m4b-tool 命令

常用示例

说明

m4b-tool is a PHP-based command-line wrapper around ffmpeg and mp4v2 that creates, splits, retags, and inspects M4B audiobook files. The merge subcommand concatenates a directory of audio files (MP3, M4A, WAV, FLAC, etc.) into a single AAC-encoded M4B, automatically inserting chapter markers based on the order of input files or an accompanying chapters.txt. The split subcommand reverses the process, exporting each chapter as a separate file in a chosen format. chapters allows inspecting or rewriting the chapter table, optionally aligning markers to detected silences with --adjust-by-silence for better playback experience. meta edits ID3/MP4 tags and can embed cover artwork. A persistent cache speeds up repeated runs across the same files; disable it with --no-cache when input changes are not being detected.
