Bitcrushing is an effect that is used often in modern music.
But how do they work?
To my understanding the amplitude of the digital steps are the same no matter the amount of bits used. Iaw: more bits just means you can go further down before you enter the noise.
But if you chop of bits with a crusher, the signal level stay´s the same.
What´s going on?

If you define quantization error as the difference from some reference version of the original then you are right. However, in practical terms there will be no difference in the effect that it has. The "stair-steppiness" of the result will be the same magnitude either way, and it will be just as audible or inaudible whether you round or truncate.
