Understanding how Audiobook Studio organizes data is key to a smooth workflow.

🏗️ Hierarchy

• Library: The collection of all your projects.
• Project: Represents a single audiobook or collection. Contains metadata (Author, Series, Cover).
• Chapter: A logical division of a project. Contains the text and its generated audio.
• Segment: A single sentence or paragraph within a chapter. This is the smallest unit of generation.
• Character: A persona assigned to segments. Chapters are narrated by a "Narrator" by default, but you can assign specific "Characters" to dialogue.

🎙️ AI Voice Lab

• Voice Profile: A cloned voice based on short audio samples.
• Speaker: A higher-level grouping for Voice Profiles, allowing multiple "variants" (e.g., "Main - Calm", "Main - Shouting") under one identity.
• Sample: A 6–10 second .wav file used to train a Voice Profile.

🔄 Generation Workflow

1. Analysis: The system scans your text for long sentences (over 500 characters) and automatically splits them to ensure high-quality TTS.
2. Queuing: When you click "Generate", segments are added to a background queue.
3. Synthesis: The Coqui XTTS engine processes segments one by one.
4. Baking: After all segments in a chapter are generated, they are "stitched" together into a single master audio file for that chapter.
5. Assembly: Finally, all chapter audio files are bundled into a standard .m4b audiobook format with chapters and metadata.
