如何使用

初始化

init

/**
* 参数1： Application 实例
* 参数2： 是否打印日志   
*/
RecordManager.getInstance().init(MyApp.getInstance(), false);

在清单文件中注册Services

<service android:name="com.zlw.main.recorderlib.recorder.RecordService" />

确保有录音权限

配置录音参数

修改录音格式(默认:WAV)

 RecordManager.getInstance().changeFormat(RecordConfig.RecordFormat.WAV);

修改录音配置

     RecordManager.getInstance().changeRecordConfig(recordManager.getRecordConfig().setSampleRate(16000));
     RecordManager.getInstance().changeRecordConfig(recordManager.getRecordConfig().setEncodingConfig(AudioFormat.ENCODING_PCM_8BIT));

修改录音音源

     RecordManager.getInstance().setSource(RecordConfig.SOURCE_MIC); // 麦克风
     RecordManager.getInstance().setSource(RecordConfig.SOURCE_SYSTEM); //系统内录

修改录音文件存放位置（默认sdcard/Record）

   RecordManager.getInstance().changeRecordDir(recordDir);

录音状态监听

RecordManager.getInstance().setRecordStateListener(new RecordStateListener() {
   @Override
   public void onStateChange(RecordHelper.RecordState state) {
       }
   }

   @Override
   public void onError(String error) {
   }
});

录音结果监听

RecordManager.getInstance().setRecordResultListener(new RecordResultListener() {
   @Override
   public void onResult(File result) {
   }
});

声音大小监听

 RecordManager.getInstance().setRecordSoundSizeListener(new RecordSoundSizeListener() {
    @Override
    public void onSoundSize(int soundSize) {
    }
});

音频数据监听

  recordManager.setRecordDataListener(new RecordDataListener() {
     @Override
     public void onData(byte[] data) {
     }
 });

音频可视化数据监听

   recordManager.setRecordFftDataListener(new RecordFftDataListener() {
      @Override
      public void onFftData(byte[] data) {
          audioView.setWaveData(data);
      }
    });

录音控制

开始录音
```
RecordManager.getInstance().start();
```
暂停录音
```
RecordManager.getInstance().pasue();
```
恢复录音
```
RecordManager.getInstance().resume();
```
停止
```
RecordManager.getInstance().stop();
```

zlwaudiorecorder's Issues

重复录制会提示，录音文件空闲中，只能录制一次，请问一下这是什么原因

录制mp3的时候没有回调问题触发

录制MP3的时候，pause后stop没有回调，而且会把录音合并到上一次的录音里面

No implementation found for void com.zlw.main.recorderlib.recorder.mp3.Mp3Encoder.init

大神，这个是怎么回事啊

Thanks for this great project, and which is the open source agreement?

关于getMaxAmplitude()函数

你好，MediaRecorder里提供了getMaxAmplitude()函数，那使用AudioRecord录音的时候怎么获取振幅呢？网上找了比较多的方法，发现和MediaRecorder里提供的数据有较大差别。
多谢

java.lang.RuntimeException:Unable to start service com.zlw.main.recorderlib.recorder.RecordService@d1318b0 with Intent { cmp=com.yuanli.mvpuscs/com.zlw.main.recorderlib.recorder.RecordService (has extras) }: java.lang.NullPointerException: Attempt to invoke virtual method 'char[] java.lang.String.toCharArray()' on a null object reference

仓库引用不到

录音结束的时候会报异常java.io.IOException: Stream Closed

java.io.IOException: Stream Closed
在RecordHelper.java:505
关闭资源的时候把两个位置调换一下就可以了
try {
if (fos != null) {
fos.close();
}
if (outputStream != null) {
outputStream.close();
}
} catch (IOException e) {
e.printStackTrace();
}
改成
try {
if (outputStream != null) {
outputStream.close();
}
if (fos != null) {
fos.close();
}
} catch (IOException e) {
e.printStackTrace();
}
大佬可以把这个地方优化下

停止录音后结果没监听到

多次调用录音会报错，麻烦帮忙解决一下

我多次录制音频文件，会发生如下错误（jar里面报的错）：
03-12 13:37:49.709 1323-1727/com.ycsoft.smartbox E/^_^RecordHelper=============: length=1536; regionStart=0; regionLength=-3

第一次录制成功，录完以后，再录制第二个，结果就出现录音出错了，然后就是如上的log，麻烦帮忙看看呢？

测试过程偶尔会遇到崩溃的现象报错如下

AudioView有些地方不懂，能给个联系方式请教一下吗？

请问使用MediaPlayer无法播放MP3音频是什么情况？

请问如何设置录音文件名。

如题，只可以设置路径吗？可以设置文件名吗？或者是不是只能录制结束后自己重命名？

滴滴

能不能留下一个联系方式....有问题想请教

android 8.0+服务不能在后台运行问题

java.lang.IllegalStateException: Not allowed to start service Intent { cmp=com.zlw.main.recorderlib.recorder.RecordService

