Inputs
Text chapters are plain text; voice samples are common audio formats. See File Formats.
Internal vs output formats
Studio renders to WAV internally, then exports MP3 or M4B. Working in WAV keeps quality high until the final export.
Quality tips
- Pick a sensible export bitrate for spoken word.
- Let Studio normalize levels for consistent loudness.
- Keep per-segment text within the engine's chunk limit.
