  1. Making Your Own Podcast Presented by the Science, Technology and Society program

  2. Presenters • Melissa Moon, STS Program Coordinator • Dario Mendoza, STS Research Assistant

  3. What is a podcast? • A podcast is a audio or video file that is distributed over the Internet for listening on mobile media devices or personal computers. • A podcast is basically a web feed of a video or audio file that users may subscribe to.

  4. What is a podcast? • A podcast is typically an .mp3 file. • Each separate podcast is typically referred to as an episode. • A podcast is typically distributed by a url, the feed url, which is expected to be a permanent url. • A user may download episodes individually, or may subscribe to all episodes of a particular podcast. • You would download episodes individually when you are trying out a new podcast and are unsure about whether to subscribe or not.

  5. Subscribing to a podcast • When you have found a podcast that you enjoy, it is best to subscribe to it. • You enter the feed url into a podcatcher which will automatically retrieve new episodes when available. • Podcatchers typically run at all times on your computer. • When a new episode becomes available, the podcatcher will automatically download the episode for you so you may listen to it when you want. • Popular podcatchers include: iPodderX (Mac), iTunes (Mac/Windows), podnova (Mac/Windows), Juice (Mac/Windows)

  7. Revolutionizing entertainment • How is the podcast revolutionary? • It allows the user to select which programs he or she wants to listen to or view. • Select only the content that interests you, as opposed to broadcast programs. • The user can listen or watch when he or she wants to • Podcasts are available any time of the day. • The user can listen or watch where he or she wants to • Anywhere there is a personal computer or wherever you are with your mobile media player. • The user can listen or watch how she wants to • You have complete control over the program: you can fast-forward, rewind or pause at any time. • Any user can create his or her own show. • Any subject, any time.

  8. Popular podcasts • According to Yahoo! Podcasts: • 1. This Week in Tech • 2. NPR: All Songs Considered • 3. Science Friday: Making Science Radioactive • 4. ChinesePod | Learn Mandarin Chinese • 5. Slate Magazine Podcasts • Source:

  10. Creating your own podcast • Anyone can create his or her own show through podcasting. • The user determines everything: the format, the subject, the length, etc…

  11. Two basic components • There are two basic components necessary to create a podcast: • A personal computer • A microphone • This is the best investment you can make for your podcast. • The better the microphone, the better your podcast will sound, which results in better quality. • For more advanced users: One other thing to consider is your soundcard. The better your soundcard, the better the quality of your podcast. A better soundcard can produce better audio and reduce hissing sounds.

  12. Other essentials to the podcast • Headphones • Why headphones and not speakers? • Headphones enable you to hear every nuance of your podcast. They are much more precise than speakers. • The best investment would be over-the-ear headphones. These are better at canceling outside noise.

  13. Choosing a client • You will need a podcasting client that will enable you to create your own podcast. • For Professionals: Adobe Audition 1.5 ($300) • This is for more advanced users. • • Open Source: Audacity • This is the best option for people who are just getting into podcast creation. • Works on Windows, Mac, and Linux. •

  14. Creating your podcast • Open the program, Audacity, that is on the desktop. • First we will need to set some initial settings: • File  Preferences  Audio IO Tab • Set the soundcard for playback and recording. • Under recording setting, change recording to 1 channel (mono). • Quality tab • Leave quality at the same (44100 hz). • Default sample rate: lower to 16 bit. • File Format tab • Want to record uncompressed (WAV microsoft 16 bit PCM) • This will give you the best quality sound. • MP3 Export: drop down to 64 for standard podcast. • You don’t really need any higher quality than this.

  15. Initial procedures • Select Project  New audio track • Drag the audio track box down so it fills most of the Audacity window. • These are the initial tests in order to familiarize yourself with the client: • You need to speak into the microphone in order to figure out how loudly you need to speak • -12 to -16 db is a good range. When you get near 0, your voice will distort.

  16. Recording your podcast • Now you are ready to begin recording your own podcast. • Open a new project (File  New Project) • Open a new audio track (Project  New Audio Track) • Start recording!

  17. Topic ideas • Sports • Politics • Music • Movies • TV Shows • Books • Anything else you can think of!

  18. After you have finished recording: • Some post-production steps: • Reduce noise (Optional) • Record about 15 seconds of silence. • Select this silenced portion of the audio track and go to Effect  Noise removal. • Click ‘Get Noise Profile’. • Then go into Effect and Noise removal again. Use the slider bar to determine how much noise you want removed. • Normalizing (Optional) • Bringing all your audio levels up to the same level. • For example: If you used another source of audio like music. • Select low audio to amplify (want a consistent level across the board). Then select Effect  Amplify. Uncheck the don’t allow clipping box and select ok. • Now you will want to select the entire audio track. Click Effect  Normalize and select ok. • Encoding (Necessary) • Go to File  Export as .mp3. • Choose to save to the desktop. • E-mail to yourself so you have your own copy.

  19. Making your podcast public • There are a variety of ways: • Upload to your personal webspace • Personal website • Blog • Email / Instant Messenger • Podomatic

  20. Podomatic • Go to • Register for an account • Log-in to your account • Select ‘Podcast’ from the menu • Select ‘Post Episode’ from the next menu • Fill out the different fields then click ‘Import’ • Click ‘Browse’, and then select your personal podcast file. Select ‘Use File’. • Now select ‘Publish’. • Podomatic will now give you your own personal url for your podcast. You can now send this link to anyone and distribute your own personal podcast. • Whenever you want to update with new episodes, follow the same procedure.
