A book, not just a file

On your computer
Your audio stays local.
Import, preview and export run on your Windows PC. The current application has no audio upload, cloud conversion or automatic diagnostic upload feature.
Project files and work audio are stored locally. You choose the export folder; large books need free space for temporary PCM audio.

Built for Windows.
System & storage
- Platform
- Intended for Windows 10 / 11, x64. No native macOS, Linux or ARM build.
- Installation
- Runtime and audio engine included. No separate Python or FFmpeg installation. Windows administrator approval is needed for setup, not everyday use.
- Free space
- Allow roughly 1 GiB for setup, plus your files and work space. Prepared PCM uses about 606 MiB per audio hour in stereo or 303 MiB in mono.
Formats & boundaries
- Input
- Up to 500 MP3, FLAC, M4A or WAV files, each with one mono/stereo audio stream. Local drives only.
- Output
- M4B with AAC-LC, 44.1 kHz, 64 / 96 / 128 kbps. Conversion is lossy, not lossless remuxing.
- Not included
- DRM removal, website downloads, text-to-speech, automatic speech segmentation or editing an existing chaptered M4B.
Final Windows release acceptance is still in progress. Low-end hardware minimums and compatibility with every audiobook player have not been certified.
Can I buy or download it now?
Not yet. The software is in pre-release testing as version 0.9.0 RC1. There is no checkout, pre-order or public installer download. The intended price is $9.99 USD as a one-time purchase; final terms are not yet available.
Can I mix MP3, FLAC, M4A and WAV?
Yes. Supported mono/stereo source files are converted to a common output format. Each source file becomes one chapter. Corrupt files, DRM-protected audio, multiple audio streams and sources that already contain chapters are not supported.
Does my audio leave my computer?
No upload is part of the current conversion workflow. Audio, cover processing and project work stay local. This website is separate from the desktop application; its host processes normal web requests. See the Privacy Policy.
Will the M4B work in my player?
Player support varies. Exported files include chapter titles, artwork and book metadata, but their display and chapter navigation depend on your player. Limited VLC checks and user listening feedback are not certification for every player or long book. Apple Books and mobile transfers are not certified. Narrator uses the composer tag; series uses grouping.
Is the conversion lossless?
No. Audio is encoded to AAC-LC at the selected bitrate. A higher bitrate cannot restore information missing from the original. There is no lossless passthrough, loudness normalization or silence removal.
Can I cancel and continue later?
You can cancel an export and reuse completed, compatible PCM preparation work when retrying in the same output folder. An unfinished chapter or the final encode starts again, not at its previous position. Saved projects reference the original files, so keep those files available.
What does the planned one-time price include?
The intended model is a one-time software purchase, not a recurring subscription. Device allowances, update entitlement, delivery and any future trial or activation model are not finalized. They will be stated before any sale. There is no account, trial restriction or activation service in the current candidate.
