[ ![Download](https://api.bintray.com/packages/wangcongwu123/maven/LingoRecorder/images/download.svg) ](https://bintray.com/wangcongwu123/maven/LingoRecorder/_latestVersion) # Features 1. 多线程机制保证处理能力和 PCM 数据的完整性。 2. 抽象出 AudioProcessor 来注入 Recorder 中以支持录音和处理的分离。 3. 提供 WavFileRecorder 以支持以文件来替代录音器生成录音数据。 4. 提供 aidl 接口方便在另一个进程中处理录音数据。 # Sample ## LingoRecorder 的使用 只需简单的三步操作即可: ``` lingoRecorder = new LingoRecorder(); lingoRecorder.setOnRecordStopListener(new LingoRecorder.OnRecordStopListener() { @Override public void onRecordStop(Throwable throwable, Result result) { //any execeptions occur during recording will be received at here. //you can get duration and output file from Result. } }); lingoRecorder.setOnProcessStopListener(new LingoRecorder.OnProcessStopListener() { @Override public void onProcessStop(Throwable throwable, Map map) { //any execeptions occur during processing will be received at here. //you can get any processors you inject into recorder. //the callback will be invoked after "onRecordStop". } }); ``` 效果图: ![image](https://raw.github.com/lingochamp/LingoRecorder/develop/demo/images/record.gif) ## 自定义 AudioProcessor 的使用 可以实现 AudioProcessor 来自定义自己的处理器： ``` public interface AudioProcessor { void start() throws Exception; void flow(byte[] bytes, int size) throws Exception; boolean needExit(); void end() throws Exception; void release(); } ``` 效果图: ![image](https://raw.github.com/lingochamp/LingoRecorder/develop/demo/images/custom_processors.gif) ## 将 AudioProcessor 运行在一个独立的进程中 LingoRecorder 提供了 aidl 接口以支持在一个独立的进程中运行 AudioProcessor。示例中自定义了一个 `LocalScorerProcessor` 运行在 "score" 进程中。 ## Flac encoder 示例中也演示了一个使用 `MediaCodec` 进行 Flac 编码的 AudioProcessor。此示例是为了向有硬编码需求的用户提供一个样例。 ## 计算/监听音量 设置音量监听器： ``` //只设置 OnVolumeListener 的时候，计算音量的方式使用的是一个默认的内部实现 //内部默认实现的返回值是[0, 90]的分贝值 lingoRecorder.setOnVolumeListener(new OnVolumeListener() { @Override public void onVolume(double volume) { } }); //也可以提供自己的计算音量的实现 lingoRecorder.setOnVolumeListener(new OnVolumeListener() { @Override public void onVolume(double volume) { } }, new IVolumeCalculator() { @Override public double onAudioChunk(byte[] chunk, int size, int bitsPerSample) { return 0; } }); ``` Demo 中提供了相关示例，效果图： ![image](https://raw.github.com/lingochamp/LingoRecorder/develop/demo/images/volume.gif) # 在项目中引用 Gradle: ``` compile 'com.liulishuo.engzo:lingo-recorder:1.2.5' ``` # Pull Request 欢迎各位基于 develop 分支进行 pull request。 License ------- Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
