| signal | 
 | 
 A signal or value to be smoothed. Each time an incoming value changes, the rampsmooth~ object begins a linear ramp over a specified number of samples to reach the new value.  | 
| ramp | 
smoothing-size (samples) [int]
  | 
 In left inlet: The word ramp, followed by a number, specifies the number of samples over which a signal will be smoothed. Each time an incoming value changes, the rampsmooth~ object begins a linear ramp of the specified number of samples to reach the new value. The default value is 0.  | 
| rampdown | 
downward-smoothing-size (samples) [int]
  | 
 In left inlet: The word rampdown, followed by a number, specifies the number of samples over which a signal will be smoothed when an incoming value less than the current value arrives.  | 
| rampup | 
upward-smoothing-size (samples) [int]
  | 
 In left inlet: The word rampup, followed by a number, specifies the number of samples over which a signal will be smoothed when an incoming value greater than the current value arrives.  |
