tone is a cross platform audio tagger and metadata editor to dump and modify metadata for a wide variety of formats, including mp3, m4b, flac and more. It has no dependencies and can be downloaded as single binary for Windows, macOS, Linux and other common platforms.

The code is written in pure C# and utilizes the awesome atldotnet library to provide full support for a wide variety of audio and metadata formats.

Features:

The main purpose of tone is to tag m4b audio books for myself. It is planned as a successor to [m4b-tool].
