The DOM Audio seekable property is used for returning a TimeRanges object. The TimeRanges object is used for representing the ranges of the audio which are available for seeking by the user. The time range of audio which is available for seeking i.e. moving playback position is called a seekable range. It is often possible to seek anywhere in the audio even before it has been buffered if it’s a non-streaming audio. The Audio seekable property is a read-only property. The time ranges object properties are:
- length: It is used to get the number of seekable ranges in the audio.
- start(index): It is used to get the position of a seekable range.
- end(index): It is used to get the end position of a seekable range.
Syntax:
audioObject.seekable
