Hey,
I would like to use this package for XMOS 7 array Microphone. But, when I launched das.launch
, I got some error, so I did jack_control start
(to start jack server) and usermod -a -G audio <theusername>
(to avoid cannot allocate memory: permission denied)
Now, I get:
... logging to /home/ajay/.ros/log/1332ee66-4f2f-11ea-990f-708bcda03968/roslaunch-ajay-5744.log
Checking log directory for disk usage. This may take awhile.
Press Ctrl-C to interrupt
Done checking log file disk usage. Usage is <1GB.

I wonder is there any tutorial for this package? Because, I'm not sure on how to interface with the proper mic and to verify if its working.The beamform node seems to run even when i disconnect the mic. I think, it has not selected the appropriate mic. How to do it ? and what does auto_connect: false
do? and what does d
and a
means in Mic #0, Mic #1, etc.. ?
Finally, Is there anyway to get the raw audio data from each of the channels separately?
