Hi, in Windows 11 some sound cards have build in

Acoustic Echo Cancellation (AEC)


Acoustic Echo Cancellation (AEC) is a common audio effect implemented by Independent Hardware Vendors (IHVs) and Independent Software Vendors (ISVs) as an Audio Processing Object (APO) in the microphone capture pipeline. This effect is different from other effects typically implemented by IHVs and ISVs in that it requires 2 inputs – an audio stream from the microphone and an audio stream from a render device that acts as the reference signal.

This new set of interfaces allows an AEC APO to identify itself as such to the audio engine. Doing so results in the audio engine configuring the APO appropriately with multiple inputs and a single output.

Thanks, but this is about Echo, not about the cancellation of side voices :(

I think it works as you want, I tested, I hear my voice and no external noises and no echo of my own voice. I think you must try. it works better then Jabra from article.

The problem is not an echo or external noises, but the voice of another person, speaking 2-3 meters outside of you. Could you please ask someone to do this and check how loud their voice will be recorded, compared to your own? Thanks!

I tested, 2-3 meters voices have around -10 dB, it seems it's not a very good suppression

Thanks, but that optimized for speech mono sound in Jabra drives me crazy! :( And about JBL - which model did you try? Does in declare some kind of mic noise cancellation?
