• You can only amplify the noise above a certain threshold?

  I am trying to raise the floor of a topic that I interviewed in a video clip at an event where people are wandering around in the background. A simple amplification could raise his speech, but also the level of background noise. Is there a way to amplify a few servings of a signal that cross above a certain level (by example, - 12dB) and let alone all the other elements of the signal?

  A filter compressor seems to do the reverse, bringing spikes in the rear volume in relation to the volume of all the rest. I want to emphasize the stronger parts while minimizing background noise.

  Well, I won't be quite as inactive on the idea that my other two friends (and they'll probably be right and me wrong), but...

  It depends on how much improvement you want to put up with on the treatment plan.

  If you configure the effects/Amplitude effect and treatment of the Compression/dynamic a little bit like that, it will indeed start amplify all signals above - 12 (roll out slightly below 0) without touching the stuff below - 12.  If you want to be really drastic, you could add another point to the line and do the things under - 12 are slightly reduced.

  

  However, you will be using a set up as this can easily make the pump sound a bit and you may not like the sound.   I always suggest experimenting until you get the best combination of usable sound quality and an acceptable level of process objects.

  Hi, Kent,

  If you want to know who has 3 rows within a period of 1 hour. right?

  The query you posted can be simplified:

  WITH     got_prev_logtime     AS
  (
       SELECT     username
       ,     logtime
       ,     LAG (logtime, 2) OVER ( PARTITION BY  username
                                           ORDER BY      logtime
                            )           AS prev_logtime
       FROM    log_table
  )
  SELECT DISTINCT       username
  FROM   got_prev_logtime
  WHERE  logtime     <= prev_logtime + (1 / 24);
  

  In your original request, max_group_logtime was just the logtime since the current line.
  You have been calculated for groups of up to 3 lines, and then calculating the min_group_logtime and finally to test to see if the Group contained really 3 rows.
  LAG (logtime, 2) combines these steps. Returns NULL if there is not at least 2 previous lines and otherwise the logtime of the older.

  Thanks for posting the sample data in a useable form. It is a big help.

• How to get the length of a waveform above a certain threshold?

  A simple problem... I have acquire the data of the DAQ Assistant and read it back draw the measures file using read.

  My signal will be with just a peak (see figure)

  I need to find the duration for which my wave form value is more than 150.

  I am unable to find that the waveform of time first crosses threshold... but the second point waveform the threshold comes in... I'm not able to find

  second attachment is part of the created vi...

  If I can find the second time where the wave goes the threshold, I can calculate the time using dt...

  As David and VSH have hinted at, you can use threshold spikes.  I did it several times...  See the attached VI.

  Hello Jorstar1,

  Thank you for your message.  Windows Media Player 11 supports .avi, but compression can dictate whether he will play or not.  This is very probably a Codec issue, you can perform a websearch for a Codec that will play any avi compression.
  Please let us know if it did or did not help to resolve this problem.

• Portable speakers won't play all sounds

  I have a Dell Inspiron 1420, and somehow the built-in Laptop speakers won't play any sound at all, even when Windows starts. I run on a Windows Vista.

  In any case, I tried to go to Device Manager to uninstall my sound thing called "High definition Audio Device", but this still does not work. Then I tried updating the driver, still not working.

  The audio works when I plug headphones to one of the thing taken, but only on one, I have two of these good output jacks.

  Can someone guide me please how I can solve this problem? Thank you.

