* 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 values, 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 IScheduler} for managing timers. |
|
* |
|
* @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.auditTime(1000); |
|
* result.subscribe(x => console.log(x)); |

|
* @param {number} 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} [scheduler=async] The {@link IScheduler} to use for |
|
* managing the timers that handle the rate-limiting behavior. |
|
* @return {Observable<T>} An Observable that performs rate-limiting of |
|
* emissions from the source Observable. |
