Flex :: Acoustic Echo Cancellation In Flash Using Native Libraries

Feb 4, 2010

I have to implement AEC in Flex video conferencing application. I know that it can not be done directly in Flash. I'm thinking to write a native application or library that will do AEC outside Flex.

As far I know Adobe Connect Pro is using some external library that do AEC. I'd like to follow this direction and do something similiar.

There comes two possibilities in my mind:

1) Independend custom AEC filter.

The custom AEC filter will be run in the background and will be processing all data from microphone and sound card and doing AEC. The echo signal will be the data that is to be played but delayed in a temporary buffer, something like this: aec(input, delayed_input, output).

I don't know if it work, because Flash microphone input doesn't know about my custom input and the same with the speakers. But how it is done in WinXP/Vista that have AEC at the system level?

2) AEC filter interacting with Flex's NativeProcess.

The filter will be run by NativeProcess. Flex app will pass microphone sound, received remote voice to the filter and return voice with echo removed and then Flex will output this to the speakers. Will it be correct?

If the 2) method is OK then I have following questions:

I will start with Speex's AEC so in what format should be the data pased from Flex? If I choose Flex Speex codec for sound compression can I pass it directly to the speex library? Will be the performance OK? Calling NativeProcess library every sound frame buffer can be time consuming I think. Why there is no AEC implementation in AS3 that can be used directly from Flash? As far I know to do AEC you must have echo data and microphone data (in Flash 10 there is direct access to the microphone). There is definetly something that is stopping doing it like this but I don't know what it is yet :) Is there some free AEC implementation or a DSP library with in except Speex's that I can use?

Actionscript 3 :: GetEnhancedMicrophone Method For Echo Cancellation In 10.3 Bugged?

Sep 20, 2011

My code:

mic = Microphone.getEnhancedMicrophone();
var options:MicrophoneEnhancedOptions = new MicrophoneEnhancedOptions();
options.mode = MicrophoneEnhancedMode.FULL_DUPLEX;
options.autoGain = false;
options.echoPath = 256;

[Code]...

In my application I am indeed using the enhanced mic, but echo cancellation still persists.

I think this is a bug Adobe needs to fix, am I the only one having this issue?

Flex :: How To Edit Item In DataProvider With Support For Cancellation

Jul 9, 2009

I have a DataGrid of objects, and I want to modally edit them; pop up a dialog, change the item, and if the user clicks "Ok", save the changes back to the original item, and if they click "Cancel", do nothing. It seems obvious that if I simply pass in a reference to the original object and change it using data bindings to the fields in the edit form, I won't be able to cancel my edits. How can I support that capability?

ActionScript 2.0 :: PHP Echo Back To Flash?

Nov 8, 2004

I am trying to do a simple php echo to flash. I want to do a loadvars.load("tomyscript.php",0,"POST"); and echo back an address....such as echo "[URL].. in php and I want flash to be able to read it. I have sound very little on echo back to flash, maybe I am typing the wrong keywords. I have done this before, but this was my code:

PHP Code:
<?php     $returnvar=$testvar;     echo("returnvar=".$returnvar); ?>

I am not sure why that works and my other echo doesnt.I tried using that script for my idea too and it didnt work. If someone can clear this up for me that would be great, so I can understand why it's not working and what it's doing.

ActionScript 3.0 :: Sound Echo In Chrome?

Nov 18, 2010

Has anyone experienced an echo when using Google Chrome? It seems to only happen if the sound begins playing while other assets are loading, and while that may seem like an easy fix I want the sound playing during the loading sequence. I've tested playing the sound on a key stroke after all of the other assets have loaded and it does not play twice. This behaviour does not occur in Firefox.

I'm working on a project that requires me to communicate with a database. I am using PHP and mySQL with flash on the front end. My problem is that in order get variables back from PHP I have to double them or atleast double the first 2. So this doesn't work:
$loginResult .= " " ;
$loginResult .= "wasSuccessful=" . $wasSuccesful . "&" ;
echo $loginResult ;

But this does:
$loginResult .= " " ;

$loginResult .= "wasSuccessful=" . $wasSuccesful . "&" ;
echo $loginResult ;
And I only get one result.

Audio - Live Video Mic Echo When Using Apple Cinema Display

Dec 15, 2011

I'm using Flash Media Server to create a 1:1 video chat. The problem I'm having is that when I use my apple cinema display I get horrible Echoing, even with the reduce echo box checked. If I don't use my cinema everything works fine with the built in macbook mic. I have to believe there is a setting as I can use iChat, Adobe Connect, WebEx, Skype all with my apple cinema and not have this MIC echoing issue.

Our Current Settings:
Audio
var options:MicrophoneEnhancedOptions = new MicrophoneEnhancedOptions();
options.mode = MicrophoneEnhancedMode.FULL_DUPLEX;
options.echoPath = 256;
options.nonLinearProcessing = true;
