 * This hook can be used to apply css properties on an element based on the current audio level for the passed in track.
 * It doesn't return the audio level as it's optimised for performance. As audio level could be changing frequently we
 * want to minimise the number of components an audio level change causes to re render.
 * An e.g. use of this hook will be to apply box-shadow on parent tile based on audio level.
 * @param trackId is the audio track id for which audio level needs to be used
 * @param getStyle is a function which can take in current audio level and return the style to apply for the ref
 * @param ref is the ref of the element on which you want the css to apply
