• Play audio .amr on Windows 8

  My collection of files audio .amr, recorded on my cell phone, does not play in QuickTime, or Windows Media Player 12 after the upgrade to Windows 8 Pro.

  I installed the http://shark007.net/win8codecs.htmlShark007 codec pack.  The option "make a multimedia" in the settings app makes files perfectly, but WMP12 does not produce any audio.  GraphStudioNext reported that splitter audio decoder AVL and AVL are used and also plays the media.

  I tried fiddling with different parameters, but you cannot make it work.  Someone with a similar configuration can confirm?

  Well, with the settings suggested on the Shark007 codec pack, I am able to play these files without any conversion...

• How to record and play Audio

  Hello

  I want a code example to learn how to record audio and play audio recorded

  Can anyone help me regarding this?

  Thank you

  Pounet

  Try this code, it works for me.

  To record the audio. Note that this code records audio in the device memory. Just change the url to save the code in the sd card.

  try {}
  Reader = Manager.createPlayer ("capture://audio?encoding=amr");
  Player.Realize ();
              
  RC = (RecordControl) player.getControl ("RecordControl");
  BT = new ByteArrayOutputStream();
  rc.setRecordStream (bt);
  FC = (FileConnection)Connector.open("file:///store/home/user/RecordedFiles/audio1.amr");
  {if (!) FC. Exists())}
  FC. Create();
  }
  OT = fc.openDataOutputStream ();
  rc.setRecordStream (ot);
  rc.startRecord ();
  Player.Start ();

  } catch (Exception e) {}
  e.printStackTrace ();
  }

  To stop and play the audio. Copy the following code,

  try {}
  RC.Commit ();
              
  data = bt.toByteArray ();
  BT. Close();
  Player.Close ();
            
              
  BI = new ByteArrayInputStream (data);
              
              
  Player = Manager.createPlayer (bi, "audio/amr");

  Player.Realize ();

  Player.Start ();

  } catch (Exception e) {}
  e.printStackTrace ();
  }

• Once its saved audio playback

  Can someone tell me how I should play an audio recorded? I'm recording in default AMR format. The data are stored in an array of byte []. Now, I want to play these data once registration is completed. Please can someone give me a code example of how this could be done.

  My code is,

  Reader = Manager.createPlayer ("capture://audio");

  Player.Realize ();

  rcControl = player.getControl ("RecordControl") (RecordControl);

  output = new ByteArrayOutputStream();

  rcControl.setRecordStream (output);

  rcControl.startRecord ();

  Player.Start ();

  Once I hit the stop button, it does the following:

  rcControl.commit ();

  data = outout.toByteArray ();

  output. Close();

  Player.Close ();

  Now, when I hit the play button,

  Reader = Manager.createPlayer (new String (data));  Note: data are a byte array

  drive. Realize();

  Player.prefetch ();

  Player.Start ();

  But when I hit the play button, the player does not have these data. Can anyone help me please with this. I'm really stuck with it. Can someone give me a code to play this audio recorded? Thank you.

  Kind regards

  David

  I did not try it, but I think it goes something like this:

  (data [] byte)

  ByteArrayInputStream bi = new ByteArrayInputStream (data);

  Reader = Manager.createPlayer (bi, "audio/amr");

• combined audio path definition does not, even if no exception is raised.

  Hi all

  I read a stream of UDP data and then read it over the phone. Ideally, the sound should go to the internal speaker, as in the case of telephone calls. But what I hear, it's always the f same speaker external I put the audio track to be combined. No exception is raised, no error.

  Someone at - it had the same problem? Is there a solution?

  See my code below and the comments.

  Thanks for your help

  ------------------------------------------------------------------------------

  create my own source of stream data

  playerStreamDataSource = new PlayerStreamDataSource("audio/amr");

  try {}

  Player = Manager.createPlayer (playerStreamDataSource);

  player.addPlayerListener (this);

  player.setLoopCount (1);

  Player.Realize ();

  } catch (Exception e) {}

  System.out.println ("ERROR:" + e);

  }

  There is certainly a difference between the listener and the way audio speaker. If I remember correctly, adjust the volume to 100 in headset mode at all does the intensity that you get when you activate the speaker and all the volume to 100.

