mp3mark

Intro

mp3mark is a web-based site that lets you mark up and annotate audio and music. The available site text notes it works best on desktop and that files are processed locally. The interface provides a way to open projects in an editor and links to import documentation for guidance.

Key Features

• Web editor for annotating and inspecting audio files.
• Importing files and opening projects in the editor.
• Project metadata fields such as Project Name, BPM, and Time Signature (example shown: 4/4).
• Import documentation is available from the site to explain workflows.
• Files are processed locally in the browser (as stated on the site), which limits server-side handling of uploaded audio.

Who this is for

mp3mark is aimed at people who need to annotate or mark up audio or music files and prefer a desktop web workflow. Users who require per-project metadata (name, tempo, time signature) will find the necessary fields during setup. The site content does not include pricing, account, or full privacy-policy details in the captured text, and it emphasizes desktop use, which suggests limited mobile optimization. For questions about supported formats, collaboration, or account features, consult the import documentation or the site directly, since those items are not present in the provided content.
