1. 千人交響樂

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

3. Method Get the Harmonics Part Get the residual 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”.)
