Acoustic Echo Cancellation with Adobe Air on mobile

Question

Does anybody achieved echo cancellation in mobile application built by Adobe Air?

There are:

• Microphone.getEnhancedMicrophone() but it returns null on mobile device.

• Microphone.setUseEchoSuppression(true) also doesn't work.

• Maybe with ANE? I saw echo suppression settings in Apple Docs

Anybody?

Answer 1

It is now implemented in the latest AIR SDKs (v22 and v23).

So you can now use Microphone.getEnhancedMicrophone().

And you will also need to add this permission for Android:

<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
