# Rx-Gate

Rx operator that functions similar to a filter with time restrictions.  The gate only lets values through 

if they satisfy a threshold function for a certain amount of time. It can also be configured to let values

through after they stop satisfying the threshold function for a specified period of time.

A common use case for a gate is in audio data processing. The gate is usually configured to let audio data through

when the amplitude of the audio signal passes the threshold and stays there for a certain period of time. The audio

is also allowed to pass for a certain amount of time after is has dropped below the threshold amplitude in case the

amplitude picks up again to avoid unnecessary silences.

Example of usage (taken from a audioprocessing rx pipeline)

```

...

AudioReaderObservable.build(sampleRate, blockSize)

    .observeOn(Schedulers.io())

    .subscribeOn(Schedulers.io())

    .lift(

        new Gate<>(

            data -> {

                amplitude = AudioUtils.getAmplitude(data);

                return amplitude > threshold;

            },            

            750,

            250

        )

    ).subscribe(...);

...

```
