Add a podcast intro and outro
and save the episode as one file.
Line up your podcast intro and outro around the episode, listen to the joins and download one finished WAV.
If you open and close every episode with the same clips, there’s no need to rebuild a timeline each week. The audio joiner plays files back to back and takes up to 20 minutes of audio in total, so it suits short episodes, trailers and bonus segments better than a two-hour interview. Get the music and voice inside your intro and outro sounding right first. The joiner puts finished clips end to end; it won’t lay your voice over a music bed for you.
Line up the intro, episode and outro
- Pick all three files at once. Open the audio joiner, select Choose files and choose your intro, the episode and your outro together.
- Get the order right. Check the numbered list and use Up and Down until it reads intro, episode, outro. If the wrong file slipped in, click Remove next to it.
- Start with no crossfade. Leave Crossfade at each join (seconds) at 0 so each clip starts the instant the last one ends. Any higher number overlaps the clips at every join.
- Press Play. Listen across the first join and make sure your opening line isn’t buried under the tail of the intro music.
- Click Download WAV. The file saves as joined-audio.wav, so rename it with the episode number and title before it gets lost in your downloads.
Decide how each join should sound
Most intros end with a bit of ringing music. Decide whether it should finish before you start talking or play under your first sentence. If you jump straight in with “Welcome back,” a join at 0 keeps the music and your voice exactly as you made them.
A crossfade fades the next clip in as well as fading the last one out. If you start talking in the episode’s very first second, a crossfade will bring that first word in quietly. Leave a breath of room at the start of the episode, or keep the setting at 0.
One setting covers every join. If the intro wants a soft overlap but the outro needs a clean cut, build that overlap in your editor, export it, and join the finished files at 0.
Make sure the clips sit at the same volume
Play the end of the intro and the first sentence of the episode without touching your volume. Do the same at the outro. A punchy intro that sounds great on its own can feel like a shout next to a relaxed conversation.
If one clip is too loud or too quiet overall, run it through the audio normalizer before you join. Set a target loudness, download the adjusted WAV and use that version in the joiner. Giving all three clips the same target is a quick way to get them close. Then listen to both joins again.
Check the file you’ll actually publish
Open the downloaded WAV in your usual player. Listen to the opening, then skip to the last minute and make sure the outro comes in after your sign-off instead of cutting it short. Keep this WAV with the episode’s raw recordings, and make whatever file format your podcast host asks for from it.
