How do I publish a new episode ?

Visit the page of the channel you wish to publish the episode to and look for the 'Publish Episode' button.

Note that that you will only see this button if you are logged in with a user account that has publishing rights to the channel in question! (see this article)

Clicking the 'Publish Episode' episode button will present an interface where the an audio file can be provided in addition to allowing you setup metadata for your episode.


Can i replace an episode's audio after publishing ?

No, currently our platform does not allow replacing an existing episode's audio content with different audio data after publishing. 

All other episode metadata can be modified after publishing, but our platform views the underlying audio waveform of each episode as unique. This is important to ensure that the permalink for an episode always returns the same audio for end users. 

Additionally, our analytics track and report end-user access on a per-episode basis. Replacing the audio of an episode after it has been published makes it impossible to gauge how many listeners received the "old" audio and how many received the "new" audio.

Sometimes the publishing work-flow does require a change after the fact, for example when the audio contains an error that is only discovered after publishing. This currently requires archiving the faulty episode and then publishing a new one. 

(A future update may improve this work-flow by allowing publishers to make new episode appear to "replace" a previous one, retaining the unique audio and it's analytics but presenting all future listeners with the new version)


How do I upload audio ?

Our interface allows you to provide your audio file in various ways:
  • upload a file directly (with drag-and-drop if your browser supports it) 
  • specify a publicly accessible HTTP URL on the web where we can download the file directly 
  • provide a FTP server URL with username and password


    What kind of files can I upload ?


    We accept various file formats as input: 

    WAV, FLAC, MP3, MP2, Ogg Vorbis, AAC, Windows Media

    Note that these file types are identified only by their extension and must match the audio codec contained in the file!

    (.wav, .flac, .mp3, .mp2, .ogg, .oga, .mp4, .m4a, .wma respectively) 

         
    What is the recommended upload format and quality ?

    Our platform published all episodes in multiple quality levels (see this article).

    Ideally use a high-quality input file but strike a balance between quality and file-size by compressing it first using a (good) compression codec.

    For podcast content (voice with mixed in sounds) we recommend uploading 44.1kHz or 48kHz files compressed with AAC at 160kbps bitrate. At this compression level the quality is nearly transparent to uncompressed originals, even for music content. 
    For uploading in MP3 format we recommend using 192kbps compression.

    We strongly recommend against using WAV as an upload format due to it's massive size.


    What are archived episodes ?

    Archived episodes are only visible to content administrators and cannot be viewed or played by normal users. These episodes will never show up in a channel list view, either on the website, an RSS feed or an embedded player.

    Content administrators can use this to upload content and only publish it later or to reduce clutter for visitor by hiding older episodes.

    While episodes are in an archived state, administrators can still manage the them in normal ways, including changing it's metadata or deleting it. Existing live episodes can be archived using the "Archive" button on the episode's edit view.

    New episodes can be created directly to an archived state, preventing them from ever becoming visible to end-users. This allows uploading files for later publishing.

    To make archived episodes available to end users again, use the "Publish" button on the episode's edit view. Publishing takes a few moments to complete as new output files are created from the episode's archived original.
