Amplitude

An amplitude follower UGen. Tracks and reports the peak amplitude of its input signal.

===Examples===

// use sound-card input to control pulse amplitude
play {
 // use headphones to prevent feedback!
 Pulse.ar(90, 0.3) * Amplitude.kr(PhysicalIn.ar(0))
}

// compare with known amplitude
play {
 val amp = MouseX.kr
 val in  = PinkNoise.ar(amp)
 val ana = Amplitude.kr(amp, attack = 2, release = 2)
 (ana - amp).poll(2, "discrepancy")
 in
}
