# RxHarmonyAudio
Adaptation of RxAndroidAudio(https://github.com/Piasy/RxAndroidAudio) to Harmony OS.An Audio encapsulation library, with part Rx support.
本项目是基于开源项目Piasy/RxAndroidAudio进行鸿蒙化的移植和开发的，可以通过地址https://github.com/Piasy/RxAndroidAudio 追踪到原安卓项目版本。
## 项目介绍
## (Project Introduce)
### 项目名称（Project Name:）：RxHarmonyAudio
### 功能：(Functions:)
1. 实现音频文件录制和播放
(1.record and play audio file)
2. 实现音频流文件录制和播放
(2.record and play audio stream file)
3. 变声播放录音文件
(3.voice changing play)
### 项目移植状态：(project complete status:)
1. 主要功能已经移植；
(1.mainly functions completed)
2. 测试Demo可以正常使用；
(2.Demo for test can be use)
### 项目作者和维护人：TS
### 编程语言：java
## 使用说明(How to use:)
1. 下载或自行编译生成RxHarmonyAudio的.har文件，文件路径为：entry/libs/rxharmonyaudio.har。
(1.Download or compile RxHarmonyAudio.har file yourself,the sample har file location:entry/libs/rxharmonyaudio.har.)
2. 自行编译时，需要注意要自行添加签名。
(2.You should pay attention to add the Signature file to project structure when you compile the project your self.)
3. 导入你的OHOS项目模块的**./libs**中。
(3.import your OHOS projct module to **./libs** of your project.)
4. 在模块下的**build.gradle**中确认依赖**./libs**下的.har包，``implementation fileTree(dir: 'libs', include: ['*.jar', '*.har'])``。
(4.add ``implementation fileTree(dir: 'libs', include: ['*.jar', '*.har'])`` into **build.gradle** of the moudle you perfer.)
5. 在代码中使用。
(5.use the classes providered with the Har.)
## 代码使用(Usage)
#### 录制音频文件(Record to file)
```java
mAudioRecorder = AudioRecorder.getInstance();
mAudioFile = new File(
Environment.getExternalStorageDirectory().getAbsolutePath() +
File.separator + System.nanoTime() + ".file.m4a");
Source source = new Source();
source.setRecorderAudioSource(Recorder.AudioSource.MIC);
AudioProperty audioProperty = new AudioProperty.Builder()
.setRecorderSamplingRate(AUDIO_SAMPLE_RATE_HZ)
.setRecorderBitRate(AUDIO_BIT_RATE_HZ)
.setRecorderAudioEncoder(Recorder.AudioEncoder.AAC)
.build();
StorageProperty storageProperty = new StorageProperty.Builder()
.setRecorderFile(mAudioFile)
.setRecorderMaxDurationMs(-1)
.setRecorderMaxFileSizeBytes(-1)
.build();
mAudioRecorder.prepareRecord(source, Recorder.OutputFormat.MPEG_4,
audioProperty, storageProperty);
mAudioRecorder.startRecord();
// ...
mAudioRecorder.stopRecord();
```
#### 播放音频文件(Play a file)
Playconfig 中可以设置音频源，设置音量，或者播放循环：
With PlayConfig, to set audio file or audio resource, set volume, or looping:
```java
mRxAudioPlayer.play(PlayConfig.file(audioFile).looping(true).build())
.subscribeOn(Schedulers.io())
.observeOn(HarmonySchedulers.mainThread())
.subscribe(new Observer() {
@Override
public void onSubscribe(final Disposable disposable) {
}
@Override
public void onNext(final Boolean aBoolean) {
// prepared
}
@Override
public void onError(final Throwable throwable) {
}
@Override
public void onComplete() {
// play finished
// NOTE: if looping, the Observable will never finish, you need stop playing
// onDestroy, otherwise, memory leak will happen!
}
});
```
#### PlayConfig 的完整示例(Full example of PlayConfig)
```java
PlayConfig.file(audioFile) // play a local file
//.res(getApplicationContext(), R.raw.audio_record_end) // or play a raw resource
.looping(true) // loop or not
.leftVolume(1.0F) // left volume,but harmony Player not support left volume and right volume separated.
.rightVolume(1.0F) // right volume,but harmony Player not support left volume and right volume separated.
.build(); // build this config and play!
```
#### 录制音频流文件 (Record a stream)
```java
mOutputFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath() +
File.separator + System.nanoTime() + ".stream.m4a");
mOutputFile.createNewFile();
mFileOutputStream = new FileOutputStream(mOutputFile);
mStreamAudioRecorder.start(new StreamAudioRecorder.AudioDataCallback() {
@Override
public void onAudioData(final byte[] data,final int size) {
if (mFileOutputStream != null) {
try {
mFileOutputStream.write(data, 0, size);
} catch (IOException e) {
e.printStackTrace();
}
}
}
@Override
public void onError() {
new EventHandler(EventRunner.getMainEventRunner()).postSyncTask(new Runnable() {
@Override
public void run() {
new ToastDialog(StreamAbility.this).setText("Record fail").setDuration(DIALOG_DURATION).show();
mBtnStart.setText("Start");
mIsRecording = false;
}
});
}
});
```
#### 播放音频流文件 (Play a stream)
```java
Observable.just(mOutputFile).subscribeOn(Schedulers.io()).subscribe(new Action1() {
@Override
public void call(File file) {
try {
mStreamAudioPlayer.init();
FileInputStream inputStream = new FileInputStream(file);
int read;
while ((read = inputStream.read(mBuffer)) > 0) {
mStreamAudioPlayer.play(mBuffer, read);
}
inputStream.close();
mStreamAudioPlayer.release();
} catch (IOException e) {
e.printStackTrace();
}
}
});
```
#### 变音播放 (Change the sound effect in stream mode)
``` java
mStreamAudioPlayer.play(
mAudioProcessor.process(mRatio, mBuffer, StreamAudioRecorder.DEFAULT_SAMPLE_RATE),
read);
```
