Decay has a very sharp attack and can produce clicks. Decay2 rounds off the attack by subtracting one Decay from another. Decay2.ar(in, attackTime, decayTime) is equivalent to:
Decay.ar(in, decayTime) - Decay.ar(in, attackTime)| in |
The input signal. |
| attackTime |
60 dB attack time in seconds. |
| decayTime |
60 dB decay time in seconds. |

// since attack and decay are a difference of two Decays,// swapping the values, the envelope turns upside down:plot({ Decay2.ar(Impulse.ar(1), 0.001, 0.01) })plot({ Decay2.ar(Impulse.ar(1), 0.01, 0.001) })// used as an envelope{ Decay2.ar(Impulse.ar(XLine.kr(1,50,20), 0.25), 0.01, 0.2, FSinOsc.ar(600)) }.play;// compare the above with Decay used as the envelope{ Decay.ar(Impulse.ar(XLine.kr(1,50,20), 0.25), 0.2, FSinOsc.ar(600), 0) }.play;
