Create a Podcast usingAUDACITY
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
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
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”
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)
Fade-In and Fade-Out
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
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
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.
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!
Add your own VOICE
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.
Put it all together “Un-Mute” all tracks Use the “Time Shift” tool Click and drag your intro music to the
beginning of your podcast Click and drag “Ode to a Grecian Urn” and its
background music Line these two up just after the intro music
Again use the Time Shift tool to drag the voice recording to line up after the “Ode”
Listen to you transitions, make adjustments where necessary
