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 an episode's audio be changed after publishing ?
Yes, episode audio can be replaced after intial upload. This process allows a new audio file to be uploaded which will replace the existing audio.
It is important to note that there is no distinction on usage analytics between the different versions, so if audio is replaced there is no way to see in analytics how many listeners listened to the previous version. If this is required, we recommend creating a new episode and deleting the first one.
How do I upload audio ?
To get started you need to be on an existing podcast show page and logged in with your iono.fm admin user profile.
On the channel admin panel use the "Publish episode" button to create a new episode in that show.
This button opens the "Create episode" form where details of the episode can be specified, including it's audio file.
The "Upload audio file" button opens a dialog where an audio file can be provided in a various ways:
- Upload a file directly from your computer by using the "Browse" button. (The audio file can also be dragged & dropped from your computer.)
- Specify a publicly accessible HTTP URL on the web where the file can be downloaded.
- Specify a FTP server URL with username and password where the file can be downloaded.
What kind of audio files can I upload ?
We accept various file formats as input, but recommend AAC or MP3 for most users.
Also supported are FLAC, WAV, Ogg and MP2.
What is the recommended upload format and quality ?
Our platform does not serve the uploaded file directly to listeners.
We store a high-quality version of the original file in AAC format and create several distribution files in multiple quality profiles (see Audio quality levels & file formats).
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 files compressed with AAC at 128 - 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 bitrates of 192kbps to 256kbps. Our platform also accepts variable bitrate encoded MP3 and AAC files.
- We recommend against using WAV as an upload format due to it's massive size.
- We accept FLAC files, but do not store the audio archive in with lossless compression.
