如何使用 AudioRecorder 中的录制音频Android

试试这个......public class Audio_Record extends Activity {private static final int RECORDER_SAMPLERATE = 8000;private static final int RECORDER_CHANNELS = AudioFormat.CHANNEL_IN_MONO;private static final int RECORDER_AUDIO_ENCODING = AudioFormat.ENCODING_PCM_16BIT;private AudioRecord recorder = null;private Thread recordingThread = null;private boolean isRecording = false;@Overridepublic void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); setButtonHandlers(); enableButtons(false); int bufferSize = AudioRecord.getMinBufferSize(RECORDER_SAMPLERATE, RECORDER_CHANNELS, RECORDER_AUDIO_ENCODING); }private void setButtonHandlers() { ((Button) findViewById(R.id.btnStart)).setOnClickListener(btnClick); ((Button) findViewById(R.id.btnStop)).setOnClickListener(btnClick);}private void enableButton(int id, boolean isEnable) { ((Button) findViewById(id)).setEnabled(isEnable);}private void enableButtons(boolean isRecording) { enableButton(R.id.btnStart, !isRecording); enableButton(R.id.btnStop, isRecording);}int BufferElements2Rec = 1024; // want to play 2048 (2K) since 2 bytes we use only 1024int BytesPerElement = 2; // 2 bytes in 16bit formatprivate void startRecording() { recorder = new AudioRecord(MediaRecorder.AudioSource.MIC, RECORDER_SAMPLERATE, RECORDER_CHANNELS, RECORDER_AUDIO_ENCODING, BufferElements2Rec * BytesPerElement); recorder.startRecording(); isRecording = true; recordingThread = new Thread(new Runnable() { public void run() { writeAudioDataToFile(); } }, "AudioRecorder Thread"); recordingThread.start();} //convert short to byteprivate byte sData) { int shortArrsize = sData.length; byte; for (int i = 0; i 《 shortArrsize; i++) { bytes & 0x00FF); bytes 》》 8); sData = 0; } return bytes;}private void writeAudioDataToFile() { // Write the output audio in byte String filePath = "/sdcard/voice8K16bitmono.pcm"; short sData; FileOutputStream os = null; try { os = new FileOutputStream(filePath); } catch (FileNotFoundException e) { e.printStackTrace(); } while (isRecording) { // gets the voice output from microphone to byte format recorder.read(sData, 0, BufferElements2Rec); System.out.println("Short wirting to file" + sData.toString()); try { // // writes the data to file from buffer // // stores the voice buffer byte bData = short2byte(sData); os.write(bData, 0, BufferElements2Rec * BytesPerElement); } catch (IOException e) { e.printStackTrace(); } } try { os.close(); } catch (IOException e) { e.printStackTrace(); }}private void stopRecording() { // stops the recording activity if (null != recorder) { isRecording = false; recorder.stop(); recorder.release(); recorder = null; recordingThread = null; }}private View.OnClickListener btnClick = new View.OnClickListener() { public void onClick(View v) { switch (v.getId()) { case R.id.btnStart: { enableButtons(true); startRecording(); break; } case R.id.btnStop: { enableButtons(false); stopRecording(); break; } } }};@Overridepublic boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK) { finish(); } return super.onKeyDown(keyCode, event);}}

audio recorder现在录音文件存在哪个目录

录音时mic（自己）和speaker（对方）是分开录的，路径在/var/mobile/Library/Application Support/UltimateCallRecorder需要导出到邮件时由程序把两个文件合成成为一个文件。发送或者取消发送后合成的录音文件会被删除，所以要在删除之前提取出来。方法:录音后打开audio recorder程序，点一下你要导出的录音文件，再点左上角的分享按钮，然后agree，就会出现mail的图标，用户可以通过mail分享。此时不要点mail图标，按home键后台，打开ifile，打开var/tmp路径，发现里面会有两个m4a的文件，这两个文件是一样的，随便备份一个出来就好了。备份好了就可以回到程序取消发送邮件了。

请教如何将audiorecorder录音文件导出

　　将audiorecorder录音文件导出的方法　　一．前提是手机越狱了，并下载安装好Audio Recorder这个插件，并有录音文件。只要点击recorder进去看一下有没有文件就知道了。　　二．利用【PP助手】，打开助手之后，连接上手机，并点击【文件】。　　三．点击【文件】之后，再点击【文件系统（越狱）】，这里需要要注意一下，一定是点击【文件系统（越狱）】，并不是第一个【文件系统（用户）】哦。　　四．接着就是在右边的文件夹中，找到【var】这个文件夹，并双击进入。　　五．在【var】文件夹中找到【mobile】文件夹，并双击【mobile】。　　六．在【mobile】中找到【Documents】文件夹，并双击【Documents】。　　七．双击【AudioRecorder】。　　八．所有录音文件都在这里了。不过要注意，callSpeaker才是录音的原文件，只要把callSpeaker的录音文件导出来就可以使用了。当然，导出的格式是caf，这时大家可以通过一些转换工具，把caf的格式转换成mp3就可以了。
