ReactiveAudioRecord

A reactive (Rx) implementation of the AudioRecord API for recording raw (pcm) audio-data. Also includes helper methods for the creation of Wave audio files.

How to use it?

Create an instance of RecorderOnSubscribe giving it the path to the file
final String filePath = Environment.getExternalStorageDirectory() + "/sample.wav"; //dummy file  RecorderOnSubscribe recorder = new RecorderOnSubscribe.Builder(filePath)

 .sampleRate(22000)

 //by default 44100

 .stereo()

 //by default mono

 .audioSourceCamcorder()  //by default MIC

 .build();
Use the recorder OnSubscribe to create an observable
Observable.create(recorder)

  .subscribe( shorts -> {

...

recorder.writeShortsToFile(shorts);
 //a helper method that writes the buffers to (wave) file

  
}
);

After setting up the Observer, manipulate the recording-process by using these methods

Name Description
start() Starts the recorder and moves it to Recording state
stop() Stops the recorder and moves it to Stopped state
pause() Pauses the recorder and moves it to Paused state
resume() Resumes the recorder if it's in Paused state
isRecording() Returns true if the recorder is in Recording state
isRecordingStopped() Checks whether the recorder is in Stopped state or not

Helper methods for wave file write operations

Name Description
writeShortsToFile(shorts) Writes the short buffers to wave file
completeRecording() Writes the Wave header info to the file (Call it after stop() method)

And that's it! Check out the sample code for a working example!

A fast dependency injector for Android and Java.

This project represents Google's fork of Square's Dagger. Google's Dagger fork is intended to vary from Square's project only where features are needed to deviate from Square's feature-set. Google's Dagger should be a drop-in compatible alternative to Square's Dagger, and many features in this fork will, if successful, be merged into the upstream project.

Efforts are made to also keep Google's fork as close in structure to Square's as possible, to facilitate merging and compatibility. Google/dagger will release shortly after Square's releases.

Why use Holdr?

  • Because you hate typing findViewById() all the time.
  • Because Butterknife requires non-zero boilerplate and doesn't work well in library projects.
  • Because view holders are cool, but a pain to write.
