Here it is Purring Cat' sound synthesizer. (^__^)
Everyone easy can understand the schematic and how it works.
For me the sound is good enough and there are many possibilities
to do new presets.
But I will looking forward to your guys opinions, jokes and suggestions.
Something more about.
It is known that cat's purring sound is combination of harmonical resonances
with fundamental from 20 to 30 Hz and some noizy background (huffing, puffing, blowing etc.)
There is a realistic hypothesis that cats using such sound for self-healing in very general sense -
when they feel good and safety, purr helps to distribute "positive energy" all over the body
(and soul ???), especially to where there is problem, pain etc.
Most of people like this sound. Of course a real cat is the best source of sounds, love, health,
claws and egoism. But I've found that hearing this synth 5-10 min makes really feel better
so just try!
Sine bank produce resonances; filters make noise from pure white noise;
breath section contain periodical part (with AHDSR) and background noise.
The volume of each part slow random modulated (limits and freq are tunable).
The main section (purring core) have base (fundamental) freq knob,
mixer for all possible sound, reverb panel and breath freq section. Small Res gives
chaotic breath, max Res - almost periodical.
