我用

android AudioRecord录制了声音,我想将它转换为ogg vorbis,因为它是免专利的.我试过vorbis-

java beta,但它似乎不起作用或者我犯了一些错误.

这是我的代码：

int frequency = 44100;

int channel = AudioFormat.CHANNEL_IN_STEREO;

int mAudioSource = MediaRecorder.AudioSource.MIC;

int mAudioEncoder = AudioFormat.ENCODING_PCM_16BIT;

try {

final File outputFile = new File(mOutputPath);

DataOutputStream dos = new DataOutputStream(new BufferedOutputStream(new FileOutputStream(outputFile)));

int bufferSize = AudioRecord.getMinBufferSize(frequency, channel, mAudioEncoder);

AudioRecord audioRecord = new AudioRecord(mAudioSource, frequency, channel, mAudioEncoder, bufferSize);

short[] buffer = new short[bufferSize];

audioRecord.startRecording();

while (isRecordStart) {

int bufferReadResult = audioRecord.read(buffer, 0, bufferSize);

for(int i = 0; i < bufferReadResult; i++) {

dos.writeShort(buffer[i]);

}

}

audioRecord.stop();

dos.close();

}

catch (FileNotFoundException e) {

e.printStackTrace();

}

catch (IOException e) {

e.printStackTrace();

}

我将它保存到扩展名为wav的文件中并使用vorbis-java编码进行编码,但输出只是zzz …….

如何在android中将此编码为ogg vorbis？
