媒体录音机声音质量差
[英]Media recorder sound have poor quality
问题描述
What i try to do is to record a sound after to upload it into firebase and to retrieve then into reciclerview were i can control the play/stop and the progress.
我尝试做的是在将声音上传到 firebase 后录制声音，然后检索到 reciclerview，我可以控制播放/停止和进度。 Like whatsApp audio messages
The class AudioPlayer its called in the Main activity by pressing a button and return the value to upload the file in firebase.Its work but the sound quality its very poor and its work just in browser or directly in source folder or i can t play it in other formats like THREE_GPP just when i play it directly in the source folder.
public class StartRecordMessage extends AppCompatActivity implements Runnable {
private static String fileName = null;
private MediaRecorder myAudioRecorder;
private MediaPlayer player = null;
private boolean permissionToRecordAccepted = false;
private String[] permissions = {Manifest.permission.RECORD_AUDIO};
private final String TAG = "StartRecordMessageClass";
private String audioName = null;
private String externalStoragePath,externalOutputPath,storagePath;
public StartRecordMessage(MediaRecorder myAudioRecorder) {
this.myAudioRecorder = myAudioRecorder;
}
@Override
public void run() {
startRecording();
}
public String startRecording (){
myAudioRecorder = new MediaRecorder();
myAudioRecorder.reset();
myAudioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
myAudioRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
myAudioRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED))
{
externalStoragePath = Environment.getExternalStorageDirectory().getAbsolutePath();
externalOutputPath = externalStoragePath + File.separator + "/Android/data/test.mp3";
myAudioRecorder.setOutputFile(externalOutputPath);
}
else
{
storagePath = Environment.getDataDirectory().getAbsolutePath();
myAudioRecorder.setOutputFile(storagePath + "/Android/data/test.mp3");
}
try {
Log.i(TAG, "--------------recording started confirmed" + externalOutputPath + storagePath );
myAudioRecorder.prepare();
myAudioRecorder.start();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if (externalOutputPath.isEmpty()){
return storagePath;
}else {
return externalOutputPath;
}
}
Follow method is in the main activity遵循方法在主要活动中
@Override
public void onRecordingCompleted() {
Log.i(TAG, "---------completed");
startThread = new Thread(new StartRecordMessage(myAudioRecorder));
startThread.start();
startRecordMessage = new StartRecordMessage(myAudioRecorder);
audioMessage = startRecordMessage.startRecording();
Log.i(TAG, "recordingCompleted--------------" + audioMessage);
UploadSound(audioMessage);
}
messageListAdapter.notifyDataSetChanged();
}

audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, volume, AudioManager.FLAG_VIBRATE);
}
mp.start();
}
});
} catch(
Throwable e)
{
Log.i("AudioUtil", "Unable to play: " + path, e);
}
}
}
AdapterClass适配器类
holder.playStop.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
clickCount++;
if (clickCount==1) {
isPlayng=true;
holder.playStop.setBackgroundResource(R.drawable.ic_pause);
Log.i(TAG,"audio url---------------" + audio);
audioPlayer = new AudioPlayer();
audioPlayer.play(context,audio);
Log.i(TAG, "Media player ------------"+ clickCount + " is play: " +isPlayng);
}
if (clickCount>1){
isPlayng=false;
clickCount=0;
holder.playStop.setBackgroundResource(R.drawable.ic_play);
Log.i(TAG, "Media player ------------" + clickCount + " is play: " + isPlayng);
}

try add values in your media file.尝试在您的媒体文件中添加值。
exmaple.例如。
// Setup values for the media file
ContentValues values = new ContentValues(4);
long current = System.currentTimeMillis();
values.put(MediaStore.Audio.Media.TITLE, "audio file");
values.put(MediaStore.Audio.Media.DATE_ADDED, (int) (current / 1000));
values.put(MediaStore.Audio.Media.MIME_TYPE, "audio/3gpp");
values.put(MediaStore.Audio.Media.DATA, audiofile.getAbsolutePath());
ContentResolver contentResolver = getContentResolver();
// Construct uris
Uri base = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Uri newUri = contentResolver.insert(base, values);
// Trigger broadcast to add
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, newUri));
Toast.makeText(this, "Added File " + newUri, Toast.LENGTH_LONG).show();
