## What it is
A browser-based audio spectrum visualizer built with the HTML5 Audio API. Users can drag and drop or select an audio file to play and see its frequency spectrum rendered in real time.

## Use cases
- visualize audio spectrum in the browser
- build a music player with a frequency visualizer
- learn how to use the HTML5 Web Audio API
- create an audio spectrum analyzer demo
- render real-time audio waveform graphics on canvas

## When to choose
- you need a lightweight, dependency-free browser audio visualizer
- you want a simple reference implementation of the HTML5 Audio API
- you want a demo users can drag and drop audio files into

## When to avoid
- you need server-side audio analysis
- you need a production music player with playlists and controls
- you need visualizations for non-audio data

## Facets
- artifact type: application
- maturity: maintenance
- function: audio-processing, data-visualization
- domain: web-development, media
- platform: browser, cross-platform
- tags: audio-visualizer, html5-audio-api, spectrum-analyzer, web-audio, canvas, audio, web-server
