Ben’s Status Report 12/7

The initial part of the week was largely spent getting the final presentation in order (up through Sunday). Helping Mathias plan and practice.

Other progress includes getting two audio streams to work at the same time from two Scarlett Device inputs with some noise issues. The issue now is properly interleaving the stereo channels of the piano microphone input to ensure the levels are balanced and notes are being heard as accurately as possible.

As things wrap up, I am shifting focus towards the deliverables ahead including the final poster, video, and paper. Though I hope so still try and spend some time optimizing the system a bit more.

In reflection, the audio processing seems to mainly pick up only the lower notes of the piano when multiple are played at the same time. Knowing this we could have chosen a cardioid microphone, instead of the ORTF, to record the lower end of the piano with higher accuracy and less noise. Given more time I would have liked to include an active normalization for the audio so the processing was more consistent and we could choose (and know) the noise floor to better filter note detection. I also would have wanted a bit more robust method of demoing. As of now the system is not designed to pick out music from a noisy environment like the demo is set to be which will be a significant issue for getting any accurate live results.
