So far, everything is going according to plan and no major risks are present with regard to our project’s progress. As Jose’s interfacing baseline is setup, the major risk of having no button/key/tactile feedback with our system has been resolved (the video showing this is shown in Jose’s report for the week). As talked about in the interim report, the schedule has been updated to represent the work we’ll be doing on the actual overall physical interface. Since we want to make a box storing all the components and the like, time will need to be invested in designing and printing/laser cutting. Here is the updated schedule for such:
Our plan for testing the whole system initially involves playing different audio wave types/drums in combination with filters, checking that the audio corresponds to the intended filters/waves chosen. Note frequencies will be tested by using a spectrum analyzer app, making sure that the MIDI key played is accurate to the one outputted. End-to-end latency (where we’re targeting < 10ms) will be tested through an Audacity two channel recording. The first channel will be connected through the MIDI keyboard (where we can have it connected to a USB apart from the MIDI DIN) while the second is connected to the output port of the FPGA. Signal quality/aliasing will be tested, as previously discussed, through Matlab. We’re going to record the output coming out from the FPGA through the 3.5mm cable and then import it into Matlab to compare with an ideal signal.
