개요

HTML <audio> 요소는 문서에 소리 컨텐츠를 포함하기 위해 사용됩니다. 이것은 src 속성이나 <source> 요소를 통해 여러 오디오 소스를 포함할수 있으며, 브라우저는 그중에 가장 적합한 소스를 고를것입니다.

<audio> 요소를 지원하지 않는 브라우저를 위해 대체 컨텐츠를 추가할수도 있습니다.

You can use the Web Audio API to directly generate and manipulate audio streams from JavaScript code. 자세한 내용은 Web Audio API를 참조하세요

속성

이 요소는 전역 속성만을 포함합니다.

autoplay
Boolean 속성; if specified (even if the value is "false"!), the audio will automatically begin to play back as soon as it can do so without stopping to finish loading the data.
autobuffer 안씀 Gecko 2.0
Boolean 속성; if specified, the audio will automatically begin being downloaded, even if not set to automatically play. This continues until the media cache is full, or the entire audio file has been downloaded, whichever comes first. This should only be used when it is expected that the user will choose to play the audio; for example, if the user has navigated to a page using a "Play this audio" link. This attribute was removed in Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1) in favor of the preload attribute.
buffered
An attribute you can read to determine which time ranges of the media have been buffered. This attribute contains a TimeRanges object.
controls
If this attribute is present, the browser will offer controls to allow the user to control audio playback, including volume, seeking, and pause/resume playback.
loop
A Boolean attribute; if specified, we will, upon reaching the end of the audio, automatically seek back to the start.
mozCurrentSampleOffset
The offset, specified as the number of samples since the beginning of the audio stream, at which the audio is currently playing.
muted
A Boolean attribute which indicates whether the audio will be initially silenced. Its default value is false, meaning that the audio will be played.
played
A TimeRanges object indicating all the ranges of the audio that have been played.
preload
This enumerated attribute is intended to provide a hint to the browser about what the author thinks will lead to the best user experience. It may have one of the following values:
  • none: hints that either the author thinks that the user won't need to consult that audio or that the server wants to minimize its traffic; in others terms this hint indicates that the audio should not be cached;
  • metadata: hints that though the author thinks that the user won't need to consult that audio, fetching the metadata (e.g. length) is reasonable;
  • auto: hints that the user needs have priority; in others terms this hint indicated that, if needed, the whole audio could be downloaded, even if the user is not expected to use it;
  • the empty string: which is a synonym of the auto value.

If not set, its default value is browser-defined (i.e. each browser can choose its own default value), though the spec advises it to be set to metadata.

사용 참고:
  • The autoplay attribute has precedence over this one as if one wants to automatically play a audio, the browser will obviously need to download it. Setting both the autoplay and the preload attributes is allowed by the specification.
  • The browser is not forced by the specification to follow the value of this attribute; it is a mere hint.
src
포함될 오디오의 URL. This is subject to HTTP access controls. This is optional; you may instead use the <source> element within the audio block to specify the audio to embed.
volume
The playback volume of any audio portions, in the range 0.0 (silent) to 1.0 (loudest).

Time offsets are specified as float values indicating the number of seconds to offset.

Note: The time offset value definition has not yet been completed in the HTML5 specification and is subject to change.
