AUDIO INSERTION

Keep every episode promoting your latest campaign

Swap a host-read promo, refresh a call to action, or push a launch or event announcement across your entire back catalog. No re-editing, no re-uploading, no waiting on a new episode to carry your message.

Changes roll out across Apple, Spotify, and every other listening app automatically.

Update. Target. Measure.

Dynamically insert audio into your episode catalog

Refresh a promo across every episode, target the right shows, and retire a message the moment a campaign ends. Update the audio listeners hear without re-editing or re-uploading a single file.

Promo refresh

Put your current campaign in every episode

Your best episodes keep getting downloads for years. Refresh the promo or call to action across all of them at once, so a listener who finds a two-year-old episode still hears what you want them to hear today.

Targeted insertion

Run the right message on the right episodes

Choose exactly which episodes get audio dynamically inserted, schedule when it starts, and preview before it goes live. Add a pre-roll promo to your top five episodes, a post-roll to one season, or company disclaimers to your entire catalog.

Always current

Retire an audio promotion the moment a campaign ends

Swap or remove audio as soon as the messaging or offer changes, so nothing outdated keeps running. A status view shows what is active, paused, or drafted, keeping the right call to action live and the expired ones gone.

Talk to our team →
01 Can I add or change audio on episodes I already published?
Yes. Insert or swap pre-roll and post-roll audio on any published episode with no re-editing and no re-uploading. The change applies the next time the episode is served, so your back catalog stays on message without touching the original files.
02 How fast do changes reach Apple, Spotify, and other apps?
Make the change once and it applies across every listening app automatically, with no need to re-publish or push a new episode. Exact timing depends on how often each app refreshes your feed, so changes appear as those platforms update on their normal schedule.
03 Can I target specific episodes instead of the whole catalog?
Yes. Choose the exact episodes to receive an insertion, preview the audio before it goes live, and easily launch or save as a draft when you're ready.
04 Does CoHost support pre-roll and post-roll insertion?
Yes. Add audio to the start or end of an episode, and bulk-apply one message across as many episodes as you'd like in a single action. Clear labels track each insertion's purpose, placement, and status.
05 Can I swap, pause, or remove a promo after it goes live?
Yes. Replace, pause, or delete a promo the moment a campaign changes. A status view shows what is active, paused, or in draft so the right call to action is always running and nothing outdated lingers in your feed.
