/** |
|
* Ignores source values for a duration determined by another Observable, then |
|
* emits the most recent value from the source Observable, then repeats this |
|
* process. |
|
* |
|
* <span class="informal">It's like {@link auditTime}, but the silencing |
|
* duration is determined by a second Observable.</span> |

|
* `audit` is similar to `throttle`, but emits the last value from the silenced |
|
* time window, instead of the first value. `audit` emits the most recent value |
|
* from the source Observable on the output Observable as soon as its internal |
|
* timer becomes disabled, and ignores source values while the timer is enabled. |
|
* Initially, the timer is disabled. As soon as the first source value arrives, |
|
* the timer is enabled by calling the `durationSelector` function with the |
|
* source value, which returns the "duration" Observable. When the duration |
|
* Observable emits a value or completes, the timer is disabled, then the most |
|
* recent source value is emitted on the output Observable, and this process |
|
* repeats for the next source value. |
|
* |
|
* @example <caption>Emit clicks at a rate of at most one click per second</caption> |
|
* var clicks = Rx.Observable.fromEvent(document, 'click'); |
|
* var result = clicks.audit(ev => Rx.Observable.interval(1000)); |
|
* result.subscribe(x => console.log(x)); |

|

|

|
* @param {function(value: T): SubscribableOrPromise} durationSelector A function |
|
* that receives a value from the source Observable, for computing the silencing |
|
* duration, returned as an Observable or a Promise. |
|
* @return {Observable<T>} An Observable that performs rate-limiting of |
|
* emissions from the source Observable. |
