Hi,I am interested in this project, (I use jack as input but with an array with 6 mics ,and I choose three of them as a triangle array)
however,when I run roslaunch soundloc soundloc.launch,terminal show like this :it just show a plot with 1-360 degree,it does not return the direction of voice.

how should I fix this problem?

Could you give directions on how to setup the environment to compile your project on a Linux system?
