If you think this sounds good, great! But let us prove it. One of our engineers recorded himself speaking over music being played. Hear for yourself how it really sounds with our full-duplex AEC demo below.
This is the raw data captured from the environment. There is no editing on this channel. Our engineer played some music from the device and spoke at the same time.Channel 1 Audio:
This is the music that the device was playing at the time.
