/**
 * 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.png)
 *
 * `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
 *
 * Emit clicks at a rate of at most one click per second
 * ```ts
 * import { fromEvent, interval } from 'rxjs';
 * import { audit } from 'rxjs/operators'
 *
 * const clicks = fromEvent(document, 'click');
 * const result = clicks.pipe(audit(ev => 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.