  Try switching the speaker using AudioPathControl.toggleSpeakerphone ().

  PS if there is another audio player at the same time, you must use AudioPathControl this player instead of your drive.

• MS Movie Maker - codecs

  MS Vista - using Movie Maker 6.0, I have problems with the audio.  Any video imported into Movie Maker is not audio with it.  I'm more interested, however, get a few Notes of the voice of my Blackberry in Movie Maker (file extension is .amr).  DivX won't, and I also had problems with WMEncoder.  Any ideas on how to get my .amr files in Movie Maker?

  ================================
  Try to use the following free software to convert the .amr
  files to the .wma format.

  (FWIW... it's always a good idea to create a system)
  Restore point before installing software or updates)

  Format Factory
  http://www.pcfreetime.com/
  (FWIW... you can uncheck
  all the boxes on the last screen)

  After downloading and installing Format Factory...
  Open the program and choose an output folder...
  (this is where you will find your files when they are
  converted)

  Drag and drop your clips audio .amr on main screen...

  Select "while"WMA"/ OK...

  Click on... Beginning... in the toolbar...

  That should do it...

• ULaw and alaw record and play G711

  I want to be able to capture and play directly to the a - law and u - law format.  I have read several posts on how to put the reader (capture in my case) in amr and pcm mode.

  Capture of AMR and PCM is not a problem, but the correct string of capture to capture the u - law data is unknown to me.

  for the record:

  capture://audio? Encoding = PCM works, also tried something like:

  capture://audio? Encoding = PCMU (does not), also tried to replace with pcmu, ulaw, audio/x-ulaw

  capture://audio? Encoding = AMR (works)

  When I exit the capture I get supported types:

  Device supports capture Type: audio / amr
  Device supports capture Type: audio / basic
  Device supports capture Type: audio / x - gsm
  Device supports capture Type: image / jpeg

  To play, I think that I should put the x - wav player and provide good wav header, will try later, but my first concern registers directly as G711.

  I'm running on Simulator and device (BB Torch v6) which should be able to support the u-law/a-law.

  someone at - there more information on this? It is not possible or should I put the recorder in pcm mode and convert my data on the fly?

  Hi James!

  Registration is only linear PCM.  The reading can be linear, G711 uLaw and alaw for PCM.  On a BlackBerry audio/basic = audio/pcm.

  If you are interested, GSM is GSM6.10 of recording and playback, AMR's locker AMR - NB 12.2 Kb/s (unless you specify voipMode = true in your locator, but I will not go into these details, you can search the forums if you need more information on this) and any mode of AMR - NB valid for playback (only three units I know can also playback AMR - WB and AMR - WB +).

  Finally, to save some time there is code attached to this question (if you can connect, related to this thread) who has code to generate headers wav on the Blackberry platform for you.

  When I try to write ECM/pcm audio or audio/basic for Simulator ContentDescriptor throws MediaException.As I understand that I did something wrong, but how can I give a pcm for ContentDescriptor entry?

  Any ideas?

  ThanksMSohm , but I already find solution. For that Datasource accepts the pcm (it's weird), but you must write audio/x-pcm not ECM/pcm audio or audio/basic. Before that he was the exception in time of creating player.

• Custom player DataSource without possible RTSP streaming?

  Dear people,

  everyone SUCCEEDS with Manager.createPlayer (source of data source)
  with the data source customized with real audio STREAMING?
  I mean without using the "rtsp: / / ' locator, just feed the player with your data buffer, which is more...