Caused by: java.lang.IllegalStateException: Not allowed to start service Intent { cmp=.../com.zlw.main.recorderlib.recorder.RecordService (has extras) }: app is in background uid UidRecord{25d39c9 u0a270 SVC bg:+1m0s49ms idle change:idle procs:2 seq(0,0,0)}

能否提供设置最短录音时间/最长录音时间，并通知监听

在录音过程中能否获取音频文件的时长吗？有这样实时的监听接口吗

这中需求相对来说属于比较常规需求了。期待回复

大神，需求需要两种格式的文件mp3和wav，这个可以直接转么

后台录音采集数据，为什么会有一个唤醒锁卡住的问题？大神能指点一下吗？

我们的需求是要在后台录音，记录用户的声音，但是在使用过程中发现在后台时会有一个部分唤醒锁卡住，weak lock，能指点一下吗？

怎么获取音频时间

录制通话的时候，录音文件播放出来声音很小

要靠近手机话筒位置才听得到，音量已经开最大了，大佬有没有办法可以设置调高录制的音量。

Android 10 录音失败

在Android 9或以下的设备录音没有问题，在Android 10上录音会提示录音失败

可以设置录音最大时间限制吗

setRecordFftDataListener不回调

我在录音的时候出现不回调，看来下你的源码，发现setRecordFftDataListener不回调的原因是
recordManager.setRecordDataListener(data -> {
Log.e("TAG", "data长度：" + data.length);
Log.e("TAG", "data::" + getFloat(data));
});
长度都是640 没有大于某个值就不回调，我再看了下返回的byte数组全是-127之类的基本没啥变化，是我使用的方式不对么？因为我需要用到音频的数据，所以把你这些监听全打印出来，但是好想数据是有问题的。

播放音频的时候也能使用音波动画效果吗？

很感谢作者，目前在使用这个库录mp3，请问播放的时候怎么配合这个音波动画呢？

stop方法调用问题

感谢您的分享，我在测试的时候发现stop方法在调用的时候需要在pause的状态下才能执行，不然线程中会一直打印日志，所以建议在调用stop方法之前，先调用pause方法

可以修改文件名字吗

可以修改文件得名字吗不想使用默认得名字

华为p30 录音不能正常录音，且波形不显示

华为p30

安卓10录音崩溃

Unable to start service com.zlw.main.recorderlib.recorder.RecordService@a0c6921 with Intent { cmp=com.lovol.njgj/com.zlw.main.recorderlib.recorder.RecordService (has extras) }: java.lang.NullPointerException
是service启动在安卓10的适配问题？

采集的音量db数太少。

测试了一下，获取10个竟然需要700多毫秒，这样的话想做一个波形图很不平滑，有没有办法在同样的时间采集到更多的db数呢？

5 com.zlw.main.recorderlib.recorder.b$a.run(RecordHelper.java:273)

感谢您的分享，采用您的方式做mp3转码，后来发现在Mp3EncodeThread类的140行ChangeBuffer构造方法传值过程中采用了clone方法，导致一个多小时后内存到了500多M，现在是把clone去掉了

可以处理一下降噪、回声吗？

我有初始化，但是还是报错初始化失败

1， RecordManager.getInstance().init(ChatApplication.appLication,true)

2，RecordManager.getInstance().start()

哪个方法是获取文件时长的？

能否提供指定文件名功能

我的业务要求是只保留最新的录音文件，文件没有就创建新的，可以覆盖旧的文件，谢谢！

你好，我想要在计算音量分贝值时经过A计权和1/3倍频程的换算。请问大神有没有经验能指点一下，谢谢~

添加依赖一直失败

How to compress WAV file?

Hi,

Thanks for the great library, how can i compress the file size of wav format?

录音文件路径，没有提供外接api啊

录音文件路径，没有提供外接api啊，没法获取当时录音的文件

提升码率

首先大佬的库很不错下载了看了下封装的也可以
想问下 pcm转MP3的时候 MP3的码率只有20多我想提升到100多应该怎么办呢

实时音量不准确吧？？？

RecordManager.getInstance().setRecordSoundSizeListener(new RecordSoundSizeListener() {
    @Override
    public void onSoundSize(int soundSize) {
    }
});

音量一直是在50-70之间徘徊。不管是一点声音都没有，还是声音很大，曲线都一样。
