Want to Make stereo

I want to know if you could help me with the code I am trying to make stereo,

I got this code from this:

And I have done slight modification:

#include <Adafruit_NeoPixel.h>

#define PIN 6
#define lightCount 60

// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
// NEO_RGB Pixels are wired for RGB bitstream
// NEO_GRB Pixels are wired for GRB bitstream
// NEO_HZ400 400 KHz bitstream (e.g. FLORA pixels)
// NEO_KHZ800 800 KHz bitstream (e.g. High Density LED strip)
Adafruit_NeoPixel strip = Adafruit_NeoPixel(60, PIN, NEO_GRB + NEO_KHZ800);

//fadeThickness = 0; // CHANGE THICKNESS (0-10)

int vol = 0;
float total = 0;
int fadeCol = 0;
int val[25];
int volLast = 0;
int fadeAmt = 0;
int counter = 0;

void setup() {
strip.begin();
strip.show(); // Initialize all pixels to ‘off’
Serial.begin(9600);
}

void loop() {
fadeCol = 0;
total = 0;

for (int i = 0; i < 80; i++){
counter = 0;
do{
vol = analogRead(A0);

counter = counter + 1;
if (counter > 50){
rainbowCycle(2);
//rainbowCycle(1) Lower number= faster loop

}
}while (vol == 0);

total = total + vol;

}

vol = total / 80;
Serial.println(vol);

vol = map(vol,2153,50,204,20);

if (volLast > vol) {
vol = volLast - 4;
}

volLast = vol;
fadeAmt = 0;

// i+x or x-i x= half strip lenth
Serial.print(vol);
for (int i = 0; i<30;i++){

if (i < vol){

strip.setPixelColor((i+30), strip.Color(138,24,24));
strip.setPixelColor((30-i), strip.Color(157,0,230));
}
else if (i < (vol + 4)) {

strip.setPixelColor((i+30), strip.Color(165,51,255));
strip.setPixelColor((30-i), strip.Color(255,255,0));

}
else
{

strip.setPixelColor((i+30), strip.Color(52,148,23));
strip.setPixelColor((30-i), strip.Color(127,111,11));

}
}

strip.show();

}

void rainbowCycle(uint8_t wait) {
uint16_t i, j;

for(j=0; j<256*5; j++) { // 5 cycles of all colors on wheel
for(i=0; i< strip.numPixels(); i++) {
strip.setPixelColor(i, Wheel(((i * 256 / strip.numPixels()) + j) & 255));
}
strip.show();
delay(wait);
vol = analogRead(A0);
if (vol> 10) {

return;

}

}
}

uint32_t Wheel(byte WheelPos) {
WheelPos = 255 - WheelPos;
if(WheelPos < 85) {
return strip.Color(255 - WheelPos * 3, 0, WheelPos * 3);
} else if(WheelPos < 170) {
WheelPos -= 85;
return strip.Color(0, WheelPos * 3, 255 - WheelPos * 3);
} else {
WheelPos -= 170;
return strip.Color(WheelPos * 3, 255 - WheelPos * 3, 0);
}
}

All I want to do Is have another Analog input (A2) for another strip Pin 8

What would be the easiest way to do it?

Please use code tags and also please state the slight modifications you have done

Also, before you post, please clean it up. Use a standard indentation to clearly show the code blocks. Never put more than one statement per line. Place any brackets by themselves on a separate line. Use blank lines sparingly, no more than one at a time. Before posting the code, use Ctrl-T in the IDE to reformat the code in a standard format, which makes it easier for us to read. Use descriptive variable names, for example "temperature" instead of "t".
