Internet Radio Because content is stored in your computer’s

memory, you can listen/ view whenever you like You can “fast forward” content as you see fit

computer

What this presentation will do for you We are going to get familiar with Audacity

Free software to record and edit audio files We will edit and optimize a sound file We will record a sample piece of audio

We are going to upload our sound file to podomatic.com Pod-O-Matic is a free site that will store your sound

file Pod-O-Matic provides an RSS feed that your

students can use to subscribe to your podcast

Audacity This is Audio Editing software Audacity is used to create multi-tracked sound

files Each audio “take” is represented by a graphic

“waveform” Audacity can also be used to mix songs

together as a Mash-Up Audacity can be used to make custom

ringtones for most phones Audacity can be used to make a custom radio

show If you have additional equipment, you can

even use Audacity to record and mix a song

Page 9: Podcasting and audio editing

AudacityWe are going to use Audacity to do the

following: Select and fade intro music for a podcast Edit out unwanted pieces from an audio file. Add background music Record your voice Then, we are going to put together several

audio clips into a single audio file

Audacity Importing Tracks To import a new audio clip to work on,

simply drag and drop from your file directory (windows explorer or mac finder)to the audacity workspace

Page 21: Podcasting and audio editing

Select and trim a track Import “yellow.mp3”

You can pick- Coldplay (Yellow), Yellow (Oh yeah) or SAWA (Yellow)

Preview your song to find your ideal introduction music You may want to zoom-in

Click and Drag to highlight your selection When a piece of audio is highlighted, Audacity will play only the

highlighted audio Push the Space-Bar (or press the play button) to play your

selection Delete portions the track that you don’t need

click the Trim Outside Selection tool . Everything but your selected area will disappear. 

Don’t worry, you are not deleting your original sound file! Leave some audio at the end of your file for a “fade out”

Page 22: Podcasting and audio editing

Fade-In and Fade-Out Use the Envelope Tool Click the top edge of your audio wave where

you want the fade to begin Watch the shape of the wave! You don’t want to

“pinch” Click and Drag the top edge of the wave

where you want your fade to end. As you drag the edge inward, you will see

your track “fade-out” Use a similar procedure to make a “Fade-In” (if

you like)

Page 23: Podcasting and audio editing

Fade-In and Fade-Out

Page 24: Podcasting and audio editing

Editing spoken word “Mute” your intro music Import “Ode Urn.wav” Here is the text as it should be read:

Fair youth, beneath the trees, thou canst not leaveThy song, nor ever can those trees be bare; Bold Lover, never, never canst thou kiss, Though winning near the goal;�yet, do not grieve; She cannot fade, though thou hast not thy bliss

Use Audacity to delete unwanted parts to create a “good read” of this stanza

Page 25: Podcasting and audio editing

Editing spoken wordFair youth, beneath the trees, thou canst not leaveThy song, nor ever can those trees be bare; Bold Lover, never, never canst thou kiss, Though winning near the goal;�yet, do not grieve; She cannot fade, though thou hast not thy bliss

Using the “Selection Tool” highlight unwanted portions of the audio

Zoom In if you are unsure about what to select Push the delete key Don’t forget, you can “undo” if you make a mistake When you are done, select the entire piece, and copy

and paste another stanza at the end of the reading

Page 26: Podcasting and audio editing

Mixing background music After you have a good reading of “Ode to a

Grecian Urn” you can add background music Import either “Forest- Satori” or “A Forest- The

Cure” Use the faders (volume control) located on the

left of your wave form to adjust your background music choice to the appropriate volume level.

Page 27: Podcasting and audio editing

Add your own VOICE Most computers will have the built-in

microphone enabled to record audio. All you need to do is press ‘Record” Mute “Ode to a Grecian Urn” and you “Forest”

music Press the Record button Wait 5 seconds Start talking! If you make a mistake, don’t stop recording.

Just start over again at an appropriate place. Edit your file when you are finished!

Page 29: Podcasting and audio editing

Need something to podcast? `Twas brillig, and the slithy toves;  Did gyre and gimble in the wabe:

All mimsy were the borogoves,  And the mome raths outgrabe

"Beware the Jabberwock, my son!  The jaws that bite, the claws that catch!Beware the Jubjub bird, and shun  The frumious Bandersnatch!"

He took his vorpal sword in hand:  Long time the manxome foe he sought --So rested he by the Tumtum tree,  And stood awhile in thought.

And, as in uffish thought he stood,  The Jabberwock, with eyes of flame,Came whiffling through the tulgey wood,  And burbled as it came!

One, two! One, two! And through and through  The vorpal blade went snicker-snack!He left it dead, and with its head  He went galumphing back.

"And, has thou slain the Jabberwock?  Come to my arms, my beamish boy!O frabjous day! Callooh! Callay!’  He chortled in his joy.
