PartIICreatingYourOwnAudioPodcastIntroductiontothePodcastingProcess
We
may
divide
the
podcasting
process
into
the
following
steps:
1. Planyourpodcast2. Assemblethehardwareandsoftwareneededtocreateyourpodcast3. Setupapodcastingaccountatawebsitethathostspodcasts4. Recordyourpodcast5. Edityourpodcast6. ConvertyourpodcasttoMP3format7. Publishandpublicizeyourpodcast
Wewillnowlookatthesestepsinmoredetail.
1. PlanningYourPodcastAccordingtoGarrickChowofLynda.com(http://movielibrary.lynda.com/html/modpage.asp?ID=214),
whenplanningapodcastyoushouldconsiderthefollowingfactors:9 WhyamIdoingthis?9 WhattopicscanIspeakonauthoritatively?9 Narrowdownthescopeofthepodcast.9 HowoftenwillIproduceepisodes?
Next,weshouldthinkabouttheformatorstructureforourpodcast.Someissueswemightwishto
considerare:
9 Keeptheformatconsistentforeachepisode.9 Includeabeginning,middle,andendineachepisode.9 Startstrongandendstrong.9 Leadoffeachepisodewithyourstrongesttopic.
Itis
always
agood
idea
to
begin
each
podcast
episode
with
ashort
musical
intro
and
end
it
with
ashortmusicaloutro.Donteventhinkaboutusingcopyrightedmusicwithoutpermission.TheRecordingIndustryofAmericaisextremelyzealousinfindingandsuingindividualstheythinkmightbe
