AudioRecorder

使用

Recorder recorder = new Recorder.Builder(this)
 .setChannel(1)//通道数,默认1
 .setSampleRate(16000)//采样率,默认16000
 .setBitsPerSample(16)//采样位,默认16
 .setFileFormat(FileFormat.Format.PCM)//设置录音格式(PCM,WAV,AAC,AMR),默认pcm
 .setOutputPath("sdcard/RecordFile")//设置输出文件路径,默认是app的cachePath
 .setOutputFileName("record.wav")//设置输出文件名,默认文件名格式是yyyyMMdd_HHmm_ss.suffix
 .setRecordTimeout(1000*10)//设置录音时长,默认0
 .setBitRate(96000)//aac编码可设置比特率,默认96000
 .setBuffSize(1024)//录音缓冲区大小,默认是2倍AudioRecord.getMinBufferSize计算的大小
 .setSaveOutputFile(false)//是否保存录音数据到文件,默认true
 //设置自定义编码器AudioProcessor
 .setAudioProcessor("wav", new WAVProcessor() {
 @Override
 public void onBegin(RandomAccessFile writer, Recorder.Config config) throws IOException {
 super.onBegin(writer, config);
 }
 @Override
 public void onEnd(RandomAccessFile writer) throws IOException {
 super.onEnd(writer);
 }
 @Override
 public int onRead(AudioRecordEngine.PCMReader reader, byte[] buffer) throws IOException {
 return super.onRead(reader, buffer);
 }
 @Override
 public void onAudioChunk(RandomAccessFile writer, byte[] chunk, int readLen) throws IOException {
 super.onAudioChunk(writer, chunk, readLen);
 }
 })
 .build();
recorder.start();
recorder.stop();
recorder.cancel();
recorder.pause();
recorder.release();
recorder.isRecording();
recorder.setVolumeListener(new OnVolumeListener() {
 @Override
 public void onVolume(double volume) {
 //输出录音音量
 }
});
recorder.setRecordListener(new OnRecordListener() {
 @Override
 public void onState(int state, String msg) {
 //输出状态OnRecordListener.STATE_START,OnRecordListener.STATE_ERROR ...
 }
 @Override
 public void onResult(String path, long duration_s, long size_k) {
 //输出结果
 }
});
recorder.setOnAudioChunkListener(new OnAudioChunkListener() {
 @Override
 public void onAudioChunk(byte[] chunk) {
 //输出编码后的数据
 }
});
