Warning: Media URL contains more than 5 redirects
Blubrry PowerPress checks that your media URLs do not exceed 5 redirects for maximum compatibility with podcast apps such as Apple Podcasts.
A URL redirect is an instruction given by the server to the client to connect to another URL. Some redirects are for calculating statistics while others are used to route the request to the appropriate server where the actual file is hosted.
Most HTTP compliant applications (podcast apps and web browsers) will handle between 12 to 20 redirects before failing. Some applications will fail after 5 redirects. It is recommended that your Media URL not exceed 5 redirects in order to reach the widest possible audience.
Warning: Channel mode ‘mono’
Blubrry PowerPress checks that your MP3 media is either in ‘stereo’ or ‘joint stereo’ for maximum player compatibility.
Web-based media players and some portable media players require either stereo or joint stereo for proper playback. Playback typically fails instantly in players that do not support mono. To reach the widest audience possible, we recommend using joint stereo when creating your MP3 media. Joint stereo and mono result in the same file size, so switching from mono to joint stereo should not be an issue if file size is a concern.
Values other than these noted may result in media files that are not compatible with some media players and web flash players.
Warning: Sample rate is not 22Khz or 44Khz
Blubrry PowerPress checks that your mp3 media is using either 22Khz or 44Khz sample rate for maximum player compatibility.
Web-based media players require the sample rate be either 22Khz or 44Khz in order to playback the media correctly. When your mp3 is not set to the correct sample rate, playback may become accelerated, giving the effect of sounding like a member of The Chipmunks. To avoid this Chipmunk effect, we recommend using either 22Khz or 44Khz in your mp3 media.
Values other than these noted may result in media files that are not compatible with some web players.
