Audio Blocks Overview

Insert audio clips into your show with Audio Blocks

Audio Blocks are the clips of audio that are dynamically inserted into your episodes through the use of Insertion Points. Depending on your plan, you can place default and custom Audio Blocks all throughout your podcast.

This article dives deeper into where to find Audio Blocks, what exactly they are, and how to best use them to your advantage.

What are Audio Blocks?

Audio Blocks are the clips of audio that are played at the exact timestamp an Insertion Point is placed. 

You may notice on the Dynamic Insertion page a couple of already-existing Audio Blocks. We automatically create the Default Ad Block and Default Cross Promotion Block when you opt-in to RAP and the Cross-Promotions feature respectively:

Dynamically insert audio clips into your podcast episodes with RedCircle's Audio Blocks and Insertion Points

The Default Ad Block plays up to 2 RAP ads (Programmatic and Host-Read) back-to-back depending on inventory availability.

The Default Cross Promotion Block plays up to 2 Cross-Promotional ads back-to-back depending on active campaigns. For example, if you only have one Cross-Promotion going on, then that promotional ad only runs once.

It’s not possible to edit any aspect of these two default Audio Blocks.

Members on the Growth Plan or higher have the ability to create Custom Audio Blocks for things like intros/outros, special announcements, off-platform ad campaigns, and more. More on that later!


How Audio Blocks work with Insertion Points

Audio Blocks and Insertion Points are intimately tied. They can’t really work without the other. The most typical use of Audio Blocks and Insertion Points is for ads procured through RAP (the RedCircle Ad Platform).

For example, let’s say you opted-in to RAP and are ready to start monetizing. You would first place Insertion Points at specific spots within your episode. Next, you would assign the Default Ad Block to one or more of those recently-placed Insertion Points. 

Every time someone tunes in to your show, our system checks whether or not there’s an Insertion Point. If the Insertion Point is assigned an Audio Block, then we dynamically insert that audio for that listener.

For example, if you placed a Pre-Roll Insertion Point at the 00:01:00 (one minute) timestamp and assigned the Default Ad Block, then the listener should hear either a Programmatic (pre-recorded) or a Host-Read ad at that exact timestamp. 

We dynamically insert based on your active campaigns and available inventory. (See our Insertion Points Help article for a more detailed look at how this works.)

Whatever Audio Block you assign to an Insertion Point plays at the exact moment the Insertion Point is placed in your episode.


How to Create Custom Audio Blocks

If you’re a member on the Growth Plan or higher, then you can create custom Audio Blocks for any audio you want to dynamically insert in your episode(s).

Click on the gray Audio Blocks box near the top-right area of the Dynamic Insertion page:

Create custom Audio Blocks to dynamically insert audio clips into your podcast

Then click on the red New Audio Block link near the top-right corner:

Create custom Audio Blocks to dynamically insert audio clips into your podcast

Enter the name of your custom Audio Block and click the red Next button near the bottom-right corner of the pop-up screen.

Configuring Audio Blocks

The next step is to configure your Audio Block. On this page, you can determine the ‘play style’ and ‘play up to functions of your Audio Block. 

A play style controls the order in which 2 or more audio clips are played within that block. You can set it up to be “in order”, meaning the clips are played sequentially until the ‘play up to’ number is reached. Or, you can set it to “random”, meaning the clips are played in a totally random order until the ‘play up to’ number is reached.

‘Play up to’ refers to the number of audio clips that are played within the Audio Block. You can set it for 1, 2, or more. We don’t recommend going above 3. You don’t want to overwhelm your listeners with a ton of back-to-back ads and/or promotional clips!

Choose how many audio clips and in what sort of order they play in your podcast

Don’t forget to add your audio by clicking on the red and white Add Audio button. You can choose between an audio file from your computer or a cross-promotion. For cross-promotions, we’ll pull from the available inventory based on your active cross-promotional campaigns. (Similar to RAP ads!) 

Click the red Next button after selecting your audio and deciding your ‘play style’ and ‘play up to’ choices.

Assign Audio Blocks to Insertion Points

The final step is to assign the Audio Block to one or more of the episodes of your podcast:

Assign custom audio blocks to your insertion points in order to dynamically insert audio clips in your podcast


Be sure to click on the red Submit button to finalize your Insertion Point selection and create the custom Audio Block.


Bulk Assigning Audio Blocks

As seen above, you can assign an Audio Block (both custom and default) to multiple Insertion Points all at once. This is known as “bulk assigning”. Utilizing this feature saves you a ton of time when creating and editing Audio Blocks.

You can get to this screen either by creating a custom Audio Block, as shown above, or by clicking the 3 dots (...) next to the title of the Audio Block on the Dynamic Insertion page and selecting Assign Insertion Points:

Bulk assign Audio Blocks to your Insertion Points

A module then pops up where you can select your show. You can assign the Audio Block to already-existing Insertion Points after selecting your show.

You may notice drop-downs with “Pre-Roll”, “Mid-Roll”, and “Post-Roll” titles. Clicking on those drop-downs brings up a list of options.

Assign Audio Blocks to pre-roll, mid-roll, or post-roll Insertion Points

See below for what each option means:

  • First: This refers to the very first Insertion Point in the episode. So, if you have two Insertion Points in Pre-Roll, this refers to the one that's in the first position.
  • First Available: This refers to the first Insertion Point available in the episode. So, say you have one Insertion Point at 00:00:00 and another Insertion Point at 00:01:02. If the Insertion Point at 00:00:00 already has an Audio Block assigned to it, then clicking First Available would assign to it the 00:01:02 spot.
  • Last: This refers to the very last Insertion Point in the episode.
  • Last Available: Similar to First Available, clicking this assigns the Audio Block to the last Insertion Point that's available/open. So, say you have one Insertion Point at 00:30:00 and another at 00:28:10. If the Insertion Point at 00:30:00 already has an Audio Block assigned to it, then clicking Last Available would assign to it the 00:28:10 spot.
  • All: This option assigns the Audio Block to all Insertion Points in that audio area in every episode. For example, if you click ‘All’ in the Pre-Roll drop-down, then all Insertion Points in the Pre-Roll spot will be assigned that Audio Block.
  • Unassign: This option unassigns the Audio Block from all Insertion Points in that audio area in every episode. For example, if you click Unassign in the Pre-Roll drop-down, then all Insertion Points in the Pre-Roll spot are removed from that Audio Block.

As for the checkmark boxes, the faint red line indicates that an Audio Block is already assigned to it. So, if you click All, then it overwrites the Audio Block that is already assigned. However, if you click First Available, then it assigns the Audio Block to the first available spot.
