我想在实时流式传输歌曲的同时在 Android Studio 中逐字节处理音频。似乎无法从 MediaPlayer 类中获取数据。我将不胜感激任何帮助。谢谢!

代替 MediaPlayer 使用 AudioRecord Audio Record - Android Developer

样本:

int sampleRate = 16000;
int bufferSize = AudioRecord.getMinBufferSize(sampleRate, AudioFormat.CHANNEL_CONFIGURATION_DEFAULT, AudioFormat.ENCODING_PCM_16BIT);
AudioRecord audioRecorder = new AudioRecord(
            MediaRecorder.AudioSource.MIC, sampleRate,
            AudioFormat.CHANNEL_IN_MONO,
            AudioFormat.ENCODING_PCM_16BIT,
            bufferSize);
audioRecord.startRecording();        
new Thread(new Runnable() {
    @Override
    public void run() {
        while (mIsRecording) {
            short[] buffer = new short[mBufferSize];
            int readSize = mAudioRecorder.read(buffer, 0, buffer.length);
            // do your stuff here
        }
    }
}).start();
