A bitcrusher class

I ask a lot of questions here (being still the coding noob I am :o) and I'm grateful for all answers I get so I thought I try to give a little back when I can.

I just did a bitcrusher thing and it seems to work fine (using schwa's Bitter to check), maybe someone finds it useful.

Code:

---

// Bitcrusher.h

#pragma once
#include <math.h>

class Bitcrusher
{
public:
  Bitcrusher();
  double process(double);
  void setNumberOfBits(int);

private:
  int mBits;
};

---

Code:

---

// Bitcrusher.cpp

#include "Bitcrusher.h"

Bitcrusher::Bitcrusher() {
}

double Bitcrusher::process(double in) {
  double x = pow(2.0, mBits);
  double quant = .5 * x;
  double dequant = 1.0 / quant;
  double out = dequant * (int)(in * quant);
  return out;
}

void Bitcrusher::setNumberOfBits(int bits) {
  mBits = bits;
}
