1. Yan Carlo Rodriguez ECE 3551 Final Project

2.  To make a program that will change the person voice when using the microphone.  Make the LEDs turn on when an specific voice effect is on.

3.  PF8- will turn on and off the system. LED4 on  PF9- will run the effect Echo. LED5 on  PF10- will run the effect Vibrato. LED 6 on  PF9&10- will cause a simple delay to the person voice. LEDs 7 & 8 on  PF11- will increase the effect of both Vibrato & Echo

4.  Is simply a sound played after that same sound has been played. Basically, it is just a delay of the input signal, which is then added with the input to produce an echo.  Example of function: BUFFER1[m]=(short)(iChannel0LeftIn>>8)+2*( BUFFER1[m]/3)

5.  This effect is achieved by evenly modulating the pitch of the signal.  This is accomplished by changing the modify value of the delay-line pointer on the-fly, and the value chosen is determined by a lookup table.

6.  Each LED has their hexadecimal value:  LED4 = 0x01 (PF8 pressed)  LED5 = 0x02 (PF9 pressed)  LED6 = 0x04 (PF10 pressed)  LED 7 & 8 = 0x018 (PF9 and PF10 pressed) For booth to be on we must sum the value for LED7 = 0x08 and LED8 = 0x10 which you end up having 0x018 and turn on boths LEDs at the same time.

7.  The program was successful. Everything worked according as plan and implement in the Visual DSP Environment.  I connected the microphone into the computer to use it as an amplifier. Then press which ever voice effect I want it to hear or use.  The LEDs turn on to confirm that a certain effect is On.
