I have seen similar topics in this forum but I see no final answer to them.
I have the Respeaker 4 mics array v2 and I would want to use it as a mic but while having music being reproduced near the mic, but from an external device, something like in the video https://youtu.be/XivM-6PRgX8
When I try the AEC from the tutorial of seeed it does not eliminate the music. I have the waveforms in the attached file, channel 0 is only a mix with higher amplitude of the four mics, without the preprocessing of the waves. I am currently running the latest firmware and see the waves with a raspberry pi.
Can the respeaker eliminate music sound (without lirics) and sounds from external sources as machines working or car engines? or can only reduce the noises reproduced by it and the video is only suitable for demo purposes.
