Get recommended episode length by topic, audience and ad load, plus accurate MP3 / AAC file size estimates for any bitrate.
| Duration | MP3 (kbps) | File size |
|---|
Recommended length blends two signals: (1) typical format duration from Edison/Spotify research, and (2) audience listening context (commute averages 27 min, workouts 38 min, deep listens 75+ min).
File size = bitrate × duration. 128 kbps × 60 min = 128/8 × 3600 ≈ 57.6 MB. Most directories cap at 500 MB per file.
