DFPlayer Organizer is a web-based utility that helps you prepare and structure audio files (WAV or MP3) for use on DFPlayer or any SD-card-based audio player. Key features:
- File Selection & Normalization
• Drag-and-drop or multi-select your WAV/MP3 files.
• Apply a gain-based normalization to bring all tracks to a consistent loudness. - Track Arrangement
• A “root” list for standalone tracks, plus as many nested folders as you need.
• Drag & drop tracks between the root and any folder.
• Automatic renumbering and duplicate highlighting—each track gets a zero-padded prefix (001, 002, …). - MP3 Encoding & Size Estimates
• Optionally re-encode to MP3 at 64–320 kbps.
• Live per-track and total-size estimates update whenever you change bitrate or move tracks. - Export & Flash Write
• Export your organized files (with new filenames) as a ZIP archive, complete with astructure.jsonmanifest.
• Or—using the browser’s File System Access API—write directly to an SD/flash directory you choose, includingstructure.json. - Built-in Player & Progress Feedback
• Preview each track in-browser with play/stop controls.
• A unified overlay shows progress during normalization, encoding, ZIP generation, and SD writing. - Zero-Config & Client-Side
• No server needed—everything runs 100% in your browser.
• Works offline once loaded, and leaves your original files untouched.
DFPlayer Organizer streamlines the process of normalizing, renaming, encoding, and exporting audio ready to drop onto an SD card for embedded audio players or DFPlayer Mini modules.
