woodwenv

(ee2200/woodwenv.m)

Function Synopsis

[y1,y2] = woodwenv(a,s,r,Fs)

Help text

WOODWENV	produces amplitude and mod. index envelope functions 
		for woodwinds
	   usage: [y1,y2] = woodwenv(a,s,r,Fs);
		where a = attack TIME
		      s = sustain TIME
		      r = release TIME
		     Fs = sampling frequency (Hz)
		returns:
		     y1 = amplitude envelope
		     y2 = modulation index envelope
  note: attack is exponential, sustain is constant, release is exponential
