Java Android中的默认录音语音
我注意到Android默认的语音记录器可以感知你的声音和声音有多大Java Android中的默认录音语音,java,android,Java,Android,我注意到Android默认的语音记录器可以感知你的声音和声音有多大 我可以出于目的使用它吗?或者我如何编写代码来感知Android中声音的响度。可以使用Android.media.MediaRecorder录制。本页列出了所有API。这会解决你所有的问题。 示例代码 MediaRecorder recorder = new MediaRecorder(); recorder.setAudioSource(MediaRecorder.AudioSource.MIC); recorder.se
我可以出于目的使用它吗?或者我如何编写代码来感知Android中声音的响度。可以使用Android.media.MediaRecorder录制。本页列出了所有API。这会解决你所有的问题。 示例代码
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(PATH_NAME);
recorder.prepare();
recorder.start(); // Recording is now started
...
while(recordingNotOver)
{
int lastMaxAmplitude = recorder.getMaxAmplitude();
// you have the value here in lastMaxAmplitude, do what u want to
}
recorder.stop();
recorder.reset(); // You can reuse the object by going back to setAudioSource() step
recorder.release(); // Now the object cannot be reused
我放了一些密码
这是主课
final AudioRecorder recorder = new AudioRecorder("/calls");
try {
recorder.start();
try {
this.wait(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
recorder.stop();
} catch (IOException e) {
e.printStackTrace();
}
}
}
助手类是:
public class AudioRecorder {
final MediaRecorder recorder = new MediaRecorder();
final String path;
public AudioRecorder(String path) {
this.path = sanitizePath(path);
}
private String sanitizePath(String path) {
if (!path.startsWith("/")) {
path = "/" + path;
}
if (!path.contains(".")) {
path += ".3gp";
}
//This is the command I would like to change, because I want to save the audio
//files in the internal memory instead of the SD card
return Environment.getDataDirectory().getAbsolutePath() + path;
}
public void start() throws IOException {
String state = android.os.Environment.getExternalStorageState();
if(!state.equals(android.os.Environment.MEDIA_MOUNTED)) {
throw new IOException("SD Card is not mounted. It is " + state + ".");
}
// make sure the directory we plan to store the recording in exists
File directory = new File(path).getParentFile();
if (!directory.exists() && !directory.mkdirs()) {
throw new IOException("Path to file could not be created.");
}
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
}
public void stop() throws IOException {
recorder.stop();
recorder.release();
}
}
谢谢,我还发现了这个开源项目
