- /**
- * Ignores source values for `duration` milliseconds, then emits the most recent
- * value from the source Observable, then repeats this process.
- *
- * <span class="informal">When it sees a source value, it ignores that plus
- * the next ones for `duration` milliseconds, and then it emits the most recent
- * value from the source.</span>
- *
- * 
- *
- * `auditTime` is similar to `throttleTime`, but emits the last value from the
- * silenced time window, instead of the first value. `auditTime` 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. After `duration` milliseconds (or
- * the time unit determined internally by the optional `scheduler`) has passed,
- * 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.
- * Optionally takes a {@link SchedulerLike} for managing timers.
- *
- * ## Example
- *
- * Emit clicks at a rate of at most one click per second
- *
- * ```ts
- * import { fromEvent, auditTime } from 'rxjs';
- *
- * const clicks = fromEvent(document, 'click');
- * const result = clicks.pipe(auditTime(1000));
- * result.subscribe(x => console.log(x));
- * ```
- *
- * @see {@link audit}
- * @see {@link debounceTime}
- * @see {@link delay}
- * @see {@link sampleTime}
- * @see {@link throttleTime}
- *
- * @param duration Time to wait before emitting the most recent source value,
- * measured in milliseconds or the time unit determined internally by the
- * optional `scheduler`.
- * @param scheduler The {@link SchedulerLike} to use for managing the timers
- * that handle the rate-limiting behavior.
- * @return A function that returns an Observable that performs rate-limiting of
- * emissions from the source Observable.
