Required · Step 6

Tag the file

Title, artwork, episode number and chapters inside the MP3 itself.

What this step is

Write the episode’s information into the audio file: title, show name, artwork, episode number, and optionally chapter markers. These are ID3 tags. Apps and players read them when the feed is not available, and a tagged file travels well on its own.

What you need

• Final MP3 (or similar), exported at a sensible bitrate for speech.
• Square artwork, at least 1400×1400 pixels, JPEG or PNG. Make this once for the show and reuse it.

Tools

Most editors write tags on export. Standalone: Kid3, MP3Tag, or a one-line script with ffmpeg.
