Ses Teorisi 3

1)

Fundamental Frequency : Lowest Frequency of a complex waveform. It makes the pitch
Overtones : Higher frequencies. (upperpartials)
Harmonics: If overtones are multiple of the fundamental frequency (x2,x3,x4), so they are harmonics.
Noise : No harmonics.
Additive : İki waveformu toplama
Subtractive: Waveform dan frekans çıkarma
Frequency Modulation (FM)
Physical Modelling ( PM or PHM ) : waveformun fizigine giriyorsun sound create ederken.
PCM ( Pulse Code Modulation ) : Short Attack Sampled Waveforms

2) Analog Synth : Subtractive

OSCILLATOR -> EG -> FILTER -> AMPLIFIER

3) Oscillator : Bir frekansta periyodik waveform uretir.
(VCO : voltage controlled oscillator)
(DCO : digitally controlled oscillator )

4) Low Frequency Oscillator ( LFO ) : Modulation Generator da denir.
10Hz in alti ile çalışır. Yani Kulağın duyabileceği
( kulak 20 Hz ve ustunu duyuyor )

5) Pulse Width Modulation ( PWM) : Dalga dongusunun genişliği ile oynama
