Pitch Analysis

There have been delays in receiving most of the pitch data from this week for testing. One important recording, C Major Scale by one of our opera singers, was obtained and testing yielded ~97.83% accuracy. This task is a little behind, so I will be following up with the team to get access to more crucial tests, such as Happy Birthday.

CQ Analysis

Currently the program now extracts CQ values at timestamps that correspond to the time a given pitch is from. The next step will be to implement a way to choose a set of CQ data based on an identifier (such as the name of a repertoire or the key of a scale for “name-less” warm up recordings). The idea is have a system that allows the front end to pass in these identifiers and receive the clean sets of data to pass on to DPG for graphing.

I conducted interviews with the vocalists this week to gain a better understanding of what changes in CQ they would find helpful to know about. The main takeaway was that they would like help in identifying “flutters” and “wobbles”. I am currently working on understanding how a CQ measurement might indicate one of these problems. There do not appear to be research papers on this specific topic, but if we take CQ measurement recordings of these problematic samples and compare them with ideal samples, there may be a pattern we can discern.

Regarding the issue with collecting audio and EGG signals at the same time, I have proposed transferring ownership of the Voce Vista access key to my computer which has a USB-B port that may solve the issue. Unfortunately, this might mean limiting Tyler’s ability to collect data. For the time being, we have decided to focus on implementing the first upcoming task mentioned in this section so that the front-end has something tangible to demo for the vocalists.
