java - tarsosdsp 运行时无法在其他应用上使用麦克风

Question

我正在尝试使用 tarsosdsp 增加麦克风音量。我尝试使用录音机，但它一直说我的应用程序正在使用麦克风，我需要关闭我的应用程序才能工作。有人可以指导我如何在允许其他应用程序使用麦克风的同时增加麦克风音量吗？这是我的以下代码：

package com.example.microphonebooster;

import android.Manifest;
import android.content.pm.PackageManager;
import android.os.Build;
import android.os.Bundle;
import android.util.Log;
import android.widget.SeekBar;

import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;

import be.tarsos.dsp.AudioDispatcher;
import be.tarsos.dsp.AudioEvent;
import be.tarsos.dsp.AudioProcessor;
import be.tarsos.dsp.GainProcessor;
import be.tarsos.dsp.io.android.AudioDispatcherFactory;

public class MainActivity extends AppCompatActivity {

    private final static String TAG = "SOUND";

    private AudioDispatcher dispatcher;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        dispatcher = AudioDispatcherFactory.fromDefaultMicrophone(22050, 1024, 0);
        requestRecordAudioPermission();
        SeekBar seekBar = (SeekBar) findViewById(R.id.percentage);
        AudioProcessor soundPressureProcessor = new AudioProcessor() {
            @Override
            public boolean process(AudioEvent audioEvent) {

                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        int x = seekBar.getProgress();
                        GainProcessor idk = new GainProcessor(x);
                       Log.d("xd","reached here");
                    }
                });

                return true;
            }

            @Override
            public void processingFinished() {

            }
        };
        dispatcher.addAudioProcessor(soundPressureProcessor);
        new Thread(dispatcher, "Dispatcher").start();
    }

    // see https://developer.android.com/training/permissions/requesting.html
    private void requestRecordAudioPermission() {
        int apiVersion = Build.VERSION.SDK_INT;

        if (apiVersion > Build.VERSION_CODES.LOLLIPOP) {
            ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.RECORD_AUDIO}, 1);
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
        switch (requestCode) {
            case 1: {
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    Log.d(TAG, "Permission granted");
                }
                else {
                    Log.d(TAG, "Permission denied");
                    finish();
                }
            }
        }
    }
}
