Abstract
This writing discusses the background, design, testing, and implementation of a fully analog audio signal processing chain. This chain consists of a 4-band equalizer, phaser, tremolo, clipper, and wah-wah, the order of which is permuatble by patch cabling. This chain is meant to serve as the post-processing for the \textit{Waveform.ai }project AI-powered synthesizer. Engineering and appropriate design for low-frequency oscillators and voltage-controlled resistors are discussed, as well as design of the above-mentioned processing effects. Lastly, the system-level integration of all circuits is explored. Analog signal processing was found to demonstrate exceptional capability accompanied by unique sonic characteristics which distiguish it from digital signal processing. Although many audio effects may be implemented practically in the analog domain, some others—especially time-based ones—are far more difficult and require specialized fabrication.
