+# Delay & Reverb
+
+Add space and depth to your sounds with time-based effects.
+
+## Delay
+
+```forth
+"snare" s 0.3 delay .         ( delay mix )
+"snare" s 0.25 delaytime .    ( delay time in seconds )
+"snare" s 0.5 delayfeedback . ( feedback amount )
+"snare" s 1 delaytype .       ( delay type )
+```
+
+## Reverb
+
+```forth
+"pad" s 0.3 verb .         ( reverb mix )
+"pad" s 2 verbdecay .      ( decay time )
+"pad" s 0.5 verbdamp .     ( high frequency damping )
+"pad" s 0.02 verbpredelay . ( predelay time )
+"pad" s 0.7 verbdiff .     ( diffusion )
+"pad" s 1 size .           ( room size )
+```
+
+## Combined Example
+
+```forth
+"keys" s
+  c4 note
+  0.2 delay
+  0.375 delaytime
+  0.4 delayfeedback
+  0.25 verb
+  1.5 verbdecay
