Everything in the box
Why MP3? Because it plays everywhere.
MP3 is the universal audio format. No special app. No account. No internet connection. Just press play.
- Car stereo. USB stick, Bluetooth, AUX cable. Your ebook plays on any car system built in the last 20 years.
- Any phone or tablet. iOS, Android, Windows, Linux. MP3 works on every device without installing anything extra.
- Offline listening. No Wi-Fi? No problem. MP3 files live on your device. Listen on a plane, trail, or subway.
- Share with anyone. Send the file to a friend, load it onto a grandparent's device. No logins needed.
- Old-school players. MP3 players, iPods, fitness watches. If it plays audio, it plays MP3.
- No screen required. Compare that to reading an EPUB on a screen. MP3 frees your eyes and hands.
Your ebook library just became a podcast library. Except you pick the voices.

What happens to your book (under the hood)
An EPUB file is a structured archive — HTML chapters, a table of contents, metadata. Our AI uses that structure to produce a better MP3 than any flat-text converter could.
- 1Chapter extraction. AI reads the EPUB manifest and splits the book into its original chapters. No guessing, no arbitrary cuts.
- 2Character detection. Dialogue tags and character names are identified. The AI builds a cast list so you can assign voices.
- 3Voice assignment. You pick voices for the narrator and each character. Or let AI suggest voices based on character traits.
- 4Narration generation. Each chapter is narrated with the correct voices. Dialogue switches seamlessly between characters.
- 5MP3 export. Download chapter-by-chapter or as one complete file. High-quality MP3, ready for any device.
Because EPUB preserves book structure, the result is cleaner than converting from PDF (broken paragraphs) or plain text (no chapters). Your book already did the hard work — we just read it aloud.

Questions?
How do I convert EPUB to MP3?
Upload your EPUB file at notevibes.com/audiobook-narration. AI extracts chapters and characters, you assign voices, then click generate. Download the result as MP3 files.
Is EPUB to MP3 conversion free?
You can try the converter free with up to 1,000 characters. Full book conversion is available on paid plans starting at $19/month with 100,000 characters included.
What MP3 quality does the converter produce?
Audio is generated at high-quality MP3 (48kHz). Voices use neural TTS engines from Google, Amazon, Microsoft, and OpenAI — the same tech behind modern voice assistants.
How long does conversion take?
A typical novel (60,000-80,000 words) takes 10-20 minutes. Short stories and single chapters are ready in under a minute. You can preview chapters before generating the full book.
Can the AI detect characters in my book?
Yes. Notevibes scans your EPUB for dialogue tags and character names. It builds a cast list and lets you assign a unique voice to each character. Review and adjust before generating.
Will the MP3 play on my car stereo?
Yes. MP3 is the most widely supported audio format. It works on car stereos, phones, tablets, computers, MP3 players, smart speakers, and basically anything with a speaker.
Can I convert DRM-protected EPUBs?
No. The converter works with DRM-free EPUB files only. If your ebook has DRM, check whether the publisher offers a DRM-free download.
What languages are supported?
Notevibes supports 57 languages including English, Spanish, French, German, Portuguese, Japanese, Chinese, Korean, Arabic, Hindi, Russian, and more. Each language has multiple voice options.
Can I sell the MP3 audiobook I create?
Yes. All paid plans include full commercial usage rights. Distribute, sell, or publish the audiobooks you create on platforms like Audible, Google Play, or your own site.
What if I have a PDF instead of an EPUB?
Notevibes also supports PDF to audio conversion. For best results, EPUB is preferred because it preserves chapter structure and clean text. But PDF works too.
Your ebook, now an MP3
Upload your EPUB. Pick the voices. Download MP3 files that play anywhere — car, phone, speaker, watch. Your book finally fits in your pocket and your schedule.
