When will flash have acoustic Echo cancellation?

Do you know if this will be in the next version? are their any short term solutions? I have a live video site and the audio is screaming and there are echo's without use of earphones. Please advise!

This probably isn't the answer you are looking for (and I haven't done any micropohone use with Flash before), but I do know from my audio recording experience that live audio + hearing that audio through your own speakers (which gets back to your mic) can create a feedback loop. Headphones are the only true way to deal with this (and eliminate the feedback). On this level, it has nothing to do with Flash.
Is this qhat you're asking, or something more specific to what you can actually program with AS3?
If your issue is with recording audio using Flash, have you gotten familair with the Microphone class (flash.media.Microphone)?

  • When will Flash Builder 5 be released?

    When will Flash Builder 5 be released?

    Good idea, i want work on Flash Builder 5
    PS: Suggestion for mossed components since 2004 by Macromedia Inc.
    Very old components from Flash MX 2004 / Flash 8 we missed there.
    Flex SDK sees **** because xml-list for menu and it sometimes get error like menu doesn't load xml.
    I knew about good functions by menu components from MX 2004 / 8 like thios
    <instance> is menu component:
    package
      // Convert from old component by Macromedia into AS3
      import components.Menu;
      import components.MenuItem; // Idea by SourceSkyBoxer
      import flash.Display.Sprite;
      import flash.events.MouseEvent;
      public class MainApp extends Sprite
      private var menu:Menu;
      private var fileItem:MenuItem;
      private var closeItem:MenuItem;
      public function MainApp()
      menu = new Menu();
      menu.addItem(fileItem);
      menu.x = menu.y = 10;
      this.addChild(menu);
      fileItem = new MenuItem();
      fileItem.label = "File";
      newItem.addItem(closeItem)
      closeItem = new MenuItem();
      closeItem.label = "Close an application!";
      closeItem.addEventListener(MouseEvent.CLICK, onClickCLose);
      private function onClickCLose(mev:MouseEvent):void
      // Something function for handler
    PS: I really missed Menu Component because MouseEvent.RightCLick / MouseEvent.CONTEXT_MENU are available since Flash Player 9. I am getting crazy because Menu Component from Flash Pro 9, 10, 11 and 12 haven't yet. Now Flex SDK has MouseEvent.CONTEXT_MENU here and i have tested Menu from Flex Component ( Flex SDK 3.6.0a ) = It works fine like i have created example desktop into Flash Player 11
    Build by Flex SDK 4.9.11 with MX Version.
    But i want go back Flash Pro CS5.5 / Flash Pro CS6. - Did you develop any minimal components for Pure AS3?
    And i have tested with Aspiere Component uiMenu and it works fine, too with Away 3D under Flash Builder 4.5
    PS: Aspire Components has faked skins like Windows 2k, XP and Vista Skins
    There images are Flash Player 12, Aspire Component UI by Ghostwire with Away3D 4.1.6
    But Aspire Component sees like Flex Components But they won't work with Away 3D - View3D inside uiWindow was hidden.
    For future with Flash Player 13/14 looks like accessed hidden contextmenu like Qooxdoo Frameworks. I want to hide with Flash Player's Contextmenu.
    Application's Container should to set to false without contextmenu. = No contextmenu? If they like this.... Thanks for support

  • When Will flash be available on the iPad ?

    Incorrect, Wallaby does not convert Flash applets to html5.
    What Wallaby does is allow you to use ONE tool in flash, the timeline, which is used to draw and animate. Nothing else flash does can be exported using wallaby, only timeline animations.
    Basically what wallaby does is allows you to make an html5 equivilent of an animated .gif
    ZERO code used in flash is exported, meaning zero interactivity can be exported.
    Not only does wallaby only export timeline animation in animated gif format for use in html5, but it cant even export filters, like glows, drop shadows etc.
    Wallaby simply takes advantage of a new animation element just released on the web called <canvas> it uses canvas to show your animation, exactly like a gif. No interactivity, no code, nothing, simply a stationary animation.
    What you do with that animation beyond wallaby is up to you, just like developers have been using animated gif advertisements, wallaby is ment to do the exact same thing, allow advertisers who have simple animation banner ads, publish them to html5 format for use on ios.
    Yes that is right... no longer do you have the ability to block ads on ios like you can on all other systems, because your ads very soon will be in a format that you or your computer can not distinguish between actual needed content.
    Again, wallaby simply makes html5 versions of animated gifs you build on the timeline, that is all it does, it makes animated gifs.

