ArrayMin

Extension

Description

Finds the minimum value in an Array of UGens, and outputs the value and the index.

This is for use in a SynthDef. If you simply need to find out which is the minimum in an array of numbers, use the minIndex and/or minItem methods defined for any Collection.

Examples

Here we generate a three-channel signal containing some simple test curves, and analyse it to generate a plot:s.boot; ( { var son, val, index; son = [ Line.ar(10, 1, 0.5),  // a linear descent in half a second XLine.ar(1, 10, 1),   // an exponential ascent in one second DC.ar(3)              // a constant ]; # val, index = ArrayMin.ar(son); [val, index] }.plot(1, minval: nil, maxval: nil); )

Here we use the operation as an audio effect:( x = { // A collection of different tones: var son = SinOsc.ar((100, 100.3 .. 110)); var val = ArrayMin.ar(son).at(0); val = LeakDC.ar(val); // the operation tends to induce DC offset Pan2.ar(val) }.play ) x.free
