Audiobook distribution
Audible, Spotify, Storytel, libraries — one upload.
Audiobook distribution shouldn't require six separate uploads to six platforms with six different metadata schemas. Chiify handles ACX, Apple, Spotify, Storytel, Kobo Audio, Hoopla, OverDrive, and library audiobook ingestion from a single drop of your audio files.
The audiobook market grew faster than every other publishing format for the last five years. Per-hour pricing is high. Library checkouts are explosive. But the platforms each have different file specs, different metadata fields, different submission portals, and Audible has ACX rules that change quietly.
Chiify handles all of that. You drop chapter files. We deliver to every audio platform you select, with the right file format and metadata each one demands.

File specs we accept (and validate)
For best results: WAV master files
- 44.1 kHz, 16-bit, mono or stereo
- One file per chapter, named numerically
- Opening credits, closing credits, and retail sample as separate files where ACX requires them
Also accepted: MP3
- 192 kbps CBR or higher
- Same chapter-per-file naming convention
Quality checks we run automatically
- Peak level — no clipping (peaks above -3 dBFS get flagged)
- RMS levels — chapters mastered close to ACX's -20 RMS guideline
- Room tone — silence at start and end of each chapter
- Length consistency — reasonable chapter lengths
ACX and Audible — what to expect
Audible is the largest audiobook retailer and worth the extra effort. Their ingestion (through ACX) is the strictest in the industry. We pre-validate your files against ACX's requirements so the actual submission goes cleanly.
ACX wants WAV files, RMS levels in a narrow window, peak -3 dBFS max, room tone at chapter boundaries, and one file per chapter. We auto-generate opening/closing credits from your metadata if you don't have them.
ACX reviews can take 10–15 business days. Going wide gets you onto Apple, Spotify, Storytel, and libraries — typically live within 2 weeks total.
Frequently asked
What audio file format do you need?
We accept WAV (44.1 kHz, 16-bit) or MP3 (192 kbps or higher). One file per chapter, named in sequence.
Does Audible take Chiify audiobooks?
Yes — through ACX. We handle submission, metadata, and compliance checks. If your file doesn't meet ACX specs, we tell you exactly what to fix.
Is Audible exclusive when I distribute through Chiify?
Up to you. We can submit exclusive or wide-distribution. Most Chiify authors go wide for Spotify, Storytel, and library reach.
What about library audiobook platforms?
Through our library aggregators we reach OverDrive, Hoopla, cloudLibrary, Bibliotheca, and Libby.
Can you produce the audiobook from my text?
Production (recording, narration, mastering) is not included — that's a separate craft. We can refer you to professional narrators or AI-narration services.
Does the ebook and audiobook need separate ISBNs?
Yes — ISO standard. We allocate separate ISBNs for each format automatically (both free on every plan).
