如何使用 TarsosDSP 获得 MFCC？

我到处搜索，但不知道如何在 Android 上使用 TarsosDSP 提取 MFCC 特征。我知道如何从文件中获取 FFT。 有什么帮助吗？

查看官方github页面

MFCC 测试文件

public class MFCCTest {

//  private static int counter = 0;

    @Test
    public void MFCCForSineTest() throws UnsupportedAudioFileException{
        int sampleRate = 44100;
        int bufferSize = 1024;
        int bufferOverlap = 128;
        final float[] floatBuffer = TestUtilities.audioBufferSine();
        final AudioDispatcher dispatcher = AudioDispatcherFactory.fromFloatArray(floatBuffer, 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) {
                return true;
            }
        });
        dispatcher.run();
    }

}

和 TestUtilities audioBufferSine()

public class TestUtilities {

    /**
     * Constructs and returns a buffer of a two seconds long pure sine of 440Hz
     * sampled at 44.1kHz.
     * 
     * @return A buffer of a two seconds long pure sine (440Hz) sampled at
     *         44.1kHz.
     */
    public static float[] audioBufferSine() {
        final double sampleRate = 44100.0;
        final double f0 = 440.0;
        final double amplitudeF0 = 0.5;
        final double seconds = 4.0;
        final float[] buffer = new float[(int) (seconds * sampleRate)];
        for (int sample = 0; sample < buffer.length; sample++) {
            final double time = sample / sampleRate;
            buffer[sample] = (float) (amplitudeF0 * Math.sin(2 * Math.PI * f0 * time));
        }
        return buffer;
    }
