| startInSource | number | true | - | - | The start time of the audio clip in the source file, in seconds. Usually 0, only differs from 0 when the audio node has been trimmed from the front of the source audio. The sum of startInSource and duration must be less than or equal to sourceDuration. |
| sourceDuration | number | true | - | - | The total duration of the source audio file, in seconds. This field should match the actual length of the source audio. |
| isFrontTrimmed | boolean | false | - | - | Indicates whether the audio has been trimmed from the front of the source audio. Should be set to true when startInSource is not 0. |
| volume | number | true | - | 0 - 1 | The volume level of the audio element. 1 represents full volume, and 0 represents muted. |
Note: The externalUrl must be accessible. The
sourceDurationfield must match the actual duration of the source audio file. The sum ofstartInSourceanddurationmust be less than or equal tosourceDuration, which allows you to use only a portion of the audio clip in the timeline - usuallystartInSourceis 0, and only differs from 0 when the audio node has been trimmed from the front of the source audio. WhenstartInSourceis not 0, you should setisFrontTrimmedto true. Thevolumefield enables volume adjustments for precise sound control.
