%Written by Darell and Anne
%If there is a frequency of 200Hz:
%1. it needs to ramp up a frequency from 0Hz to the 200Hz over the attack time
%2. It needs to ramp down to a set sustained frequency over the decay time e.g. 160Hz < 200Hz
%3. It maintains this 160Hz until the release time
%4. Release time: It decays from 160Hz further all the way back to 0Hz.

% DOCUMENTATION:
% phase shift is in number of periods
% fs is the sampling frequency: how many sample points per second
% duration is time in seconds
% duty is a number between 0 and 1
function output = DarellAnnePitchEnvelope(input, Fs, attack,decay,sustain,release) %percentages for attack, decay, sustain, release
len = length(input);
