title: Save audio record in files with ACRCloud
body: <p>I have a problem with a Android app that call ACRCloud.
  For the work that I need to do, I want to save the recording in a MP3 file but I don't know why it doesn't work.</p>
  
  <p>That's my code :</p>
  
  <pre><code>    File f = null;
      try {
          f = createAudioFile();
      } catch (IOException e) {
          e.printStackTrace();
      }
  
      byte[] data = acrCloudResult.getRecordDataPCM();
  
      if(f.exists()){
          String path = f.getPath();
          FileOutputStream stream = null;
          try {
              stream = new FileOutputStream(path);
          } catch (FileNotFoundException e) {
              e.printStackTrace();
          }
          try {
              stream.write(data);
          } catch (IOException e) {
              e.printStackTrace();
          }
      }
  </code></pre>
