This week I prepared for our demo. We will be able to show cross-similarity matrices between various songs and some samples, and have some evaluation present for tuning chroma features to provide clearer and more distinct patterns in the cross-similarity matrices. Hopefully, some heuristic evaluations of the similarity will show some trends that could allow us to pick a song out based on a sung sample. Failing this, we can look at a classifier that can determine the difference between a match and a mismatch from sung sample-> actual song waveform.
