1. 千人交響樂 Yiju Lin Advisor : Alvin Su

2. Outline The Signals of Music Method Flowchart LPC synthesis Synthesis Handling problem Demo Future work

3. The Signals of Music Harmonics part – Ex : C1, D1, … Residual ( Noise ) part

4. Method Get the filter coefficients Set the filters with different coefficients of timbre, pitch,and amplitude Than get the result

5. Flowchart Score only Violin I Violin II Viola Cello Violin I -1 Violin I -250 Violin I -…

6. LPC synthesis True envelope estimation TE- LPC 得到 filter 的參數 Coefficients 只是找形狀 Impulse Train * LPC Filter = Harmonics Part

7. Synthesis True envelope coefficients System Result Part of result & Setting

8. Handling problem Make the database to save the coefficients of different pitches Dealing a note at a time(synthesis) Dealing the different violins at a time(only 4..) A bar a wav Volume of a note Length of a note

9. Demo Original Systhesis(bar 1) (bar 2) – And random change the volume of the notes

10. Future work Use MPI(for windows) to get the result of other instrument Make a better score reader More expression More like the real Real time
