podcast Mid-roll ads wordpress

Everything is possible in WordPress ??

These requirements are quite specific though, so if this functionality is not available in the previous podcast search I directed you to, you may want to consider hiring a developer.
If this is something that you are interested in, you can post at https://jobs.wordpress.net

i need to know the method to do it myself even if it’s required some codes ??

While someone may come along who is willing to help you write the code for this, it is unlikely, as it is outside of the scope of the assistance provided on these forums.

All the best.

thank you and im not asking for the code im just asking for a method and keywords to develop this

It isn’t simply a matter of linking you to a page with an existing WordPress hook or filter.
Creating the method is part of development (often more time-consuming than writing the actual code).
As I have explained, extensive development assistance is outside of the scope of these forums.
