4.1 SYNTHESIZER BLOCK DIAGRAM ![]() The diagram above shows the different AXS synthesizer components and how they interact. The process of creating sound begins at the two oscillators called OSC1 and OSC2. These components create basic audio signals at audible frequencies (100-18000 Hz). The pitch of the oscillators can be individually modified by the pitch envelope. The signals created by OSC1 and OSC2 are then passed to the MIX component. In this component the two signals can be combined in several ways. The output of the MIX component is fed in to the filter. A filter removes or enhances certain frequencies in the audio signal. The filter cutoff frequency can be modified by the filter envelope. Next the signals volume is shaped by the amplitude envelope. The amplitude component also features a distortion effect. Finally the signal is sent to the effect section to add stereo delay or reverb effects which add spaceousness to the sound. |
