Investigation of the use of signal processing techniques in automatic music engraving Patrick Freer Honours Project Presentation

Today’s questions The Five Whats: 1.What is the Project? 2.What shall be Done? 3.What is a Fourier Transform? 4.What is the Time Frame? 5.What are Some Difficulties?

1. What is the Project Changing analog music to a digital representation Making use of the work done by John McGuiness

2. What shall be Done? Perform frequency analysis (Fourier Transform) Isolate harmonics & time signatures

3.1 What is a Fourier Tansform? Transforms time domain to frequency Every function can be built up with an infinite series of sin() and cos(). Shows what note was played, but not when.

3.2 What is a Fourier Tansform?

4. What is the Time Frame? Three phases: 1.Research and concept work 2.Initial implementation 3.Extension and testing

5. What are Some Difficulties? Feasibility Distinguishing between notes and harmonics The exchange of time and frequency resolution
