mac / Linux

Polishing the Podcast

• Clean up audio – reducing background hiss and other noises, remove clicks and pops.

• Music Loops (if needed)– easily add intro, background, and transitional music to your podcast

• Use Multitrack editing– Edit each track in a way most ideal for its audio characteristics– Cleanly remove unneeded audio segments, and add or delete silence

to smooth dialog sequences– Dub new narration for existing audio to a new track

• Audio Processing– Use the compression and hard limiting features to make dialog

clearer and to smooth out unwanted differences in volume– Add reverb to simulate various acoustic environments

• Timing adjustments– Stretch & compress audio duration to fit length

Polishing the Podcast IIAdobe Audition 1.5 Processing

• Audio Processing– Effects > Amplitude > Hard Limiting

• Limit Max Amplitude to -.2 or -.1 • Boost Input by 6 or 7 dB
