🐿 Chipmunk Vocal Chop

Pitch +6 to +12 st
Speed 120–150%

Vari-speed vocal chop effect. High pitch + fast speed = classic chipmunk. Combine with chop edits in your DAW.

Try: +10 st · 130% for Memphis-style chops

🌊 Slowed + Reverb

Pitch -2 to -4 st
Speed 75–85%

Download processed file, then add long reverb (8–12s decay) + stereo widening in your DAW. The pitch shift compensates for vari-speed lowering.

Try: -3 st · 80% · Hall reverb RT60 = 10s

🪴 Chopped & Screwed

Pitch -3 to -5 st
Speed 70–80%

Houston DJ Screw formula. Slow the tempo to ~60–65 BPM equivalent then chop 2-bar loops in a DAW. Chorus sections screwed hardest.

Try: -4 st · 75% → chop every 2 bars

🎼 Key Changes

Semitone → Key Chart
+2 = whole step up -5 = perfect 4th down

C → D: +2 | C → G: +7 | C → F: +5
