`\u003caudio-visualiser\u003e`\n\nFFT Audio Analyser visuals ready for retina displays.\n\nNote: Uses ResizeObserver. Polyfill it on your end.\n\n## API\n\n### Inputs\n\n| Method | Description | Related media event |\n| --- | --- | --- |\n| `set analyser` | Set analyser to read data from. |  |\n| `start()` | Start the visuals drawing loop. | [`play`](https://developer.mozilla.org/en-US/docs/Web/Events/play) |\n| `stop()` | Stop the visuals drawing loop. | [`pause`](https://developer.mozilla.org/en-US/docs/Web/Events/pause) / [`ended`](https://developer.mozilla.org/en-US/docs/Web/Events/ended) |\n\n| Attribute | Description |\n| --- | --- |\n| `color` | Sets the color of the visual. |\n\n## Usage\n\nInstall audio-visualiser via npm or import it in your ES module supported browser with `import 'https://cdn.skypack.dev/audio-visualiser';`\n\nCreate an AnalyserNode and connect it to \u003caudio-visualier\u003e by calling the setter `analyser` on the instance of the custom element. `document.querySelector('audio-visualiser').analyser = yourAnalyserNode;`. For a little live demo of this you can check out https://enjikaka.github.io/audio-visualiser/. Open dev tools or view-source to see how the \u003caudio\u003e tag is set up to the analyser via createMediaElementSource.\n\n```html\n\u003caudio id=\"audio\" src=\"worth-fighting-for.mp3\" controls\u003e\u003c/audio\u003e\n\u003caudio-visualiser id=\"visuals\" color=\"rebeccapurple\"\u003e\u003c/audio-visualiser\u003e\n```\n\n```js\nimport 'https://cdn.skypack.dev/audio-visualiser';\n\nconst audio = document.getElementById('audio');\nconst visuals = document.getElementById('visuals');\n\naudio.currentTime = 41;\n\nconst audioContext = new AudioContext();\n\nconst source = audioContext.createMediaElementSource(audio);\nconst analyser = audioContext.createAnalyser();\n\nanalyser.fftSize = 1024;\n\nsource.connect(analyser);\nanalyser.connect(audioContext.destination);\n\nvisuals.analyser = analyser;\n\naudio.addEventListener('play', () =\u003e {\n  audioContext.resume();\n  console.log('playing');\n  visuals.start();\n});\n\naudio.addEventListener('pause', () =\u003e {\n  console.log('paused');\n  visuals.stop();\n});\n```","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fenjikaka%2Faudio-visualiser","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fenjikaka%2Faudio-visualiser","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fenjikaka%2Faudio-visualiser/lists"}
