Import a book, edit chapters, pick a voice, and export to **WAV / MP3 / M4B** with chapter marks.\n\n## Features\n- **Document import** — TXT, PDF, EPUB with automatic chapter detection\n- **Chapter editor** — reorder, search/filter, per-chapter voice, add/delete, live duration estimates\n- **Voices** — multiple offline Kokoro models (English + 100+ multilingual voices); optional GPU engines (XTTS v2, Chatterbox) with voice cloning\n- **Pacing** — global pause scale plus per-type pauses (comma, sentence, ellipsis, paragraph) and inline `[pause 500]` tags\n- **Audio** — loudness normalization (Peak / RMS / true **LUFS** BS.1770), silence trimming, export presets (ACX / Podcast / Plain), optional background music + intro/outro\n- **Export** — WAV, MP3 (with ID3 chapter marks), M4B audiobook with cover art\n- **Player** — built-in preview player, mini player, pronunciation dictionary, dark/light/midnight themes\n\n## Requirements\n- Windows 10/11, x64\n- .NET 8 SDK (to build) — or use the self-contained build (no install needed)\n- **ffmpeg** on PATH (for M4B, MP3 chapter marks, background-music mixing)\n- **GPU engines only:** an Nvidia GPU + CUDA. Python 3.10+ is auto-installed if absent.\n\nThe Kokoro TTS models (~80 MB+) download automatically on first run.\n\n## Build \u0026 run\n```powershell\ngit clone https://github.com/musika08/Audiobooks.git\ncd Audiobooks\ndotnet build TTSApp/TTSApp.csproj -c Debug\n# run the produced TTSApp.exe under TTSApp/bin/Debug/net8.0-windows10.0.17763.0/\n```\n\n## Package a portable build / installer\n```powershell\npowershell -ExecutionPolicy Bypass -File build\\publish.ps1   # -\u003e .\\publish\niscc build\\installer.iss                                     # -\u003e installer .exe (needs Inno Setup)\n```\n\n## Engines\n| Engine | Device | Voices | Cloning |\n|--------|--------|--------|---------|\n| Kokoro English v0.19 | CPU | 11 | no |\n| Kokoro Multi-Lang v1.0 | CPU | 53 | no |\n| Kokoro Multi-Lang v1.1 | CPU | 103 (mostly Mandarin) | no |\n| XTTS v2 | GPU | built-in studio voices | yes |\n| Chatterbox | GPU | default | yes |\n| Fish / OpenAudio | GPU | experimental | — |\n\nGPU engines run as a local Python sidecar (`TTSApp/python/`), started automatically by the app. See [TTSApp/python/README.md](TTSApp/python/README.md).\n\n## Project layout\n- `TTSApp/` — WPF app source\n- `TTSApp/python/` — GPU TTS sidecar (FastAPI server + engines)\n- `build/` — publish script + Inno Setup installer\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmusika08%2Faudiobooks","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmusika08%2Faudiobooks","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmusika08%2Faudiobooks/lists"}
