Presentation Transcript

  1. 千人交響樂 Yiju Lin

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

  3. Method • Get the Harmonics Part • Get the filter coefficients • Set the filters with different coefficients of timbre, pitch ,and amplitude • Than get the result • Get the residual part • Add the harmonics and the residual part

  4. Harmonics Part – 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

  5. Residual ( Noise ) part - IFFT • Use noise level to estimate the noise • Synthesized with original phase or random phase. (Just use “ifft”.)
