Assignment 3

 

Part 1 (Due Tuesday February 14 at noon)

Read the following article:
Bello, J. P., et al. (2005). “A tutorial on onset detection in music signals.” IEEE TRANSACTIONS ON SPEECH AND AUDIO 13(5): 1035–1047.

Briefly answer the following questions:
1) What is the difference between an attack and an onset?
2) Why is preprocessing is typically done to the signal?
3) What is the purpose of reduction?
4) What is the role of peak picking?

 

Part 2 (Due Thursday February 16 at noon)

Create a function to reproduce the following plot using YIN and the CorrelogramPitch function in the Auditory Toolbox (both directly from the signal and using the cochlear model from LyonPassiveEar). The function should take a filename (in this case avmA.wav) and an optional structure with the following (optional) fields: minF0 and maxF0 (for YIN) and width and frameRate (for the Auditory toolbox functions). For the purposes of these specific plots, minF0 should be 220, maxF0 should be 880, width should be 256 and frameRate should be 50. Make sure that your function supplies default values if the optional structure (or one of this fields) is not passed in.
