noiz://

A browser-based audio player with real-time spectrum visualization, VU metering, and comprehensive playlist management. Loaded entirely from a single index.html file — no build step, no server, no dependencies.

Features

• Real-time FFT spectrum analyzer — smooth animated frequency bars with configurable window function (Hanning / Blackman-Harris) and adjustable peak decay
• VU meter — per-channel level display with peak indicators
• Metadata parsing — reads ID3v1 and ID3v2 tags (title, artist, album, genre, year), plus inline codec info for MP3 and FLAC
• Playlist — sortable by title, artist, filename, length, or genre; supports shuffle and repeat (off / all / one)
• Crossfade — optional gapless transition between tracks (1s–5s)
• Drag & drop — drop folders or individual files; handles nested directories via the File System Access API (with webkitdirectory fallback)
• Keyboard shortcuts — Space (play/pause), ← (previous), → (next)

Usage

Open index.html in any modern browser. Click +Folder, +Files, or drag audio files onto the window.
