Fairfield Circuitry Placeholder Bucket Brigade Reverb
Placeholder is an analogue implementation of a digital reverb algorithm using BBDs, mixers, VCAs and simple zesty filters. The topology in question is called Householder, allowing quick echo density even with only three delay-lines. There's no denying the power of algorithmic representation of our daily activities. But let's not forget that the complex-system underlying our lived experience, the background noise and uncertainty, is intrinsic.
Three independent analogue delay-lines act as foundation to this particular type of feedback-delay-network. A householder-reflection feedback matrix (figure 1) creates context for quick echo density; every delay line feeds back only to every other delay line. The excitation is looking for the longest way out. Surprisingly, this analogue implementation of a basic digital reverb algorithm sounds quite unique. Creating space that is both familiar and unusual.
Controls altogether allow for a surprising array of possibilities:
- large bingo halls
- bathrooms and shower stalls
- spring-like flavours
- semblance of plate reverbs
- unrealistically small rooms
- real close to flanging
