In the field "Number of ad markers set", you can specify the number of ad markers that are automatically set when a new episode is uploaded. The prerequisite for this is that you have previously activated the function of automatic setting of advertising markers. How this works is explained here: Automatically set DAI markers

The selected number of markers is evenly distributed over the audio file. Example: You set 3 markers to be set automatically and upload a new episode with 8 minutes length. In this case the markers will be set at the positions minute 02:00, minute 04:00 and minute 06:00.
