How large can podcast audio files be?

Getting a message your audio file won't upload due to file size?

We typically don't recommend files any larger than 200MB.

"Downloading large files takes up more bandwidth and can cause data transfer limits to be hit quickly. You don’t want to be a hog and take up all the space on the listeners devices, or cause them to wait several hours while your episode finishes downloading." – Derrick at Signal Leaf

We've also seen podcast subscribers who will unsubscribe from a show if the files are too big. (Remember, many podcast listeners download your files to their phone).

Our recommendation: audio files (MP3 is preferred) should be encoded at 44100 Hz and around 128 kb/s quality.
