Week 10.4

Progress

So we had this problem of getting flow designer to work because it updated inbetween us meeting. We tried the replacement program, but it was buggy and didn't meet our needs, so we had to revert back to the previous version of flow designer with the current version of the packages we need to run.

We completed the first tutorial of using flowdesigner, hark, and ROS. We published on a sample topic and were able to read the messages through ros.

Our problem now is with the fourth tutorial which actually does processing on a two channel wav file. The default response to an improper flow designer problem is a segfault which generally tells us nothing about what we did wrong in the process and is very frustrating and counterproductive to learning. Hopefully we find something soon to figure that out, but we're making progress considering the lack of appropriate resources we have.

We also read a paper and found a video on recognizing and localizing multiple speakers with an 8 microphone array. This seems replicable in our projects because each of the kinetics has 4 microphones.

Hopefully Hark's learning curve will level out pretty soon....
