* Ignores source values for `duration` milliseconds, then emits the most recent

|
* <span class="informal">When it sees a source values, it ignores that plus
|
||

|

|
|
* `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));

* by the optional `scheduler`.
