If you want a beamfomer I have 1 here that I am doing for my project ears thing.
It will have to be gdrive as my phone died and locked out of github 2 factor auth until my new one arrives.
The beamformer works fine the argparser that I inherited haven’t totally worked out yet but its
./ds input_device=1 output_device=1
Run it and press enter to stop and it will list params and devices.
I will set up a github repo when my phones turns up.
Speed of sound is 343ms which with 48k input means a single sample = 7.145mm my custom mic is a stereo 95mm affair but dropping sample rate or smaller mic arrays will get less resolution and that is what the margin is as it just stop spurious errors guess really should have it set to 14 as 95/7 is max.
Its not really what I am going to use in project ears as it will be embedded into the code this is just an external one in C++ and my 1st bit of C++ hacking.
I just changed from file to a streaming alsa interface thanks to portaudio so thanks to
If you where going to use set the output to a loopback and then the other side will act as a mic source of the beamformed multichannel mic set as source.
Playing with ALSA loopback devices | Playing with Systems gives a decent guide but basicall whatever you play into a sink side becomes available as a source on the other.
So ramp up sample rate to max and use a plughw: to auto resample from loopback as then you will get resolution needed.