  Try to run the Dell Diagnostics audio tests. These interactive audio tests are designed to limit the problem software or hardware. The tests are independent of Windows and drivers, meaning that it is not serious if those who are working properly or not. To run Dell Diagnostics

  1 restart the computer and press the f12 key as soon as it begins to initialize.
  2. Select 'Diagnostic' in the start menu. The computer will run its evaluation of pre-boot (PSA) tests before the start of the Dell Diagnostics. In the PSA, you will hear some tones in the speaker system but it does not adequately test the audio hardware. Dell Diagnostics plays an instrumental piece of music complete with battery, so if you hear only a few tones then you have run only the PSA.
  3 Dell Diagnostics should open after the PSA tests, or you should see an option to open it. If you've never reformatted your entire hard drive then Dell Diagnostics will be gone as an option. In this case run it from the CD Drivers and Utilities (resource) If you have a.
  4. Select 'Custom', then the audio tests. (At this point - after you open Dell Diagnostic custom - if you can't find the option to select the audio test is a symptom of an audio chip faulty.)
  5. the tests will run. Alternatively using headphones and listen to the speakers in case a signal path works.
  The tests will play some audio and ask you if you heard.
  6 If you do not hear the music during the test, it certainly means that there is somewhere a hardware failure in the system. In this case Dell will repair the computer if it is still under warranty.
  7. If you hear the audio during the test, but not when you start in Windows, that almost always means the material is correct, but there is a problem with the audio driver or Windows.
  8. error codes: If you answer "no" to any question that the test ask, test generates an error code which can indicate a Dell technician that you answered 'no' to this question. The test does not know the exact component that went wrong. Before you answer "no" to a question, take note of the circumstances at that time here so that you know in general what is the error code.

  *****************************************************************************************************

  If the terst passes then try reinstalling the Sigmatel HD audio driver. You can find it in the Audio category of 1420 downloads page. I suggest that for best results you do not use the Dell Download Manager, simply download the normal way you would be using your browser.

  *********************************************************************************************************

  If the problem persists after installing the driver, you might have a problem with one of the headphone jacks when a computer has this combination of symptoms:

  * Speakers do not work and are not active or deselected
  * Headphone Jack works
  * Reinstall audio driver does not help
  * Audio test Dell Diagnostics passes
  * On models with 2 headphone jacks, you can be "verified" in the dashboard as if in use

  Laptops from Dell with 92HD audio using universal sockets of IDT, which is a bit complicated. In addition to the usual mechanical parts, making also uses current technology & detection of impedance to software configuration of trigger and switching (to send the audio signal to the speakers). There are three areas of potential failure: mechanical, electronic and software. Sometimes a little gentle wiggle of a plug in the plug will get to resume normal operation, at least temporarily. There is a safety edge stem into the socket (pin Sense_A) that is used to detect the presence of plugs, and it may be the cause of the failure to trigger the ignition of the software. Failure of the sense pin usually results in the computer behaves as if there is always a plug into the socket.

  Normally the audio test of Dell Diagnostics would confirm that there is a hardware problem, but universal Sockets can cause a false result Diagnostics. This is because diagnoses running BACK, outside of Windows, so a software configuration problem Windows is not relevant to test even if in this case it is caused by the material. If the audio test can spend in Diagnostics, signaling correctly that the configuration of the software is the immediate cause of the problem, but it lacks a hardware, the Jack or safety edge Rod problem, what the root cause. In these cases the reliable diagnostic procedures are only to try a new motherboard or use PC Restore (called Factory Image Restore in Vista) to restore the computer to its original as in factory configuration. If the speakers do not always work after PC/Factory Image Restore, then it is definitely a hardware issue even if it passes the audio test Dell Diagnostics normally infallible.

• How to play a sound file before you exit an application?

  Hey guys, I'm a newbie.

  I need dev an app it will play a sound file(mp3 perhaps) before release the app that my code is as follows:

  playAudio();       UiApplication.getUiApplication().invokeLater(new Runnable() {
                  public void run() {
                      close();
                  }
              }, 500, false);
  
