From podcast to audiobook
Many podcasters go on to narrate a book. The skills overlap, but the standards are stricter, which is why a dedicated audiobook editing service exists.
Stricter technical rules
Audiobook retailers require specific loudness, peak and noise floor values for every chapter file. A file that sounds fine can still be rejected on measurements.
Consistency across hours
A book is recorded over many sessions, so tone and level must match from chapter to chapter. Pacing and room tone are standardized throughout.
Accuracy
The narration is checked against the manuscript for misreads and missing words. That proofing step rarely exists in podcast work.
