Android 音频采集/音频播放【AudioTrack、AudioRecord】

项目中遇到需求，采集音频上传至公司编译的sdk内，播放sdk传递过来的音频，所以自行实现了一个采集音频与播放音频的方法

代码：

import android.Manifest
import android.app.Activity
import android.content.pm.PackageManager
import android.media.AudioFormat
import android.media.AudioManager
import android.media.AudioRecord
import android.media.AudioTrack
import android.media.MediaRecorder
import android.media.audiofx.AcousticEchoCanceler
import android.util.Log
import android.widget.LinearLayout
import androidx.core.app.ActivityCompat
import com.brainmed.mvdplayer.OpenTalkingBean
import com.google.gson.Gson
import com.lzf.easyfloat.EasyFloat
import com.mohism.medtion.ext.gone
import com.mohism.medtion.ext.visible
import com.mohism.medtion.ui.elab.player.NyhMvdPlayerManger
import com.mohism.medtion.ui.elab.player.enums.NyhMvdErrorEnum
import java.io.ByteArrayOutputStream
import java.util.Arrays
import java.util.concurrent.LinkedBlockingQueue

private val outputStream = ByteArrayOutputStream()

private var audioPlayThread: Thread? = null

companion object {

@Volatile

@JvmStatic
fun instance(): NyhMvdVoiceManger {
// 双重检查锁定，确保线程安全
if (mInstance == null) {
synchronized(this) {
if (mInstance == null) {
mInstance = NyhMvdVoiceManger()
}
}
}
return mInstance!!
}
}
