    Acoustic echo cancellation

    oeann Community Member

      Hello, I develop in flash CS5.5 and I installed the player 10.3.

      I try to use AEC with the new microphone options but that does not work.
      Is this feature really works newly implement?

      There is there a solution so that the sound coming out of the speaker is not captured by the microphone?

      thank you

          there is one microphone method and one property you can use:  setUserEchoSuppression() and useEchoSuppression, resp.

            I use function like this:

            mic = Microphone.getEnhancedMicrophone();

            var options:MicrophoneEnhancedOptions = new MicrophoneEnhancedOptions();

            options.echoPath = 128;

            options.mode = MicrophoneEnhancedMode.FULL_DUPLEX;

            options.autoGain = false;

            options.nonLinearProcessing = true;

            mic.enhancedOptions = options;

            mic.rate = 44;

            mic.gain = 50;

            mic.setSilenceLevel(10);

            mic.setUseEchoSuppression(true);

            mic.setLoopBack(false);

             

            But this dont work. The speaker sound is captured by the microphone.
