Question

在这个例子中（答案）： How to get MFCC with TarsosDSP?

他们展示了如何在浮动数组中使用android @Test中的MFCC，我试图将它与来自麦克风的数据一起使用：

    int sampleRate = 44100;
    int bufferSize = 8192;
    int bufferOverlap = 128;
    final AudioDispatcher dispatcher = AudioDispatcherFactory.fromDefaultMicrophone(sampleRate, bufferSize, bufferOverlap);
    final MFCC mfcc = new MFCC(bufferSize, sampleRate, 40, 50, 300, 3000);
    dispatcher.addAudioProcessor(mfcc);
    dispatcher.addAudioProcessor(new AudioProcessor() {

        @Override
        public void processingFinished() {
        }

        @Override
        public boolean process(AudioEvent audioEvent) {
            float[] audioBuffer = audioEvent.getFloatBuffer();
            textView.setText(Arrays.toString(audioBuffer));
            return true;
        }
    });
    dispatcher.run();

我想打印输出，但这不打印任何东西，我无法调试它！我需要帮助。

编辑：

经过一番努力之后，我将代码改为:(但仍然无法正常工作）

    int sampleRate = 44100;
    int bufferSize = 8192;
    int bufferOverlap = 128;
    final AudioDispatcher dispatcher = AudioDispatcherFactory.fromDefaultMicrophone(sampleRate, bufferSize, bufferOverlap);
    final MFCC mfcc = new MFCC(bufferSize, sampleRate, 40, 50, 300, 3000);
    dispatcher.addAudioProcessor(mfcc);
    dispatcher.addAudioProcessor(new AudioProcessor() {

        @Override
        public void processingFinished() {
            float audio_float[] = mfcc.getMFCC();
            textView.setText(Arrays.toString(audio_float));

        }

        @Override
        public boolean process(AudioEvent audioEvent) {
            mfcc.process(audioEvent);
            final float audio_float[] = mfcc.getMFCC();
            //textView.setText(Arrays.toString(audio_float));
            textView.setText("TESTING");
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    textView.setText(Arrays.toString(audio_float));

                }
            });
            return true;
        }
    });
    new Thread(dispatcher,"Audio MFCC").start();

编辑：完成：

    dispatcher.addAudioProcessor(new AudioProcessor() {

        @Override
        public void processingFinished() {
            textView.setText("Finish");
        }

        @Override
        public boolean process(AudioEvent audioEvent) {

            mfcc.process(audioEvent);
            final float audio_float[] = mfcc.getMFCC();
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    textView.setText(Arrays.toString(audio_float));
                    textView.invalidate();
                }
            });
            return true;
        }
    });
    new Thread(dispatcher,"Audio MFCC").start();
}
