SoxLibraryForAndroid

Easy to use Sox library for android, with all the classic sound processing kungfu included.

First of all, this project is based on SoxLibInAndroid for the .aar file sources, and the java helper class with easy to use functions are based on android-ffmpeg-java

Installation

1. Download the soxcommandlibrary-release.aar file onto your computer
2. Then in your app module build.gradle file, add the path to the downloaded file like the example below

dependencies {
  implementation files('/Users/Bob/path/to/file/soxcommandlibrary-release.aar')
}

3. Sync the project

Example usage:

    import com.vtech.audio.helper.SoxCommandLib;

    // Simple combiner
    // sox file[0] file[1] ... file[n] <outFile>

    String soxCommand = "sox -m in1.mp3 in2.mp3 in3.mp3 out.mp3"
    int exitVal = SoxCommandLib.executeCommand(soxCommand);
 
    if(exitVal == 0){
      Log.v("SOX", "Sox finished successfully");
    }else{
      Log.v("SOX", "Sox failed");
    }
 

Example usage with helper methods:

    public void mixAllSoundsAndPlay(ArrayList<String> audioFilePaths, String audioOutPath) throws FileNotFoundException, IOException{

        ShellCallback mixDoneResponse = new ShellCallback() {

            @Override
            public void shellOut(String shellLine) {
                // TODO Auto-generated method stub
            }

            @Override
            public void processComplete(int exitValue) {
                // TODO Auto-generated method stub

                playCombinedSound(audioOutPath);

            }
        };

        Context context = getApplicationContext();

        SoxController mAuxController = new SoxController(context, mixDoneResponse);

        // when the processing is done, you will get a callback response in the ShellCallback above
        mAuxController.combineMix(audioFilePaths, audioOutPath); // so simple 😊
