terminate an audio before it finishes

[tunggiya]

I wonder if there's already a way to terminate an audio before it finishes? If this is not currently implemented, I think it'd be nice to add this functionality at least to the lock-screen widget, in case the button was tapped accidentally. (e.g. stop the audio when the user double-taps a button, instead of trigger the sound twice again overlapping previous sounds)
It'd be nice to more control over how audio files are played in-app as well, for example, choose between whether to stop a previous sound when a second button is pressed, instead of always have multiple sounds overlapping each other, because in the actual app I might just be checking out a new library, therefore care less about mixing effects of different sounds.

Thank you :)
