Chapter I: Subtractive Analog Synthesis


Analog synthesizers use analog circuitry to create electronic audio signals.  These electronic audio signals are converted into sound by a speaker using an electroacoustic transducer.  There are five main sections of a signal path in a basic subtractive analog synthesizer:

1. Oscillator (VCO)
2. Filter (VCF)
3. Amplifier (VCA)
4. Low Frequency Oscillator (LFO)
5. Envelop Generator (EG/ADSR)

Many of these synthesizer principles form the basis for the synthesizer technologies in the coming chapters.
