Advancements in LPC Synthesis for Violin: True Envelope Estimation and Future Directions

This document outlines the innovative methods of LPC synthesis applied to violin music, presenting a flowchart that covers harmonic analysis, filter coefficient determination, and resonance handling. By focusing on true envelope estimation, we show how to synthesize notes with various pitches and timbres effectively. The project also discusses the handling of individual notes, with a demo illustrating the synthesis process. Future work aims to enhance the synthesis system further by integrating MPI for diverse instruments and improving score reading capabilities for greater realism.

Presentation Transcript

  1. 千人交響樂 YijuLin 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 Violin I -1 Violin I Violin I -… Violin I -250 Violin II Score only Viola Cello

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

  7. Synthesis True envelope coefficients Result System 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
