I am not sure why when AIR grabs the mic and the playback mode is voice it is not able to grab the native mic using the built-in echo suppression on the mobile - maybe it doesn't work because the playing audio is not the same "device" as the echo suppression is using to suppress the echo, or maybe some other reason? In any case, I could use the AEC. If anyone is trying to setup for voice/video calls, I have had success in the VOICE mode using a mic.gain = 50, and using a soundTransform.volume = 0.3, and setting the inbound netstream.soundTransform = to the soundTransform, and setting the SoundMixer.soundTransform = soundTransform after each change (MEDIA, VOICE, SPEAKERPHONE). This paper presents an acoustic echo canceler based on a U-Net convolutional neural network for single-talk and double-talk scenarios. When using eSpeakerphoneForVoice, it is much, much worse (as you would expect). This process is carried out with the help of echo suppressors and echo cancellers. As it stands today, when using VOICE with an audio or video call, if the user has the volume on the device set anywhere near maximum, the other end hears echo. Echo Cancellation is the process of removing echo from transmitted audio signals. In any case, I could certainly use this on mobiles when using dioPlaybackMode = AudioPlaybackMode.VOICE, or eSpeakerphoneForVoice. This function is useful for speech and telephony applications in. function to eliminate echo generated in the acoustic path between a speaker and a microphone. switching between enhanced microphone when sound output is Loudspeaker and to default microphone when sound output is headphones.

Get new features first Join Microsoft Insiders. The dsPIC DSC Acoustic Echo Cancellation (AEC) Library is fully compatible with G.167 standard for Acoustic Echo Cancellation. Acoustic Echo Cancellation on Android is now available with AIR latest beta build AIR 23.0.230. The most common AEC system requirements are: Adaptive filter length: 60 to 200 ms. Acoustic echo canceling (AEC) in VoP is used primarily within the IP phone implementation with handsfree operation.

I have been on the AEC issue for sometime, in another post. Note: These settings are audio hardware and software specific and may not be available for all microphones.
