The Signals of Music Harmonics part Residual ( Noise ) part Ex : C1, D1, … Residual ( Noise ) part
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
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
Residual ( Noise ) part - IFFT Use noise level to estimate the noise Synthesized with original phase or random phase. (Just use “ifft”.)