  -------------------------------------------------- ----------------
  
      private void playAudio() {
          // first we need to find the supported content types
          String types[] = Manager.getSupportedContentTypes(null);
          for (int cnt = types.length - 1; cnt >= 0; --cnt) {
              if (types[cnt].equals("audio/mpeg")) {
                  // this sample demonstrates playing an MP3 file that has been
                  // added as a resource to the project
                  try {
                      // retrieve the MP3 file
                      InputStream is = getClass().getResourceAsStream(
                              "/sound/sound.mp3");
                      // create an instance of the player from the InputStream
                      Player player = javax.microedition.media.Manager
                              .createPlayer(is, "audio/mpeg");
                      // player.addPlayerListener(this);
                      player.realize();
                      player.prefetch();
  
                      VolumeControl volumeControl = (VolumeControl) player

      }
  

  the above code works fine on the Simulator, but not bad in real device (bb 9550). It closed just the app without playing the audio file. does anyone have a better solution?

  (Note: the mp3 file is very short, less than 0.5 s)

  first of all, I suggest you not to use invokelater like that, it's mainly to put things in the event queue and a system.exit does not queue. You can use a thread or a timer.

  Second, I guess that 500 ms is not enough time for your system to play audio properly. I also suggest to put the audio player in an own thread.

• Play a sound to a page with MP3s

  Hi all

  I have problems with playback of MP3s from a Web page. I'm working on a Web page showing the names indigenous nyungar for items and a link to an audio file for the pronunciation of the word.

  I have the following choices:

  1. download as a media - streaming mp3 download

  Disadvantage is that a new Web page to read the article, and I want the user to hear the audio file and stay on the web page. I got to chat and they said that the downloading of media requires its own Web page to play, so you can only choose to open in target _blank or replace the current Web page. This is not a good user experience for my client.

  2 embed the audio file with this code:

  < embed height = "50" width = "100" src = "soundfile.mp3" >

  < object height = "50" width = "100" data = "soundfile.mp3" > < / object >

  Downside, reads the audio file as soon as the page loads and I want the user to click the sound file to play when they choose to hear it.

  3 HTML 5 code as follows:

  < audio controls = "orders" >

  < src = "source Song1.ogg" type = "audio/ogg" / > "

  < src = "source Song1.mp3" type = "audio/mp3" / > "

  Your browser does not support the audio tag.

  < / audio >

  Will play a sound at the same time, but has a large image of a sound control panel. I also download each mp3 AND Ogg format audio file, such as Firefox reads only the ogg files using this code HTML5.

  I also found jplayer but it is HTML5 as well and also need the mp3 and ogg files.

  If anyone has any other suggestions to play sounds from Web pages?

  Thank you very much

  Mary

  Hi Mary, the good news on playback of mp3s with SoundManager 2 is that you don't need all the audio formats as you would if you just use HTML5 audio.

  SoundManager can tell if your browser does not support the mp3 (like Firefox) and will substitute for a Flash Player to play the file in these browsers.  If OGG conversion is not that attractive, then don't.

  Here is an article titled great by the developer of the SoundManager 2 on the oddities of the audio on the web: http://24ways.org/2010/the-state-of-html5-audio/

  I think that SoundManager 2 is the best way to get the most flexible mp3 player without having to convert audio files in ogg.  It is quite easy to make links to the MP3 files online players:

  1. Download SoundManager and unzip and publish your Site of BC (it's usually in a folder called "soundmanager2")
  2. Update your link (A) items to include the class "sm2_link" to the CSS file in the next step to apply styles to your link.
  3. If your links are linking directly to a .mp3 file, then you are done with the markup, but if you use the module of literature to view links mp3 then you need to add an extra class to your links called "inline-playable.
  4. Download this CSS stylesheet for your players online style and upload it to your site and reference it in the HEAD of your page or template in British Colombia.
  5. In the HEAD of your page or your model includes the script reference in the soundmanager file:
  6. Download this script creates the online players from your markup.  Reference this script after the reference soundmanager we created above in the HEAD of your page or model.
  7. If you want to try to work around a Flash blocker in case it uses a flash drive to play your audio file then just download and reference the CSS file in the HEAD of your doc as well.

  You should be all set after these steps. If all goes well a time or two, perhaps to everything you need to set up and test it.
