Edit a Podcast Trailer
Edit a short podcast trailer using simple audio tools: record a script, trim clips, add music and sound effects to create a polished preview.
Step-by-step guide to edit a podcast trailer
Step 1
Read your script out loud once to practice the words and decide where to pause.
Step 2
Open your audio editing software and make a new project file.
Step 3
Record a 3 second sound check and play it back to hear how you sound.
Step 4
Turn the microphone input volume up or down so the test sounds clear and not too loud.
Step 5
Record your script in short clips one sentence or one paragraph at a time.
Step 6
Play each clip and delete any takes you do not like.
Step 7
Trim the beginning and end of each clip to remove silence and mouth noises.
Step 8
Import your music file into the project.
Step 9
Create a new track and place the music track under your voice clips on the timeline.
Step 10
Lower the music track volume until your voice is easy to hear over the music.
Step 11
Import your sound effect files into the project.
Step 12
Drag each sound effect to the spot in the timeline where it fits the story.
Step 13
Add short fades to the start and end of the music and to any sound effects that are too abrupt.
Step 14
Export the whole project as an MP3 or WAV file and name it PodcastTrailer_YourName.
Step 15
Upload and share your finished podcast trailer on DIY.org.

Help!?
What can we use if we don't have a microphone or audio editing software?
Use a smartphone's built-in mic or a headset mic for the 3-second sound check and recording, and use free editors like Audacity or browser-based editors to make a new project, import music and sound effects, and export an MP3/WAV.
My voice is getting drowned out by the music — what should I check?
Run the 3-second sound check to set mic input volume and then lower the music track volume under your voice clips and add short fades so the voice stays easy to hear over the music.
How can I adapt this activity for younger or older kids?
For younger children, have an adult help record the whole script in a few clips and import pre-chosen music/sound effects to simplify trimming, while older kids can record sentence-by-sentence, do precise trimming and multi-track mixing, and export PodcastTrailer_YourName before uploading.
How can we make the trailer more unique or professional?
Create a custom intro/outro voiceover, import or make original sound effects and drag them to timeline spots with short fades, add additional music tracks for different sections, then export the final MP3/WAV named PodcastTrailer_YourName to share on DIY.org.
