This week, our main focus has been on trying to track down our EGG sensor. We got in touch with Professor Leah Helou at the University of Pittsburgh, but were unable to actually pick up the sensor. A new pickup date has been rescheduled for early this upcoming week.
We also did further research into reading about the laryngeal closed quotient, getting more clarity on how our app ought to measure CQ and give feedback. There was also some important methodology concerns that were further discussed through readings, such as getting a proper CQ measured from sung notes that vary in frequency.
We worked on making decisions about and setting up our technical stack. We’ve decided to use a Python backend due to the accessibility of signal-processing libraries like Librosa and music21. For the frontend, we will tentatively be using TKinter for our GUI. See a more detailed schedule for the frontend development in Susanna’s update post (specifically with regards to the recording and replay pages).
On the signals processing side of things, we were hoping to use VoceVista to process the EGG signal. However, this is an expensive application, and we’re not sure if it’ll be possible for us to get a free trial to test it out.
