For the audio of a show/episode, we recommend ISO/IEC 11172-3 MPEG-1 Part 3 (MP3) audio files with bitrates between 96 and 320 Kbps are supported.
A maximum duration of 12 hours (roughly 2GB @ 320 Kbps) is supported.
If you encounter an error, it may be that the submitted audio file format is unsupported. Please update the feed with an acceptable audio format such as MP3 in the <enclosure tag> and this should resolve your issue.
For the images of a show or episode, podcast images need to have a fully squared (1:1) aspect ratio in the highest resolution available. We accept PNG or JPEG file formats for image assets.
Please refer to our delivery specification for further information.
