| 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. |
