Arduino FFT - help please

I wanted to do this project of a visual balancer with 8x8 LED matrix and sound sensor, but the code doesn't work... Would you help me?

#include <ArduinoFFT.h> // Assicurati di includere la libreria corretta
#include <LedControl.h> // Libreria per controllare il display a matrice

#define DATA_IN 12
#define CLK 11
#define CS 10

ArduinoFFT FFT = ArduinoFFT();
LedControl lc = LedControl(DATA_IN, CLK, CS, 1);

void setup() {
  lc.shutdown(0, false);
  lc.setIntensity(0, 8);
  lc.clearDisplay(0);
  Serial.begin(9600);
}

void loop() {
  double vReal[128];
  double vImag[128];

  // Leggi i valori dal sensore sonoro
  for (int i = 0; i < 128; i++) {
    vReal[i] = analogRead(A2);
    vImag[i] = 0;
  }

  // Esegui l'analisi FFT
  FFT.Windowing(vReal, 128, FFT_WIN_TYP_HAMMING, FFT_FORWARD);
  FFT.Compute(vReal, vImag, 128, FFT_FORWARD);
  FFT.ComplexToMagnitude(vReal, vImag, 128);

  // Visualizza l'equalizzatore sul display a matrice
  displayEqualizer(vReal);
}

void displayEqualizer(double *vReal) {
  lc.clearDisplay(0);
  for (int i = 0; i < 8; i++) {
    int value = map(vReal[i], 0, 1023, 0, 8);
    lc.setRow(0, i, (1 << value) - 1);
  }
}

C:------
