I would like to use Respeaker core v2 as a 6-microphone array voice interface for an iOS voice recorder application, with the following audio processing algorithms: Direction of arrival, beamforming, noise suppression, echo cancellation, automatic gain control.
Preferably via Bluetooth, or 3.5mm
I activated the Respeaker as an external microphone using the following command line:
respeaker@v2:~$ pactl load-module module-loopback latency_msec=1 rate=16000 format=s16le
After having some troubles with the quality of the Bluetooth streams, I connected Respeaker to my iPhone through the 3.5 audio jack (using audio cable, Y mic-speaker splitter and a lighting-to-audio converter). This worked fine.
At the next step, I would like to activate the Respeakered beamforming and DOA algorithms in continues listening mode in order to separate the speaker’s voice from the environmental noises.
Is there a way to use the Respeaker core v2 as an external 6-mic-array?
I would appreciate any idea how to do that?
For your usage scenario, I think this product might be more suitable for you

Thanks,
Does the ReSpeaker USB Mic Array can be compatible with iOS devices using Lightning to USB Camera Adapter

Does its built-in audio jack can provide the microphone array output?