  Example of the RIM is downloading the full file first is nothing new compared to the default behavior of the reader (read full datafile before playing; I understand that it could get in the J2ME standard, but then these methods makes no sense

  When I try to read an audio stream (audio/amr) I see that the Player tries to put first the cached data (called read() length from 58000 until my current buffer size), the computer begins to play (the role he was able to buffer at the beginning) but ends by with code 5 error what Unspecified «» : an error has occurred which does not fit into another category. »

  It looks like you are not conform to the contract of the SourceStream.read method. First of all, if currentPosition + len > stream.size (), and then you return stream.size () rather than the () - currentPosition bytes stream.size bytes. Second, if currentPosition + len<= stream.size(),="" you're="" returning="" the="" right="" bytes="" for="" the="" first="" time,="" but="" then="" you="" don't="" appear="" to="" be="" updating="" the="" currentposition="" variable="" --="" so,="" if="" the="" condition="" is="" still="" true="" on="" the="" next="" read,="" you're="" returning="" the="" same="" frames="" as="" last="" time="" causing="" the="" user="" to="" hear="" a="">

  Here is how the read method should look like (minus the part blocking when no data is available and less-1 or EOFException when the SourceStream is closed or stopped)-I have tried compiling or running it though:

  public int read(byte[] b, int off, int len) throws IOException {  if (len < 1) {    return 0;  }
  
    final int streamSize = stream.size();  final int currentPosition = (int) this.currentPosition;  final int bytesToReturn = Math.min(streamSize - currentPosition, len);  if (bytesToReturn < 1) {    // TODO: Need to block here on the stream until some bytes are available    return 0;  }
  
    System.arraycopy(stream.getByteArray(), currentPosition, b, off, bytesToReturn);  currentPosition += bytesToReturn;   return bytesToReturn;}
  

  PS Examples of RIM (do not remember those who) have a shared stream in which a son written data and another thread reads the data from. This may be another (simpler) solution to your problem, your reading will be a one-liner: return sharedStream.read (b, off, len).

• Is there a converter optional/codec for audio format '.amr?

  The. Audio format AMR used in my smartphone Blackberry does not seem to be recognized by Media Encoder CC.

  There are a plethora of free converters out there; but I question their legality & I'm afraid of potential viruses...
  I really wish that Media Encoder CC could pass for me in this regard...
  Assume, correctly, that Adobe does not want to pay fees for this codec?

  Hi dayoldy,

  I really wish that Media Encoder CC could pass for me in this regard...

  Assume, correctly, that Adobe does not want to pay fees for this codec?

  Sorry, only the following audio formats are supported: file formats supported first Pro CC

  Thank you

• Can I play a file AMR downloaded from my smart phone, on Windows media player and if so, how?

  I pulled a few files of playing me the guitar to my computer from my recorder App on my Smartphone Samsung Infuse, when I try to open the fles to hear a window says windows media player can't open files, would like to really hear these things, is there any way I can, thank you very much.

  Hello

  AMR files can be converted to MP3 or you can use the best codec.

  If 64 bits and you need codec.

  Read this 1st and go that route, or use the one below. (Vista or Windows 7)

  http://www.Vistax64.com/sound-audio/152850-Vista-codec-pack-32bit-64bit-Media-Player-codecs.html

  --------------------------------------------------------------------

  If 64-bit - can run WMP in 32 or 64 bit mode.

  Or try these: download - SAVE - go to the place where your put them RIGHT CLICK – RUN AS ADMIN.

  For 32-bit use these - OR the 32 bit ones listed above which I prefer.

  K - Lite Codec Pack 8.1.7. (or newer)
  http://www.codecguide.com/

  Use them for 64-bit:

  K - Lite Codec Pack 5.6.0 (64-bit) (or newer)
  http://www.codecguide.com/

  -------------------------------------------------------------

  You know that you use WMP 32 or 64

  Change, modify or value 64-bit Windows Media Player 11 (WMP11) in Windows Vista x 64 as default (or WMP12 - Windows7)
  http://www.mydigitallife.info/2007/01/19/switch-change-or-set-64-bit-Windows-Media-Player-11-WMP11-in-Windows-Vista-x64-as-default/
