Personal Task Updates

• DONE Draft code for pitch analysis
• DOING Propose modification to Pitch Analysis Testing
• DOING Add normalization support to pitch analysis of vibrato
• DOING Draft code for streamlining Voce Vista

Pitch analysis is slightly behind, but very close to being done. Other that that, tasks are on-time. It is important to note that the task “Match Microphone Data to EGG” was marked complete ahead of schedule because Voce Vista already outputs the data we need for matching up time and pitch long-term, but only outputs CQ data in the short-term.

Pitch Analysis

Tyler and I collected some recordings of one of the vocalists singing scales and “Happy Birthday” in different styles (vibrato, staccato, with piano, without piano). Shortly after this, almost the whole team was feeling under the weather, so there has been some delays in getting this data uploaded to the drive. As soon as I have access to the new data, I will be able to implement the last part of pitch analysis, support for vibrato.  Prof. Sullivan and I believe that if I normalize the data appropriately, I will be able to extract the fundamental frequency around which the pitch varies when a vocalist is singing vibrato. Supporting vibrato would be great for making our product useful for opera singers, who we observed to sing vibrato naturally. Even when asked to sing staccato, occasional slips into vibrato occurred, so it would be in the interest of minimizing over-self-consciousness that we provide support for vibrato in our pitch detection. My goal is to have this support complete by the next status report. A modification to pitch analysis testing was also proposed to involve the vocalists and vocal coach as described in the previous status report, “our testing would likely be modified to include having a vocalist sing a series of notes, such as “Happy Birthday” and have the vocal coach verify that that the pitch detected agrees with their perception of the pitch for 90% of the notes sung.” This proposal is awaiting feedback.

Match Microphone Data to EGG

As stated above, this task is being marked as complete and the team is instead focusing on actually extracting and exporting CQ data long-term in the same format as time and pitches. Tyler and I are working together on this, but he is taking the lead on communicating with Voce Vista support for learning how to export this data as part of his task “Integrate EGG Data”. If there is further support needed to match CQ to time stamps, this tasks would reopen.

Streamlining Voce Vista

Adding any support to streamline the use of Voce Vista would be in the interest of our product to make the analysis process easy for our users. Voce Vista does not appear to support the command line, but it has an extensive list of configurable keyboard shortcuts. These shortcuts could be conditionally triggered from a python script with the keyboard library. This week, I will add code with functions to trigger Voce Vista functionalities including opening the app and immediately recording upon startup, stopping a recording, and exporting time and pitch data to a specific folder in the repository.
