想做一个调音器，如何从Mic上获取到音高

// 创建音频调度器
AudioDispatcher dispatcher = AudioDispatcherFactory.fromDefaultMicrophone(sampleRate, bufferSize);
PitchProcessor pitchProcessor = new PitchProcessor(PitchProcessor.Tuning.STANDARD, sampleRate, bufferSize, new PitchProcessor.PitchDetectionHandler() {
    @Override
    public void handlePitch(PitchDetectionResult result) {
        float pitch = result.getPitch();
        // 转换为十二平均律音高
    }
});
dispatcher.addAudioProcessor(pitchProcessor);
