I'm not familiar with game programing. Are sound effects small audio

There's also a trick called audio sprites where you put all sound
effects into a single file with some silence in between and then seek
to the appropriate offset.
I think if UA can get and set currentTime property accurately, it should be
able to recreate the pipeline
with the same accuracy. What are the main factors limiting the accuracy?
I don't know, but would guess that not all media frameworks can seek
to an exact audio sample but only to the beginning of a video frame or
an audio frame, in which case currentTime would be slightly off. One
could just lie about currentTime until playback continues, though.
Such limitation also affects seeking, not only memory-saving feature,
and the spec allows "quality-of-implementation issue", so I think this
is acceptable.
Additionally, a media in memory-saving state must be paused, I think
users won't care about the small error of resuming position.
