# ece45-project # ECE45-project
Audio synthesizer project created by ECE 45 students, written using the MATLAB language and MATLAB GUI
Will add member names shortly
## Function Prototypes
fuction x = envelope(input, fs, period, attack , decay, sustain, release) fuction x = envelope(input, fs, period, attack , decay, sustain, release)
where attack, decay, sustain release are percentages between 0 to 1 of the period where attack, decay, sustain release are percentages between 0 to 1 of the period
where period is the time in seconds where period is the time in seconds
function x = generate_wave(amplitude, frequency, phase, fs, duration, duty) function x = generate_wave(amplitude, frequency, phase, fs, duration, duty)
function output_timedomain = Filter(input_soundin_timedomain, Fs, LOW, MED, HIGH) function output_timedomain = Filter(input_soundin_timedomain, Fs, LOW, MED, HIGH)
where LOW, MED, HIGH are user-selected variables of any value where LOW, MED, HIGH are user-selected variables of any value
