(t>>(t>>(t>>12&15)))>>t
Some kind of Non-JS echo effect I discovered?
((t*(t>>12))<<(-t>>10&7))&-t>>2
Nice stepdown effects there
t*(t>>(t>>10&7)&t>>12)
Fuzzy!

Cool percussion track

t<<(t>>8)*231
Lord Graga's Frere Jacques made proper by multiplying that array
((t>>7|3*t|t>>(t>>15))+(t>>8&5))*[8,8,9,9,10,10,-8,-8,10,10,11,11,12,12,12,12,-12,13,12,11,10,10,-8,-8,8,8,6,6,-8,-8,-8,-8][t>>11&7|t>>12&24]

Stimmer but the patters are inverted
t*(4|t>>13&3)>>(t>>11&1)&128|t*(t>>11&t>>13)*(t>>9&3)&127
Combination stimmer + Street Surfer
(t*(4|t>>13&3)>>(~t>>11&1)&128|t*(t>>11&t>>13)*(~t>>9&3)&127)^(t&4096?(t*(t^t%255)|t>>4)>>1:t>>3|(t&8192?t<<2:t))
Stimmer but it uses 1583736's Cool waveform i guess (32KHz Floatbeat)
w=a=>(abs(1-abs(.5+cos(a/64.25))**.3)**(1-abs(1-abs(.5-sin(a/63.75))**.5))),(w(t*.09375*(4|t>>15&3)<<(t>>13&1))+w(t*.1875*(t>>13&t>>15)*(~t>>11&3)))-1
Stimmer but with reverb (32KHz Floatbeat, uses lhphr's something something reverb routine)
