Limits the slope of an input signal. The slope is expressed in units per second.

For smoothing out control signals, take a look at Lag and VarLag

### Slew.ar(in: 0, up: 1, dn: 1, mul: 1, add: 0)

### Slew.kr(in: 0, up: 1, dn: 1, mul: 1, add: 0)

#### Arguments:

in |
The input signal. |

up |
Maximum upward slope in units per second. |

dn |
Maximum downward slope in units per second. |

mul |
Output will be multiplied by this value. |

add |
This value will be added to the output. |

(
{
z = LFPulse.ar(800);
[z, Slew.ar(z, 4000, 4000)]
}.plot)
Has the effect of removing transients and higher frequencies.
