Batch audiobook processing and metadata management
for personal libraries
Merge multiple audio files into a single M4B audiobook. Process your entire library, not one file at a time.
Title, author, narrator, series, cover art. Edit everything before export. Compatible with Audiobookshelf, Plex, and Apple Books.
Configure AAC-LC encoding — bitrate, sample rate, and channel layout. Preview before committing to a full encode.
Built on ffmpeg-next with a native Rust audio pipeline. No shell wrappers, no overhead — direct codec access for maximum throughput.
A native desktop app, not an Electron wrapper. Small footprint, fast startup, full OS integration.
