HTML Audio
🎯 한 줄 통찰 (One-line insight)
The HTML <audio> element plays sound natively in a page; multiple <source> children let the browser pick the first supported format, with controls, autoplay, and muted attributes governing playback. [S1]
🧠 핵심 개념 (Core concepts)
<audio>plays sound — it embeds an audio player directly in the page. [S1]controlsadds the UI — thecontrolsattribute adds audio controls such as play, pause, and volume. [S1]- Multiple
<source>for fallback — list several<source>elements with different formats; the browser uses the first recognized one. Text between the tags shows if none is supported. [S1] autoplaystarts on load, but Chromium browsers do not allow autoplay in most cases; muted autoplay is always allowed. [S1]- Three HTML-standard formats — MP3, WAV, and Ogg. [S1]
- Scriptable — like video, audio has DOM methods, properties, and events for JavaScript control. [S1]

📖 세부 내용 (Details)
The HTML <audio> element — used to play an audio file on a web page. To play an audio file, use the <audio> element. The controls attribute adds audio controls (play, pause, volume). The <source> elements link to different audio files; the browser uses the first recognized format. The text between <audio> and </audio> is displayed only in browsers that do not support the element: [S1]
<audio controls>
<source src="horse.ogg" type="audio/ogg">
<source src="horse.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
HTML <audio> autoplay — to start an audio file automatically, use the autoplay attribute. Note: Chromium browsers do not allow autoplay in most cases; however, muted autoplay is always allowed: [S1]
<audio controls autoplay>
<source src="horse.ogg" type="audio/ogg">
<source src="horse.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
Add muted after autoplay to let the file start playing automatically (but muted): [S1]
<audio controls autoplay muted>
<source src="horse.ogg" type="audio/ogg">
<source src="horse.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
HTML audio formats — three formats are supported: MP3, WAV, and Ogg. Their MIME (media) types: [S1]
| Format | Media Type |
|---|---|
| MP3 | audio/mpeg |
| OGG | audio/ogg |
| WAV | audio/wav |
Browser support varies by format (per the source): MP3 and WAV are supported across Edge/IE, Chrome, Firefox, Safari, and Opera; OGG is supported in Edge (from Edge 79), Chrome, Firefox, and Opera, but not Safari. [S1]
HTML audio — methods, properties, and events — HTML defines DOM methods, properties, and events for the <audio> element, allowing JavaScript to load, play, and pause audio, set duration and volume, and react to events. The source directs to the "HTML Audio/Video DOM Reference" for the full list. [S1]
HTML audio tags — [S1]
| Tag | Description |
|---|---|
<audio> |
Defines sound content |
<source> |
Defines multiple media resources for media elements, such as <video> and <audio> |
🛠️ 적용 사례 (Applied in summary)
The examples above are the canonical applied uses: a controlled player offering Ogg with an MP3 fallback, an autoplay variant, and a muted-autoplay variant that complies with modern browser autoplay policies. No external project/commit applications found in the source.
💻 코드 패턴 (Code patterns)
Standard audio player with fallback (HTML):
<audio controls>
<source src="horse.ogg" type="audio/ogg">
<source src="horse.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
Muted autoplay (HTML):
<audio controls autoplay muted>
<source src="horse.mp3" type="audio/mpeg">
</audio>
⚖️ 모순 및 업데이트 (Contradictions & updates)
No contradictions found in the source. As with video, the notable constraint is browser autoplay policy: autoplay alone is blocked by Chromium browsers in most cases, so muted is required for reliable autoplay. [S1]
