Buggy source:
public void writeMetadata(ByteArrayWithAudioFormatInputStream audioInputStream,WavOutputStream outputStream) throws IOException {
  final InputStreamInfo info=audioInputStream.getInfo();
  final int fileSize=(int)(AndroidWavHelper.INFO_METADATA_SIZE + info.getSoundInfo().length() + (info.getFrameLength() * info.getSampleSize() * info.getChannels()));
  final int chunkSize=AndroidWavHelper.INFO_CHUNK_SIZE;
  final int typeOfEncoding=1;
  final int channels=info.getChannels();
  final int sampleRate=(int)info.getSampleRate();
  final int byterate=(int)info.getSampleRate() * info.getSampleSize();
  final int frameSize=info.getSampleSize() / info.getChannels();
  final int sampleSize=info.getSampleSize() * 8;
  final int dataSize=(int)info.getFrameLength() * info.getSampleSize();
  outputStream.write(AndroidWavHelper.RIFF.getBytes());
  outputStream.writeInt(fileSize);
  outputStream.write(AndroidWavHelper.WAVE.getBytes());
  outputStream.write(AndroidWavHelper.FMT_.getBytes());
  outputStream.writeInt(chunkSize);
  outputStream.writeShortInt(typeOfEncoding);
  outputStream.writeShortInt(channels);
  outputStream.writeInt(sampleRate);
  outputStream.writeInt(byterate);
  outputStream.writeShortInt(frameSize);
  outputStream.writeShortInt(sampleSize);
  if (info.getSoundInfo() != null) {
    outputStream.write(AndroidWavHelper.LIST.getBytes());
    outputStream.writeInt(info.getSoundInfo().length());
    outputStream.write(info.getSoundInfo().getBytes());
  }
  outputStream.write(AndroidWavHelper.DATA.getBytes());
  outputStream.writeInt(dataSize);
}

Fixed version (ground truth):
public void writeMetadata(ByteArrayWithAudioFormatInputStream audioInputStream,WavOutputStream outputStream) throws IOException {
  final InputStreamInfo info=audioInputStream.getInfo();
  final int soundInfoSize=info.getSoundInfo() == null ? 0 : info.getSoundInfo().length();
  final int fileSize=(int)(AndroidWavHelper.INFO_METADATA_SIZE + soundInfoSize + (info.getFrameLength() * info.getSampleSize() * info.getChannels()));
  final int chunkSize=AndroidWavHelper.INFO_CHUNK_SIZE;
  final int typeOfEncoding=1;
  final int channels=info.getChannels();
  final int sampleRate=(int)info.getSampleRate();
  final int byterate=(int)info.getSampleRate() * info.getSampleSize();
  final int frameSize=info.getSampleSize() / info.getChannels();
  final int sampleSize=info.getSampleSize() * 8;
  final int dataSize=(int)info.getFrameLength() * info.getSampleSize();
  outputStream.write(AndroidWavHelper.RIFF.getBytes());
  outputStream.writeInt(fileSize);
  outputStream.write(AndroidWavHelper.WAVE.getBytes());
  outputStream.write(AndroidWavHelper.FMT_.getBytes());
  outputStream.writeInt(chunkSize);
  outputStream.writeShortInt(typeOfEncoding);
  outputStream.writeShortInt(channels);
  outputStream.writeInt(sampleRate);
  outputStream.writeInt(byterate);
  outputStream.writeShortInt(frameSize);
  outputStream.writeShortInt(sampleSize);
  if (info.getSoundInfo() != null) {
    outputStream.write(AndroidWavHelper.LIST.getBytes());
    outputStream.writeInt(info.getSoundInfo().length());
    outputStream.write(info.getSoundInfo().getBytes());
  }
  outputStream.write(AndroidWavHelper.DATA.getBytes());
  outputStream.writeInt(dataSize);