  • Acoustic echo cancelation in FLME

    Hello
    I read a paper http://www.adobe.com/devnet/flashplayer/articles/acoustic-echo-cancellation.html about echo cancelation. Now I know how to use enchanced microphone. But it's only setting for output microphone in client. What to do if echo received from Flash Live Media Encoder?
    Is it some API solution for client? Or similar setting in FLME configuration?

    'Silencer' function of PCIE Titanium X-Fis works only with Creative proprietary mics&headsets, so is nothing to transfer.

  • When will Apple have a searchable text reader and upload file capability?

    When will Apple have a searchable text reader and upload file capability? I have a large text file I need to upload to my iPhone, search, and dial.
    Anything planned?

    I had a Palm the I used for work and travel it had a very nice application called DOCUMENTS TO GO. It allowed you to upload, view, and edit .doc, .xls, and .ppt files. this was very handy when traveling. Also, I could sync my palm with my iMac and work PC using bluetooth, took care of the file transfers as well. I would like to have the same capability on my iPhone. I bought it to replace all of my old stuff i need it to the same as my old stuff. I hope that Apple reads this and gets on the ball. Until then I still have to carry my Palm or thumb drive on trips.

    Me TV is most often a sub-channel (secondary or tertiary channel) from local broadcast TV stations that may or may not elect to offer them over the air and-or offer them to Comcast to have available on cable.
    There is not currently a broadcast station in your area that offers Me TV.

  • When will flash builder support export to Windows Mobile OS?

    When will flash builder support export to Windows Mobile OS?

    I think maybe VB was confused by you calling it "Windows Mobile," as Windows Mobile is MS's obsolete, abandoned Mobile OS for pre-iPhone era with a stylus and all that, I am assuming you probably meant "Windows Phone" / Windows 8 Metro UI / Windows RT, the new iPhone-like MS Mobile OS.

  • When will iTunes have a Ukraine store?

    When will iTunes have a Ukraine store?

    The following must be said in relation to this discussion ...
    Ukraine is a modern European country of more than 45 million people.  Ukraine is an independent state with its own unique language and culture.  Since breaking free from the evil Soviet Union, Ukrainian society has taken major steps to rid itself of the stagnant Soviet model which included Russified linguistic, cultural, economic, social, media, and political tendencies. Ukrainians should not have to depend on Apple in Russia or Poland, or any other neighbouring country to fully enjoy Apple products.
    Apple Inc. can start by fully enabling APPLE.UA as the official site for Apple in Ukraine - oh, and please make sure the website is presented in the official language of Ukraine - UKRAINIAN !!!

  • When will we  have IOS6.0 for IPDA one?

    When will we  have IOS6.0 for IPDA one?

    Apple stopped selling the iPad 1 two and a half years ago.  Your iPad 1 can still do all the things it could do back then.  It is not capable of running iOS 6 since it does not have some of the chips in that iOS 6 requires.  There's nothing anyone can do about it.  If you find this unacceptable, please contact Apple.  There's no point posting about it here: nobody from Apple has any responsibility for reading these groups.  We are just users of Apple devices helping each-other solve technical problems.
    If your needs have changed in the last 2.5 years, then you will have to buy a new device.  If your needs are still the same as they were 2.5 years ago, then your iPad should still be doing the same things it did back then.
    I trust that this answers the question you have about your iPad.  If you need help with a technical on a different subject but still related to "iPad in Business and Education", please do not hesitate to post it.
