Choose a vocal plugin with saturation, compression, EQ, and width controls
Use a compressor with medium attack and fast release
Add subtle saturation or distortion
Boost low mids carefully around 150–400 Hz
Cut harsh frequencies around 2–5 kHz if needed
Use parallel compression for more thickness
Layer doubles or harmonies for a fuller sound
Add reverb and delay sparingly
Use a de-esser to control sibilance
Automate vocal levels for consistency
Try vocal chain plugins like channel strips or vocal processors
Test different presets and adjust to taste
