## What is Spirangle?

Spirangle is a delay. It's actually two delays. The first delay is a three-tap delay. The second delay is a feedback delay. The three taps from the first delay are sent through three independent filters. The three filters are SVF filters with plenty of available resonance and drive. The filters can have stereo separation applied to them. The three taps are individually routed, pre-filter, to the feedback delay mix section. The feedback delay mix section also includes an input which is a sum of the three delay taps taken after the filters. The resulting mix is then sent through the feedback delay. The output of the feedback delay then goes into a stereo effect unit that does LFO driven panning, chopping, tremolo, and left-right ping-pong manipulation to the signal. The output of the effect unit is summed with the input signal and sent back into the cycle.
