Detailed Description¶

class daisysp::Port;

Applies portamento to an input signal.

At each new step value, the input is low-pass filtered to move towards that value at a rate determined by ihtim. ihtim is the half-time of the function (in seconds), during which the curve will traverse half the distance towards the new value, then half as much again, etc., theoretically never reaching its asymptote.

This code has been ported from Soundpipe to DaisySP by Paul Batchelor.

The Soundpipe module was extracted from the Csound opcode "portk".
