Examples

rampsmooth~ performs linear smoothing on an input signal

Arguments

ramp-up-samples [int]

Optional

Number of samples for ramp-up

ramp-down-samples [int]

Optional

Number of samples for ramp-down

Messages

ramp

Arguments

sample-count [int]
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

Arguments

ramp-down samples [int]
Specifies the number of samples over which a signal will be smoothed when an incoming value less than the current value arrives.

rampup

Arguments

ramp-up samples [int]
Specifies the number of samples over which a signal will be smoothed when an incoming value greater than the current value arrives.

signal

Each time an incoming value changes, the object begins a linear ramp over a specified number of samples to reach the new value.

Output
