midway point through a 10-second audio buffer is still 5.
- `duration` {{optional_inline}}
- : The duration of the sound to be played, specified in seconds. If this parameter
isn't specified, the sound plays until it reaches its natural conclusion or is stopped
using the {{domxref("AudioScheduledSourceNode.stop", "stop()")}} method. Using this
parameter is functionally identical to calling `start(when, offset)` and
then calling `stop(when+duration)`.
- : The duration of the audio data to be played, specified as seconds of total buffer content.
If this parameter isn't specified, the sound plays until it reaches its natural conclusion or
is stopped using the {{domxref("AudioScheduledSourceNode.stop", "stop()")}} method. The
value is independent of the {{domxref("AudioBufferSourceNode.playbackRate")}}, so e.g., a
`duration` of 2 seconds with a `playbackRate` of `2` will play 2 seconds of the source,
producing a 1 second audio output.
